    If it looks like plain water, that's about the only thing it could be---the AC drain. Yes, most of them do drain right about at the firewall---of course, it is possible that the AC drain tube is dislodged or has fallen off, making the draining a bit sloppy. I don't think a little water is going to hurt your transmission.

    I just bought a CarMD device and I've read a lot of positive feedbacks and a few negative ones. I would like to open this topic so we can share our experiences with CarMD, I will post mine once I use it =P :) I'm not sure if there's a previous topic about CarMD but I used the search feature and it didn't bring anything up.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    well it looks like a very simple code reader and my impression is, after reading about it, is that it would be of very limited usefulness----also the claim that it tells you what's wrong with your car---lacks all credibility.

    It claims:

    "If a problem is found, CarMD tells you in simple English what's wrong with your vehicle, what's needed to fix it and even how much it will cost in your area."

    Even a $3000 diagnostic tool can't do that---so you're getting it for $19.95?

    Er....I don't think so.

    Also, the device limits your use and cannot reset codes---and I suspect will miss a lot of codes as well.

    you know, for the money, it's probably better than nothing, but I think one has to have realistic expectations.

    I personally wouldn't buy it because I need to reset the codes---also a code doesn't tell you what component is defective--it only tells you what system or circuit is in distress.

    So relying totally on this device will probably lead to a lot of parts being replaced unnecessarily.

    on the other hand, it does give you some information to tell to a mechanic, so that's maybe worth $19.95....or you can have Autozone tell you the code for free.

    For $10 more you can get an Autel MS300 CAN OBD II scan tool at Amazon and get free shipping. Plus there's others for about the same. It's not the Cadillac of scan tools but does everything I ever needed.

    Hello...No, I can't find the low coolant sensor
  • euphoniumeuphonium Member Posts: 3,425
    Look inside the over flow resouvior. Passenger side by the cowl.
  • maejinmaejin Member Posts: 11
    Thx for posting but I know where it should be...It's not in the over flow tank

    Air in the cooling system makes your car over heat...the car is not over heating.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    true, sometimes, but not always.....what you'll get is a fluctuation of coolant level and a corresponding erratic display on the temp gauge, if you have one.
  • maejinmaejin Member Posts: 11
    Not having a problem w/ the temp gauge...the low coolant light is on and we can not figure out how to shut it off...otherwise the car is fine...it's not over heating, the fan is coming on and there is enough coolant in the system...we just can't find the sensor which is not in the over flow bottle...the only sensor we found was at the bottom of the radiator.

    has anybody had trouble separating the rubber to metal brake line connection on a 2005 mazda tribute? the front passenger side line blew, so we removed the line from the caliper, removed the spring and loosened the strut bolt to release the line, then removed the spring and loosened the rubber to metal line fitting, but we can not separate them, any tricks? or maybe we missed a step? any feedback would be appreciated. thanks 2,3l, auto, fwd, 105k

    I bought the car used and the transmission immediately self destructed.The car had 89,000 miles on it and the dealer replaced the transmission w/ a rebuilt. I have had no
    problems and it works like a dream,but I have just gone over 10,000 miles w/ it and I
    mentioned it to my mechanic and he said I should have it serviced,change the fluid and clean the filter and all. With new parts spinning at high speeds and all that made
    sense,but after checking the website, I have gotten mixed messages about this.Is it
    better to service it, or leave it alone? It is not an expensive service and if it will extend
    the live of the car,then lets do it.But I'm not one to waste $78.
    Thanks,
    Andy
  • kiawahkiawah Member Posts: 3,666
    Personally if it were mine, I wouldn't touch it.

    You don't change fluids in 10K mile in a brand new transmission, why would you think to change it in a rebuilt one?
  • euphoniumeuphonium Member Posts: 3,425
    If it runs smoothly and doesn't shudder at slight acceleration, leave well enough alone.
  • burdawgburdawg Member Posts: 1,524
    Unless your using it for some severe service, like lots of towing, I would leave it alone. Trans service at 50K intervals is usually good enough, and is more than most of them get.
    Also, make sure the filter is changed, not just "cleaned".
  • colin_lcolin_l Member Posts: 591
    There should be a nut to loosen and then a clip. I'm not speaking with authority about your Tribute in particular as I've never worked on one (or an Escape), but I've done a number of brake lines.

    Here's a picture tutorial: http://www.lexls.com/tutorials/brake/SSbrakelines.html

    I realize it's a Lexus, but that looks exactly like what I did when replacing brake lines on other cars.
  • andyrnandyrn Member Posts: 3
    Thanks,
    I could use the money elsewhere and it has been having no problems.I appreciate the feedback.
  • andyrnandyrn Member Posts: 3
    Again,thanks for the heads up on that. I checked the internet on that and it depends
    who you ask.The prevailing wind says,"if it ain't broke,don't fix it".So I won't.

    Year/Make/Model: 2001 Chevy Tracker
    Type & Size of Engine: 4 cylinder 2.0 liter (with AC)
    Transmission Type: Auto
    Mileage: 65K

    Problem: Vibration at idle. Vibration gets worse when in gear.

    Other Info:
    -Idle speed looks like about 600-700 (when warm), but drops below 500 when put in "D". (as best I can tell from the tach)
    -When cold, it's pretty smooth.
    -I replaced both engine mounts last week (one was broke). I didn't check the transmission mount.
    -The radiator leaks slowly. The engine has sometimes been running a little hotter than usual (when the coolant gets low) but has never been overheated.
    -It never stalls.
    -It always starts right up, hot or cold..

    I'm trying to fix this for my lady. She takes real good care of the car, and it looks almost new. Ever since the extended warranty ran out, I became the mechanic. ;)

    Any suggestions would be much appreciated. I can replace any part that needs replacing (I haven't taken any of my own vehicles to a shop since 1989), but sometimes I need help with diagnosing... Thanks in advance :)

    Jim

    PS, we already got a new radiator. It's going in tomorrow..

    i have a 1996 chevy s10 4x4 pickup. the brake lights stay on all the time. i have replaced the stoplight switch and i still have this problem. any ideas.
    thanks,

  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    disconnect the brake light switch completely and see what happens. If they stay on, then you must have a short to ground somewhere. If they go off, buy another brake light switch.
  • bieksbieks Member Posts: 7
    thanks for your feedback. this is the second time i had to replace this switch in the last year. the first one lasted until now. they still stay on when the switch is disconnected. i cant locate any ground problem. any further help would be great.
    thanks,

  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    Not much I can say without having a really good wiring diagram of your car in front of me. Some brake light circuits route through the multi-function directional switch.

    Since your brake light switch "makes" a ground when you press on the pedal, I can only assume that the circuit is grounded somewhere before it even gets to the brake pedal switch.

    WHERE that is, well, it's anybody's guess.

    If I were you, and I could determine that the circuit does run through the directional switch, that's probably what I'd look at.

    These types of problems can be nasty.
  • bolivarbolivar Member Posts: 2,316
    Most brake lights are hot all the time to the brake switch. (With key off, press the pedal, most times the lights will lightl.)

    Wired this way, there isn't much way a bad ground can cause a problem with staying on, only with not lighting up at all.

    You are getting juice to the brakes all the time. If your brake switch wire is disconnected and they are still on, it is getting juice some other way.

    Is the brake light on all the time, no matter if key is on or off? If so, then who knows where the juice is coming from.

    If they are on only when the key is on, then there is probably a problem with the multi-switch. It flashes the brake light for the turn signal. Or, if someone has been cutting into the wiring somewhere, like a trailer wiring package, and these wires are all crossed up, it can mess up the turn signals bad.

    The emergency flasher is also hot all the time and leads to the brake lights. Has someone been cuting into this?

    I have about 6 quarts of transmission fluid I bought, well, a long time ago. Maybe around 8 years. It's never been opened. I was wanting to try to use it as no one wants it. Is it still good? It's not like milk or yogurt that comes with an expiration date is it?

    like brake fluid? That is the only thing that would worry me, although if it has always been sealed, probably not a big issue. And I have no idea how you could tell.

    Actually, just put it in the car. if they tranny craps out, it was probably no good.

    I have an ACDelco Professional battery I bought 4 years ago. There has been some white powder on the battery (I know it is due to corrosion but is there any way to stop it?) and a mechanic said two of the 6 cells are bad. ACDelco's web site says "Should this battery fail to hold a charge due to a defect in material or workmanship, it will be replaced ..." What is a battery "holding a charge"? Is it a more stringent condition than, say, two of the 6 cells are bad? is it possible that 5 out of 6 cells are bad and the battery can still "hold a charge"? And how can one determine whether it is a defect in material or workmanship that causes the failure to hold a charge? Do battey manufacturers usually get away from their warranty?
  • kiawahkiawah Member Posts: 3,666
    edited September 2010
    There are 6 cells inside the battery, each cell should be in the range of 2.2 to 2.3 volts when charged, but you can only measure the combined total.

    If a cell goes bad, it will typically 'short out', so it has zero volts and your total voltage would be in the 10-11 volt range.

    A 4 year old battery is typically either at the end or nearing the end of battery life. I know that some mfg's say 5 year, 6 year, 7 year etc.....and I've had some individual batteries last that long, but if I get 4 years out of a battery and start to notice anything wrong at all, I replace it. I've found northern colder winters are much harder on batteries, than now living now in the south. So at the first hint of having battery problems, I just replace them and move on. Next one will be good for another 4-5 years timeframe.

    It's not worth being stuck somewhere, or need a tow somewhere, over a 50-75 dollar battery. Replace it on my terms when I want to, not when the vehicle is stuck somewhere. Also, with the electronics in today's newer cars, you actually want to change the battery while maintaining power to the computer, and auto repair chains will typically loan you a small battery pak which you plug into the computer plug to achieve that.

    You can get the white powder off with baking soda, small amount of water, and a wire brush. Do not splash on the paint. The powder is acidic, the baking powder a ''base', which neutralizes the acid. I then coat with a thin coat of petroleum paste, or there are other things you can buy at auto parts store.

    But if it were me, 4 years and corrosion....battery is gone.

    P.S. and I highly doubt you have two cells gone. Your vehicle would appear totally dead, and probably you couldn't even get it to jump to start. With one cell out, it's extremely limited.
  • srs_49srs_49 Member Posts: 1,394
    White powder around the terminals is normal. A little baking soda mixed with water (to neutralize the acid) and a old tooth brush will clean it right up.

    If two of the cells are bad, then the battery should be replaced under the warranty, whether or not it is holding a charge. If the cells are really bad, than the amount of charge the battery can hold (battery capacity) is reduced.
  • colin_lcolin_l Member Posts: 591
    edited September 2010
    You can significantl inhibit-- if not entirely prevent-- the white powder by using a small bit of dielectric grease on the terminals and putting a non-conductive spacer between the cable and battery... usually they are kind of a felt material at the auto parts store, small red and green discs.

    I had a battery go six years with no corrosion using this method. It was the record because I often sell cars way sooner than that. ;)
  • kiawahkiawah Member Posts: 3,666
    btw,
    If you have a battery replaced under warranty, then they are pro-rated as per the number of months already gone. It forces you back to the same place you bought the original battery, and you may or may not find the resultant 'deal' the best, when compared with competitively shopping for a new battery.
  • burdawgburdawg Member Posts: 1,524
    "Holding a charge" is the general term used to describe a batteries ability to maintain it's voltage without being recharged over time, when no load is attached to it or it's at rest. Of course if it's in use it will need to be recharged to meet the criteria.
    The classic way to test a battery is to first verify it's fully charged by measuring the voltage. If it's good a load tester is applied to see if it will maintain that voltage under a specific load.
    Another test is to take a fully charged, disconnected battery and monitor it's at rest voltage over a period of time to see if it is maintained or gradually drops over time. I do this with my boat batteries quite often. A lot of times an older battery that passes the load test will still gradually lose charge over time, which is warning you that it won't be much longer before it will need to be replaced.
    You need to remember though that in all modern cars (and many boats) there's always some load on a battery. The radio memory, keyless entry, security, etc all put small constant loads on the battery. For long term storage a float charger isn't a bad idea.
  • hzmontehzmonte Member Posts: 16
    "in all modern cars there's always some load on a battery" -- then does that mean the battery manufacturer's warranty condition "if the battery fails to hold a charge" would never be met? Not to mention the need to prove that it is due to a defect in workmanship!

    I recently asked if it was a major over haul to fix the blending door or cable of a '92 camry.. (the blower fan does not defrost the windshield now) but works great on the face and feet setting) and Mr Shiftright did reply to this question, thanks to him..
    Now we would like to know , does this repair ALWAYS involve taking off the dashboard of the car? can it be done from under the hood? We would like to try to do this ourselves, and can not find anything in our book that came with the car//
    I called one auto place, ( the dealership where we purchased this car , in "92, and they quoted us a price of 800 to 900 dollars,!!!! I think that price is unreal? or is it???

    thanks again for all your help? we do appreciate it...

    It's behind the dash

    In cars, there is a structural metal thing called a firewall, that separates the engine area from the passenger compartment.

    That's not something that would be in an owners manual. It's covered in the service manuals that garages buy, which contains multiple hundreds of pages. Some of my vehicles that I've bought service manuals for (very expensive), are multiple volumes of books. I have one 3 volume set which is about 6" thick.

    This isn't a repair you should attempt, you have more chance of ruining something else, than you have of fixing the current problem.

    Take it somewhere that knows what they are doing (you're paying for the expertise), or live with the problem. (Buy a 12volt fan you plug into the cig lighter, smile).
  • stickguystickguy Member Posts: 53,328
    you can tell by the quote how big a job it is, since the labor is probably about $890 of the $900!

    I guy I know did a photo documentary on replacing (I believe) the heater core on a Volvo 240. Simple, basic car, pretty low tech.

    Well, it took him about an entire weekend, since you basically had to dismantale the entire dashboard and center stack to get at it. And even harder, remember how (and in what order) it all went back together.

    Not something for the faint of heart.

    But, if you want to do any elaborate audio upgrades, this would be the time!

    and it also falls into the catagory of, if there is something else that could be replaced at the same time that is a potential failure item and the part is cheap, do it too while you are in there, since the labor would be the same later.

    I have 2 gm vans 2001 venture and 2002 oldsmobile silhouette. They both have the same problem. The cooling fans only work with AC on. With the AC off they will overheat. Only the passenger side fan works. The driver side fan never comes on with the AC. However, the drivers side fan when jumped to terminal runs just fine. I have replaced the coolant sensor and all relays with no improvement. I have hooked up a Tech 2 scanner and the low speed fans cannot be commanded on. The high speed fans can be commanded on. I did not look to see when doing this if the driver side fan was working. Both vans have the 3.4 engine and both started having the problem around 80,000 miles.
    I know the computer turns the fans on by creating a ground. My question is does anybody know if the computer can cause this problem or what else it may be?
  • ronmatronmat Member Posts: 2
    Where is the computer on my 05 Santa Fe, Im having problems with my
    fans not coming on for Radiator cooling and Condenser fans. I have been told it
    could be my PC not sending the signal to come on.
    Thanks in advance

  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    That's a pretty big leap and seems the least likely of all the possibilities IMO. Upon what testing was this advice offered to you? Which of the three engines do you have?

    Have you checked fusible links for radiator and condenser fan circuits? Fuses for their respective relays? The relays themselves?
  • burdawgburdawg Member Posts: 1,524
    No. The static load on the battery when connected wouldn't have any bearing on the warranty. The condition of the battery would be tested by fully charging it and then load testing it.
  • ronmatronmat Member Posts: 2
    thanks for the Reply Mr Shiftright and this what I have checked already
    I have a 05 Santa Fe with 3.5 liter V6 auto transmission.
    I have checked all fuses under the hood that relate to the radiator or condenser fan. I also checked the fuses in side the car under the steering wheel and all were good. I took the relays that are under the hood and swapped with the horn relay and all three checked out. (I would beep the horn and then swap the relay and bump horn again, thus eliminating any questions of whether the relay was switching when energized)
    I then took the radiator fan connector loose and ran power directly from battery to fan connector and fan then came on. I had both fan motors replaced because that's what the mechanic told me was wrong. I have also turned car on and let temp gauge go to medium and then disconnected the temp switch on engine block and gauge would go to zero on dash. This confirmed that all fuses, relays and gauges that I know of do work. I looked at a schematic and it shows all three relays in series and the PCU is fed a signal from the temp switch. The PCU then sends signal to relays to turn on and send power to fans. I can't even find the PCU on the body of the car? Any help would be greatly appreciated.
  • kiawahkiawah Member Posts: 3,666
    edited September 2010
    Good analysis so far.

    I don't have schematics for your vehicle, but some vehicles use the relays to switch the fans from being wired in parallel (each motor getting the full 12volts and running at full speed), to wiring the motors in series (thereby both motors getting only 6 volts at running at low speed).

    But first things first. Hang a test lead off of the input to the first relay, so that you can put a voltmeter on it. Definitively prove that the Relays are getting the voltage to turn on and energize, or not. You want to do that with the relay in circuit, so that you're effectively testing whether it is outputting enough voltage/current to turn on the primary of the relay....it's testing the voltage 'under load'.
  • Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    I see an item marked "radiator fan control module" but then the database maddeningly takes you nowhere to find this. Are they referring to the car's computer here?

    The ECM looks to be just to the right of the gas pedal, on the transmission hump.
  • hzmontehzmonte Member Posts: 16
    Before my raditor needed to be replaced 5 months ago, the temperature meter shows that it is 50% hot. My temp meter is like the left side of a clock, with the lowest point at the 7 o' clock position and the highest point at the 11 o' clock position, so the 50% reading is at the 9 o' clock position. (Region between 10 and 11 is the red zone.) When it reached 10 o' clock, I had the raditor replaced. When the new one was freshly installed, the reading is somewhere between 7:30 and 8, but now it is like between 8:30 and 8:50. Is this normal?
  • srs_49srs_49 Member Posts: 1,394
    All of my vehicles with temperature gauges run a little below the half way mark on the gauge. So, using your terminology, that would be 8:00 to 8:30.
  • kiawahkiawah Member Posts: 3,666
    It is likely they changed the thermostat (and hoses and coolant) when they replaced the radiator. That new thermostat, may open at a different temperature than your old.
  • hzmontehzmonte Member Posts: 16
    edited September 2010
    Can this explain the rising reading since the radiator/thermostat was installed?
  • euphoniumeuphonium Member Posts: 3,425
    A new temp sending sensor would be without corrosion (thus not insulating) transmitting the true temp of the coolant.

    I try to be a little cautious when answering radiator questions, because sometime repair work is done without getting to the root cause of the problem.

    As an example, I don't know why you had to replace your radiator.

    a.) you could have had a situation, where everything was fine in your cooling system, EXCEPT, your radiator got physically damaged and sprung a leak. And then you replace the root cause problem (bad radiator), and everything is good in the world.

    b.) you could also have had a situation, where you have a bad head gasket. That bad head gasket is causing exhaust gases to enter the coolant chamber, overpressurizing the cooling, which blew out your radiator. You know nothing about the head gasket problem, all's you know is your radiator is bad. You fix the radiator, but all is not good in the world. You still have the original root cause problem, and therefore you will still have problems and other cooling symptoms that will show up.

    There are other scenarios that could play out, I only give you those two of examples of the same symptom of a bad radiator, but two totally different root cause problems.

    So monitor closely your cooling system, and make sure it's not getting overpressurized, make sure when it's cold and you start it the coolant is topped off (if refilled itself from the overflow when it cooled), make sure when you start it the coolant isn't moving (thermostat is closed till the engine warms up), make sure as the engine warms up to temperature the coolant starts to flow (confirms thermostat is openeing, and that water pump is pumping), make sure as it continues to warm, that the radiator fan turns on, cools it down, then turns off. Etc.
