    Hi Traci,

    I have the same issue and had a diagnostic performed. They did a pretty good job locating and understanding the problem. I went through the same crap trouble shooting and replacing parts. End result is the timing chain cover gasket has a small leak. The leak is leaking on the engine down to the oil pan and if I have it fixed will cost me over $1000 in parts in labor. The cheap way out is to make sure that there is always enough coolant to sustain your car so it doesn't get hot. I hate Fords.

    We have a 1998 Sunfire with the 2.2L engine that has started overheating. Changed the thermostat, water pump, and surge tank cap. It would heat up to 200°,(have digital scanguage hooked up to keep an eye on actual temp instead of just using the dial guage in car) but not enough to overheat. Also, the surge tank would check low and when you add fluid it would start blowing fluid out the cap. The coolant light has started coming on and now stays on.
    Today it overheated and I let it cool down to start home. Less than a quarter mile down the road, the temp jumped up to 250°. Does anyone have any ideas on what I need to do to get this fixed.

    With that fast an overheating, I think you are driving a tea kettle---that is, your engine is boiling the water through a cracked exhaust port in the head.

    Have you checked the coolant for the presence of combustion gases?

    I have a 98 buick park avenue. My thermostat stuck so i took the guts out and filled the radiator up with regular water to get it back home. I put in new thermostat in and drove it down rode it cut off and would not crank back up. Went and bought new battery. I got it back home and read in the manual not to put just regular water in radiator so i put the 50/50 mixture of dex-cool and water in it. Know it sounds like it might be the crankcase bearing or the rod making a horrible noise. The gauge on the dash was half way from hot and cold. The digital read on the car only got up to 207 degrees. Do you think that the regular water caused me this much problems. do you have any idea what the noise might be in the motor.

    I have a 1988 Chevy Spectrum. 260,000 miles. Ran fine until recently.
    February 2007: car overheated, heavy white exhaust, lost antifreeze. Mechanic at private garage checked it, said it was bad head gasket, but heads were not cracked. Repaired HG for $900. Few weeks later: new oil leak started from crankseal, losing abt.a quart a month. Mechanic said oil leak is from increased pressure caused by better seal from new HG. Said it was cheaper to add a quart ea. month than to repair. I can live with that if he can. Added quart ea. month for 12 mos. Feb. 2008: oil leak got worse overnight. Mechanic said crankseal was worse and the camseal now leaked. Repaired both & installed a new water pump which I didn't know was needed. He also said my engine had high "blow by" & they cemented the two seals in to keep "blow by" from causing leaks again. April 2008: In traffic, radiator fan came on a little later than usual but it worked and no overheating occurred. Antifreeze down about a qt.- was refilled. Next day: No leaks found. Drove two miles. temp gauge needle goes to "H" fast. Interior heater & fan is out. I shut down immediately. Sat along the road for 20 minutes to let it cool. Drove home. Antifreeze down about two quarts. Few days later: no driving. radiator is full. I start the car, left it idle. Temp.gauge still showing not warmed up to normal yet. Wife saw white exhaust - nothing heavy. Then, antifreeze is forced out of coolant overflow. Mechanic said it is bad headgasket. I said "how, it's only a year old." He said I must have been running it hot. I said "no way -never overheated all year until a few days ago." He said: maybe cracked head. I said heads were fine last year. He said "well, that's the way it goes."

    I read that this could be anything from cracked head, to bad radiator cap, to thermostat issue. What does everyone here think my problem? Given that the headgasket is new, and it never overheated for 12 months, is it likely to be a headgasket again?

    JR,

    Regular water would be just fine, that would not have caused your problem.

    You may have a bad water pump, making the horrible noise, not pumping, and causing your engine to overheat.

    The thing to do, while the engine is cold, is to disconnect the accessory belt. Then start the engine to see if you still have the noise or not. If no noise, then the problem is with one of the accessories driven by the belt. If the noise still exists, then get your vehicle to a repair shop quick so you don't ruin the engine any worse.

    Assuming the noise stopped when you took off the belt (most of the times accessory goes bad before an engine bearing), then turn off the engine....and begin turning each accessory slowly by hand, feeling for whether it turns easily without wobble or shimmy. You can usually feel which one is bad, then just replace the defective part.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    You can pressurize the cooling system with a pump, then pull the spark plugs and look for coolant on them or crank open cylinders to see coolant coming out.

    The only way to test for a crack head is to remove it and have it flow tested or magna-fluxed, there is no other sure way.

    Perhaps the head was warped last time and did not seal properly. As for "blow by" that is a sign of a worn out engine (bad piston rings).

    If it IS the head gasket, given the mileage, I think it's time to bail on this car.

    Hi,

    I have posted here before about my car burning coolant. I have been running the car for the last 6 months by manually topping off the coolant on a weekly basis. Not sure how much longer the engine will last this way.

    I would hate to spend money to buy a new car right now as the Lancer is not really old and only has 69K miles on it. What other options do I have inorder for me to fix this problem without buying a new car? Estimates that I got for head gasket repair and reliability of the repair do not give me a warm feeling.

    What about putting in a new engine in the car?
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    I don't see why you can't just fix the head gasket. Lancers are pretty good cars and if the repair is done properly, the engine should last a long time. But you are right, running coolant in your engine is going to harm it eventually.

    The book says about 5 hours labor to replace the head gasket plus about $75 for gaskets. Plus new coolant, etc. So what kind of estimates are you getting here?

    Hallo,

    Please, help me ... my car is 300 M Chrysler Model 2000. The problem is the Gearbox oil goes to the Radiator. I have checked the Radiator my self and found no Leaking from the Gearbox Coolant in the Radiator.

    Anybody may have an idea if any other point other than the radiator that leak the Gearbox oil to the Radiator.

    Thank you,
  • bolivarbolivar Member Posts: 2,316
    I think what you are saying is the automatic transmission fluid is leaking into the coolant in the radiator.

    Yes, this could be happening, and is very serious. It will ruin the automatic transmission if not repaired.

    The automatic transmission fluid has a small, separate cooling tank inside the radiator. Transmission fluid is pumped through this tank to cool it down. There are two steel lines that go into the bottom or side of the radiator carrrying the transmission fluid.

    If the cooling tank inside the radiator is leaking, then yes, you get transmission fluid in the coolant fluid in the radiator. And you are getting coolant in the transmission, which will ruin it.

    Hallo, bolivar,

    Thank you for intcepation with my car's problem and I really do appreciate your help... I see what do you mean ,but I removed the Radiator last week and I checked if the Coolaint is leaking ( here is how I checked it. I sucked by my mouth through the one of the lines and closed the other one by my finger... There was no leaking even I keep trying several times) .. so I am wondering if this way is enough to judge cuz the oil goes to the Radiator within one hour .... ( it would be very enough to discover the leaking the way I test it)

    I am thinking if may be the Coolaint in the Radiator is OK , what would be the other reason to have this problem arise.

    Best regards,

    anazim1
  • dgrasserdgrasser Member Posts: 12
    Is it gearbox (motor oil) or transmission fluid (automatic transmission)? Transmission fluid is usually reddish in color. Motor oil is more brownish and darker.
    Your automatic transmission likely has a cooler that is actually part of your radiator, or, a separate unit. Either way the transmission fluid circulates through tubes that is cooled by the surrounding anti-freeze that is also cooling your engine.

    If the seals or the tubes for your transmission cooler leak, you will see transmission fluid (oil) in your antifreeze. Worse yet, you will also end up getting antifreeze into your transmission which can be very damaging to your transmission.

    You should stop driving your vehicle immediately and have a mechanic determine what it leaking. If it is seals, you may be able to replace them, but if is the tubes, you will likely need a new transmission cooler. If the transmission cooler is part of your engine cooling system (radiator), you will need a whole new radiator.

    You can probably find a used one, but may end up with the same problem later. If you are going to keep the vehicle of a long time, I would pay the extra money for a new transmission cooler (or radiator).

    I just went through this with my Dodge Caravan. They had to flush the transmission system three times to get all of the antifreeze and coagulated gunk out of it, but you have to do this to protect your transmission.

    Hope this helps.

    Thank you Dqrasser,

    it is the transmission fluid,which is going to the radiator. I will change the Radiator cuz I think this is the right thing to do and I will update you.

    Thank you again

  • bolivarbolivar Member Posts: 2,316
    I agree with degrasser, if putting in a new radiator fixes the problem, and I hope it does, you will need to get the coolant out of the automatic transmission.

    You will have to remove the bottom pan on the transmission. It does not have a drain hole. And I also agree that you need to do this about 3 times, in order to try to get as much of the coolant out of the transmission. Put the pan back on, refill with the correct transmission fluid (your owner's manual in the 'specifications' section should tell you what type of fluid to use), run the car for a few minutes, shifting the transmission between all the different gears, then do this all two more times.

    I really don't know what to tell you about your 'test'. I do not know what kind of pressure the transmission fluid is at when pumped through the radiator. Maybe you were not able to put enough pressure on the tank to feel the leak.

    But the tank inside the tank is the only place I know where coolant and transmission fluid come close to mixing.
  • anazim1anazim1 Member Posts: 4
    Thank you Bolivar,

    I very much appreciate your assistance. And as I mentioned earlier that now I am confensed to replace the Radiator.

    The very interesting thing is what you have mentioned that the Tank in the Radiator is the only Place that the Transmission Fluids and Coolant get closer which support the idea of maybe leak is there and only very strong pressure under certain Temp could enable us to discover the leaking.

    Please, accept my best regards, I will up date you soon.

    Does anyone do radiator repair these days? Or do they just replace radiator.

    A radiator repair shop could tell you if the transmission cooler internal was leaking or not. It's possible the oiliness was sealer or something else and not transmission fluid.

    I took a quick look around here and there and while it may not be as prevalent on the 3.8 as it is the 3.1 or 3.4, it appears it does happen. Lookin at the engine from top down, the valve cover gasket should be first followed by intake gasket . If it is that it may eventually continue to crack and leak into engine oil, wouldn't be good.

    I have an update on my cooling system problem. i.e small amount of oil inside radiator, around the cap, followed by oil residue around lower intake gasket. The low coolant light still comes on for about 10 minutes before going out. I'm also losing a small amount of coolant.

    I took my car in for an oil change today and had the dealership take a look. They said the lower intake gasket was leaking oil (no pressure test), which was what ray indicated. They also said the "coolant elbow" was seeping coolant.

    Questions: The lower intake gasket leak is responsible for the oil in the radiator?
    I suspect it's probably been like this for awhile. Would you have it repaired for $924 at the dealership, or keep driving as is?

    Also, what/where exactly is the "coolant elbow"? I looked at the hoses... they appear to be fine. Thanks.

    It's like if your aorta was leaking. You have the surgeon fix it if you care about what the negative outcome would be if you don't. If the Buick is a throw away, and you don't care about water in the oil and bearings, then let it go. Otherwise, get it fixed quickly. I'd look for an 'elbow' as they describe , as a plastic piece on the radiator fitting, or on the expansion tank.
  • imidazol97imidazol97 Member Posts: 27,671
    I have to look up to see if it's possible for the lower intake gasket on a 3800 to leak oil. It has coolant running through it. I suspect the oil you see is a typical seepage of oil that comes up around the bolts and odd places there and collects in the little low spots. You can always take a long screwdriver and press a shop towel into those areas and soak up the oil residue, the heavy gooey stuff. Then see if it returns.

    As for the elbow, the 3800 has an elbow that comes out of the lower intake manifold, the metal part, right below the PCV valve in the upper intake manifold. The 1/2 inch diameter black plastic makes a turn and goes into the base of the tensioner pulley. The coolant goes through there to the heater hose. This elbow is plastic and is sealed at both ends with an o-ring. They sometimes seep. You should be able to visually see a brown track if you have DexCool which is orange brown. If you don't see much of a seep or leak, don't worry until something else has to be worked on to change it. It requires removing the tensioner pulley unit and carefully working the o-rings and new one into place.

    As for the oil in the radiator, is it motor oil? Is it transmission oil? If you have DexCool you may have an oiley looking material if it's not been changed soon enough or if someone contaminated it with green stuff type antifreeze.

    I'd drain the antifreeze and rinse with water a couple of warmups and then drain. And refill with correct amount of DexCool. Then see if the oil reappears.

  • imidazol97imidazol97 Member Posts: 27,671
    An oiliness could be from one type of leak sealer too. I recall one that did that.

    That's why I'd suggest a flush in the driveway at home where you take off the lower radiator hose and run water through the radiator and then add DexCool and refill.

  • jipsterjipster Member Posts: 6,296
    Thanks for the comments kiwah and imidaz. I took a look at the engine again this morning. There seems to be slight oil seepage in what I believe is the valve cover gasket, and also the lower intake. I recall when I bought the car the gasket area was only slightly damp. Now there is just a little bit more around the bolts and low spots with the heavy gooey stuff imidaz indicated. But, it has never leaked oil, nor burned oil. It is only slightly worse than when I bought the car (4 years ago).

    I located what I believe to be the coolant elbow (right above the water pump) That area is damp with oil where it comes out the lower intake. Doesn't seem to be coolant though... could be coolant and oil. I never have the burning coolant smell though.

    It's been about 3 years, and 20,000 miles, since I changed the Dexcool. I'll probably go ahead and drain,flush and refill as you suggested. Thanks.

    Hi I have discovered copper coloured particles in my radiator coolant does anybody know what this
  • kiawahkiawah Member Posts: 3,666
    Perhaps pieces from a water pump going bad?
  • imidazol97imidazol97 Member Posts: 27,671
    If you haven't owned the car its whole life, it's possible someone put a cooling system sealer in that has flakes that color. I think I've seen something like that on store shelves in the past as a stop leak.

    Isolate some of the particles and use a sharp device to see if it's truly metal or an organic material.

    Has anyone ever replaced the inlet water hose. It's the hose going from the thermostat housing to the pump inlet water pipe? Do I have to take the intake manifold off.

    I have a 93 Bonneville, 3.8 v-6.. Car has 193,000. Great car until today. I pulled out from a side road that was on an uphill grade onto a four lane highway. I was in the left hand lane when the car just stopped. At first I thought it was the battery or the alternator. Replaced the battery had the alternator checked they were fine. The car will crank but not start. Could it be the fuel pump or not getting a spark somewhere?? I had the car towed to the garage and they are waiting a day or two to check it out. HELP
  • imidazol97imidazol97 Member Posts: 27,671
    Turn the key to ON. Do you hear the fuel pump run for about 3 seconds? Might not be pumping but it's running.

    You can check for fuel at the shraeder valve on the fuel line on the motor. But having gas spray out does NOT mean there's enough fuel pressure.

    You can check to see if injectors are firing by putting the pins of a 194 light bulb into the socket for one of the injectors. It will flash-I'm told. I have not done that. That will tell you if the computer is firing the injectors.

    Check fo spark by pulling a spark wire and laying it a quarter inch away from a metal ground and crank the motor--or better put an old spark plug on it and lay the plug on the block.

    My first guess woud be a crankshaft sensor. But those often restart after they've cooled.

    You're needing to check for air, spark, and fuel.

    my 2002 jeep cherokee cooling fan does not come on. the engine temp goes up when the car is not moving. tough to ride in stop and go traffic. i checked the fuse. what my next step. what contols the fan.
  • burdawgburdawg Member Posts: 1,524
    There's a sensor somewhere in the cooling system to turn the fan off and on, probably via a relay to handle the current load. Before doing anything else check to make sure the fan hasn't gone out. If you connect it to 12VDC it should run.
  • 0patience0patience Member Posts: 1,712
    Probably a problem with the radiator cooling fan relay.
    It is located behind the front bumper fascia below the right headlamp.
    Some genius thought it was a good idea to put it there. :surprise:

    I have an '97 Audi A6 Quattro AWD vehicle. I recently took it on a trip that was about 800 miles round trip. On the way out I had no issues with my vehicle, but on the way home I got stuck in a traffic jam and my car started to overheat. I initially thought that I had a coolant leak because I started to have smoke/steam coming out of my car and it had that sweet smell to it. Upon further inspection I noticed that my resevoir tank was a little low and there was evidence of coolant spray on the inside of my hood. I could not find where the leak was coming from though. I had extra coolant in the trunk of my car. In the meantime someone passing by stopped to help me. He said that he was familiar with cars and took a look. He too couldn't find anything that would suggest a leak. We decided to open the resevoir tank, which was a mistake. As soon as the cap was opened all of the coolant inside the tank boiled over. Long story short, I ended up getting a tow to a gas station where I picked up some coolant. I was in such a hurry that I grabbed the non-diluted and the tow truck driver had put it into the car for me before I realized my mistake. He didn't seem worried by the mistake and said that the car should be just fine, but I should make sure to get a flush before winter. Should I be concerned by placing non-diluted coolant into my vehicle?
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    Not a problem. Your REAL problem is finding out what happened. You should have the cooling system pressure tested immediately for hose leak, radiator leak and head gasket issues.

    If your Audi engine should overheat BADLY one day, that's it for your engine, it's toast, and the car is literally totalled. So you've got high stakes riding on finding this problem and fixing it as soon as you are able to do so.

    Pressure in the reserve tank is not a good sign, so I'm a bit concerned.
  • bolivarbolivar Member Posts: 2,316
    Some GM auto have what looks like a 'reserve tank' is actually part of the pressurized system. It does not have a flimzy cap, it will have a regular pressure cap.

    His Audi may have this kind of system. When they took off what they thought was a reserve tank, they actually opened the pressurized system, which would immediately boil, especially if it was overheated.

    I had a rather sizeable leak yesterday AM under front end of 2006 Civic 5 speed EX, 37000 miles. My leak was obviously green antifreeze. Added H2O, went to work, topped off last night w/ H2O, another small puddle this AM (maybe 2 cups or so). Have appointment with dealer Thursday, car rental lined up (I commute) and have a water bottle with me!
    Ideas??
    Oddly, I have in the last couple of weeks noticed a funny smell when I'd turn on the AC. This is not the first time I've used the AC but it IS the first time I'd noticed the smell and meant to have it checked. The antifreeze puddle upped the ante. Could there be a connection? However, this is NOT the normal condensation puddle after using the AC. There's too much of it. Otherwise the car runs great. Anyone out there with antifreeze leak info? The car's been in no accidents and I'm the original owner. Drat - I buy Hondas so things like this don't happen!!!!

  • cmruffcmruff Member Posts: 15
    The problem turned out to be a CRACKED ENGINE BLOCK. The funny AC smell, of course, was from the leak.
    The car is 1000 + a few miles out of warranty (37150 miles)
    The dealer told me they had done the same repair a couple of months ago on another 2006 Civic..
    Honda is shipping new parts and the repair will be at no cost to me and I didn't even have to ask! I certainly didn't have to plead.
    My faith in Honda is completely restored!!

    But cars aren't supposed to have cracked engine blocks. There's a problem. Replacing parts is nice, but it would have been better to engineer and build better to begin with.

  • cmruffcmruff Member Posts: 15
    Yeah, I know newish cars shouldn't have cracked engine blocks. The mechanic suggested it could have been unseen porosity in the casting that didn't break apart at the beginning.
    On the other hand, 2006 was the first year of the new model and I remember it being hard to even get a hold of one. I had to wait a month because I wanted a 5 speed. Maybe corners were cut? Also, I NEVER would have bought anything in the first year of a major model change, but my previous Civic had been squashed in 2006: I was stopped and clobbered by a 60 mph Suburban and got out with only a goose egg on my head so of course I wanted another Civic. In fact, that crash pretty much cemented my loyalty to Honda; this repair is the icing on the cake.
    Or maybe it just occasionally happens in this NAFTA-esque nightmare of an economy. I've purchased a number of new computers, too - and only one of them had a faulty hard drive, but still, one new computer did have a faulty hard drive. And I've purchased a number of cars; this is my first (I hope only) one with a faulty engine block.
    It does make me wonder about that funny under-the-front-dash buzz I used to hear when I'd go 70 - I wonder if there was a connection between the buzz (which had pretty much vanished by 37000 miles) and the crack. When I brought the then-brand new car in to see about the buzz, they couldn't hear it - they said the local hwys didn't let them go 70?!

    i have a 1998 plymouth voyager with a 3.3 ltr v6. i have replaced the fan module, the water pump (at the shop)and the ecm (myself)but it still overheats when i am driving in town with lots of stops, but will stay cool on the highway. i know the fans are not kicking on when it gets hot. i have not changed the thermostat yet. wondered if you could give me any suggestions? thanks!
  • kiawahkiawah Member Posts: 3,666
    I had a 96 chrysler t&c, which blew out the cooling fan transistors (they act like a relay)....and the fans never came on, causing it to overheat. They are actually mounted down on the frame, so that they use the frame as a heatsink. (Heatsinks keep transistors from overheating and burning up). I had never seen that arrangement before, and only found it because I had a wiring diagram for the car.

    I don't know if the 98 is the same, but it might very well be.

    I guess what I'd suggest is to follow the wiring back from the fans, and see if they connect to something mounted down on the front frame.
  • dgrasserdgrasser Member Posts: 12
    I have a 98 Dodge Grand Caravan with the same problem. There was a recall or service notice on the thermostat device that was mounted on the frame but was having a problem with falling off.
    Look under the NHTSA site or contact your local dealer.
    I think it may have been a service bulletin.

    I have a 2006 Ford Explorer and I have just gotten the fan belt replaced. However the engine coolant sign or whatever it is keeps popping up and my car almost over heats every time I drive it work the past week. Could it be cold weather? Should something be replaced? I'm just really confused because if something was wrong wouldn't someone have noticed it when replacing the fan belt?
  • bolivarbolivar Member Posts: 2,316
    There is very little to 'notice' when replacing a fan belt.

    But they could have messed up installing the belt correctly. Which could lead to the overheating.

    Overheating is a very serious problem. It can quickly completely ruin a motor. You need to have this repaired quickly. I think I would take it back to where you had the belt replaced.

    I just reread your post. You said 'almost overheats'. I thought it was overheating (coolant being blown out of the radiator, etc.)
    What do you mean 'almost overheating'? Is the coolant guage running much higher than before?

    Putting the belt on still could be the reason for a change. For example, you coolant fan might not be running because they knocked an electrical connection loose. (I'm guessing but I would think a 2006 vehicle has an electric coolant fan, not a manual one run off the belt). With the fan not running, if the weather is cool where you live and you only drive a short distance at slow speeds, the car might just show higher than usual temperatures on the guage. If you drive it further or faster, it might overheat more.

    Overall, take it back where you had the belt replaced. Of course, they might reconnect a loose connection, tell you the car needs a radiator flush (should not be needed on a 2/3 year old car) and charge you a lot more money for doing some unneeded repair.

    Hi all,

    2000 Chevy 1500 express van 4.3. 116K.

    One of the plastic tanks on radiator has a crack.

    Can a radiator shop replace the tank or should I buy a new radiator?

    I checked local parts stores and am looking at $ 200 - $ 300. Looked online and can get for about $ 150 delivered. Is there any difference other than the price?

    Thanks
    Jim
