    This sounds like your evap casing is fill up with water and not draining , drain hole may be cloged. If it were coolant, engine temp. would be show higher.

    Yes, of the two important fluid to monitor motor oil and transmission this is one of them. but shop will want to sell you a transmission flush. don't do it. The american transmission builder association does my endorse flushes. again depending what type of vehicle you have a transmission service is the best. A service is dropping the transmission pan and replacing the filter, clean the pan bottom, place the pan back and replace the fluid that only came from the pan. yes, transmission change every 30k the other option is $3000 to rebuild it.

    I have a 1993 Chevy Blazer 4x4 4.3 Vortex. The Tempture gauge comes on full when I start the vehicle and the goes to zero. I have replaced the Coolant Tempture Sensor. The gauge still does the same thing. Any suggestions.

    I have a problem that I want to check on before I take it to a mechanic.
    I have a 1989 Chevy S10 Blazer 4.3L V6 w/ air and ~140K miles on it. Recently I was driving to work (only 4 mile trip) and it started coughing/sputtering something fierce and the cab started to smell like antifreeze. The power brakes stopped working and the heater quit blowing. I got into the parking lot at work and it continued to cough/sputter for a good 2 minutes before it finally choked and quit. 4 hrs later going home it ran perfect.

    This cough/sputter episode has happened 3 or 4 times in the last month or so and I need to figure out what is going on. I maintain it regularly, there is pleny of coolant and I can see no evidence of anything major happening under the hood.

    The only thing I can think of is that about 2 months prior to the first incident, the idler pulley broke, which broke the serp. belt, which means I drove it at most 4 miles with none of the belt driven components working.

    I am at a loss(not being any sort of mechanic) and I dont want to go to a mechanic not knowing anything about my situation....any help would be greatly appreciated

    I'm curious about how many more miles I can expect before I have issues? I am having Racaro Seats installed because the standard seats were uncomfortable for long hauls. I thought about a new truck, but like the looks of my truck, it has served me well AND it is paid for, so a no brainer for me! Now I am excited about customizing. We recently put in a Rhino bed liner and sound system...any more ideas? How about maintenance??? Last major 125k and I do oil changes every3k.

    I'm a babyboomer female that loves to garden and golf...I am also happily married, so I'm only interested in S10 conversations - not pickup!

    :sick: I got a '93 Blazer with 166k miles. It has been running very well until recently when it started idling at 3500-4500 rpms. It had the fuel injectors and ICM changed. Please help. :sick:

    I have a 89 S10 Blazer 4X4. I changed the fuel pump because of low pressure and fine now. I changed the throttle body gasket. I get codes for all sensors and some that don't exist. fixed 2 computer wires and also replaced computer. It idles at 1000 and immediatly drops to 500 w/check engine light on and immediately idles back up w/light off. This is continuous. I accelerate and it sputters and have to press the gas repetitively and then finally goes. When it drops below 2000 you have to do it again. After about 15-20 min it may straighten out and be fine and then it will do it again when it's cold. Sometimes it will just start again when it's warm. It acts like a Mass Air Flow sensor but I can't find it nor do any parts stores list one. I am about to try the Idle Air Control Valve. Any suggestions?? Thanks :sick:
  • qamarqamar Member Posts: 2
    Its not the AC water pipes being clogged. There is air in your water system. Pl flush the old cooalnt specially when the Dexcool is inside it. Replace it with any Green Coolant available in the market. Also take out the thermostate valve out when you are flushing the water out of your system. Once you are funished remember to keep the raditor reserviour bootle full. Last of all if your truck is still with the original GM raditor cap, change it with any good raditor cap. the origianl cap has got the capacity to take air, thus resulting in guggling sound from the passenger side of the truck.
    Try it up and keep us posted. Best of luck

    the other day i took my tbu apart tring to find out why my 1989 4.3l v6 was flooding itself and stalling out on me, i think i figured out the problems.

    1. the injectors were spilling fuel even when the vehicle was turned off.
    2. when i opened the throttle body, the diaphram spring whas completely broken in half, this creates a problem, because when the diaphram doesnt have a spring, the truck wont run at the correct fuel pressre.

    the real reason i posted on this forum is because i was curious as to where i would find this spring. is it a dealer part, because napa doesnt carry it, and it doesnt come in the tbu repair kit. any info would be extremely helpful

    Hi,
    I have a 99 Chevy S-10 Blazer 4x4. I'm getting a loud humming or whinning noise coming from the front end. I thought it was coming from the engine, but when I stop and put it in neutral it goes away. Its only when i'm in gear. I just had the electrical switch that switches from 2x4 to 4x4 replaced. Any Ideas what the noise is. I'm thinking its something with the drive shaft or 4x4. It makes the same sound weather its in 2x4 or 4x4.

    I recently had to remove the head from my 97 S-10 2.2 Pick up because of stripped out spark plug holes. We were able to retap the the threads and do some major cleaning. After putting all back together we have run into a misfire issue. The truck runs great at driving speeds but the idle is all wrong. Though we were cautious when removing and replacing the spark plug wires, I am afraid that one may be crossed. Does anyone know a place on the net that I can find the spark plug wire routing for this truck. Any help would be greatly appreciated.

    93 S-10 Blazer Transmission help! I just replaced the motor in my 1993 chevy s-10 blazer 4x4 with the 4.3L Vortec ( threw a piston thru old oil pan) when i removed everything the transmission was running GREAT! My only problem, obviously, was the engine was blown... well... since i put it all back together the Motor is running great! but it seems my transmission does not want to shift into overdrive! anyone know what this is? Do i need to have my truck hooked to a diagnostic computer to reset anything? After i put the motor in, I did start the truck without the transmission in it. All I did to the transmission was change the transmission filter. I believe the transmission I have has the electronic "kick-down" It has a electrical connection on the passenger side of the transmission (i am not sure which one this transmission is) I will post a pic of the connector. CAN ANYONE HELP? PLEASE!!!!! I am moving to West Virginia soon and it is a long drive to make going 50mph cause it wont shift into overdrive!

    Anyway... here is the pic of the connection (if it works) or msg me and i will email it to you)

    I think I have the same problem with some differences. It also appears that others in this forum have some of the same problems. My 1995 S-10 has 176k on it an about three weeks ago it started to sput like low fuel but I had 3/4 of a tank. Trying to keep driving it started to heavy duty stall and then back fire through the pipe. Re-starting it, I thought it would shake the truck apart with back fires and rough running. I thought it was a major problem and stopped and called the tow truck. After about an hour, I helped the tow truck guy and drove it part way up the ramp. This surprised me that it would move at all and it was smooth running. At the dealer they could not find a problem and it ran fine. The mechanic drove it all day with no problems showing up and no error codes. It has been running fine now for the three weeks, about 500 miles. Then yesterday it did it again. Same scenario, started by popping and stalling, a little at first and getting worse. Finally, getting so bad that I had to stop and even afraid to take it into traffic. I let it cool for about 30 mins and it ran but rough. Stopped and let it cool for an hour and it ran all the way home ( approx. 20 miles)(after dark and it was cool) I think I detect a little rough running. I am beginning to think it is heat dependent and it may be one of the computers. I stopped at the local parts place and they pulled up the ignition module that's in the distributor and the main computer. I can replace both for about $400 which is a far cry for what the dealer wants. Am I thinking right here? Does this sound like an answer for some of these other problems in the forum like hard starting and running rough? Which computer is the one that should be replaced?

    I just bought a 1988 Chevy S-10 with a 2.5 liter 5 speed. My service engine light is coming on every once in a while when I accelerate. I got to looking at the sensor and all that and I found that the knock sensor's wires are cut and that's why my service engine light is coming on. Can anyone tell me where these wires hook up to?

    My, truck goes dead when I turn a corner, could my fuel pump be going bad?
  • drew6drew6 Member Posts: 3

    I had that problem in my truck, I jacked up the rear end and listened to it.
  • jaazjaaz Member Posts: 1
    I have a 96 S-10 4.3L.. When i bought it about 8yrs ago I bought a Haynes Service Manual. They only cost about $15.00. This manual pretty much walks you through any problems you may run across. Plus it has saved me a couple thousand dollars by keeping my S-10 out of the shop. The distributor and plugs should be stamped on the engine? Im removing my heads now due to water/oil mixture and everything is labeled in so way. hope this helps.
  • drummomdrummom Member Posts: 1
    We are looking at purchasing a 1998 Chevy S-10, 5 speed, 4 cylinder. The vehicle that we have found has 170,000 miles on it but appears to be in excellent physical condition both inside and out. It drives beautifully and nothing is leaking and no electrical smell from the engine. The only negative factor is the mileage. Anyone out there driven an S-10 for this many miles? If so, did you have a lot of problems? We only plan to drive it in town, not too many miles per year. Any thoughts would be appreciated!

    Hello..I have a 97 S-10 4.3 that I bought new. It just turned over 60,000 miles. My problem is...I am getting a "random misfire code'" 0300 per OBD. It almost feels as if I bought some bad gas it stutters so much. I have replaced the distributor cap,rotor button, plug wires, plugs, coil,and coil modulator to no avail. The fuel pump is about a year old. Marathon admitted to some bad gas about a year ago that caused many people to have fuel gauge problems. I had the same prior to their annoucement so I replaced fuel pump and sender. I also have replaced the fuel filter and pcv valved as well. Geez reading this makes me want a new truck..LOL..I change the oil every 3000 miles and also add a can of fuel injector cleaner. The dealer repaired an oil leak a month ago (oil pan gasket) and I have had this miss ever since. No other OBD codes on this at all. The dealer as well as another shop could not find a thing. They claimed the fuel pressure was correct as well. But I still have this misfire code. Any ideas or help on this would be appreciated. Feel free to e-mail me with possible solutions. Thanks....

    I have a 98 chevy blazer with 160k on it that has been having an overheatin problem. its been running on the hot side from 210-235. a few weeks ago i replaced the thermostat and the problem continued. then i replaced the radiator and while bleeding the coolant it started to run close to 260 so i shut it off. What else could be causeing my overheating problem?

  • blazer5blazer5 Member Posts: 5
    I recently had a valve job and replaced the heads myself. I also replaced the spark plugs and wires, cap/rotor, O2 sensor, Cat/muffler/pipes, and all filters. When I tried to start it, it backed fired and would not start. Could I have installed the Distributor 180 degrees off, or is their some other problem to blame? Can anyone help with this problem? Thanks!
  • ozzzy12002ozzzy12002 Member Posts: 2
    if you figure out what the problem was to the fuel pump powering on when it wants to please let us know,i for one have the exact problem, if i drive my 93 blazer for a while ,the fuel pump wont get power until the truck has cooled off-frustrating - thanks in advance :shades:
  • bikebike Member Posts: 2
    I just purchased a 2000 S10 4X4 with 4.3 automatic and the gas mileage is something else, I get about 60 miles to a 1/4 tank of gas in town. Anyone, is that normal or what, it has 93000 mi.

    Thank You

    1994 S-10 Blazer with 159K + miles, 4.3L Vortec 4x2, began stalling and then shut off. Pass experience led to the replacement of CMFI and EGR valve (4 yrs ago), now have changed the CMFI again thinking to correct problem. Still runs rough where you have to step on gas to open throttle. Exhaust smells gas rich. GM code reader gives 22 and 34 error code. Sensors: MAP, TPS, MAF, etc...
    Does anyone have any suggestions? Experienced this problem before themselves? Please help.... :sick:
  • ltc98mdltc98md Member Posts: 1
    Starting in Feb of this year, my right headlight went dim. I live in a mid-Atlantic state in the mtns where the state road crews love salt to melt the snow - so, lots of rust on the frame, etc. I figured the ground was bad on the headlight on that side, but I'm not so sure. About the same time this happened, my fan switch burned up. Switch has since been replaced. I've tried grounding headlight directly to battery, no luck. My 16 year old son (taking auto tech in school) says it's the multi-purpose switch on the column. I can't believe that this switch could screw up a headlight.
    Anyone with suggestions, I'd appreciate some help. :confuse:

    I think I need to change the Plugs on my 98 Blazer. It will ride fine, and then all of a sudden, the 'power' will cut out for about a second, and then it will pick up again. Also when I'm just idling, it feels like it wants to die. Is this a definite spark plug issue, or should I be looking for something else.

    Also I am experiencing A/C problems. I will turn the air on, and the light will flash and nothing will happen. I added refrigerant to it and nothing will happen. There doesn't seem to be any leaks. Is it just low refrigerant pressure, a compressor problem or what??

    I have a 1992 S10 Blazer; 4.3 liter engine; 4WD; throttle body fuel injection, 150,000 mi. The oil filter is mounted on the inside left front over the wheel well. From this there is a hose assembly that mounts to the under side of the engine at the left side. It appears difficult/impossible to disassemble and remove the hose at the engine end. [My compliments to the design engineer] However there is some other component to which the hose assembly is attached. This part is inserted into the engine and appears easier to remove to facilitate replacing the hoses. I don't know what I will find if I take out this part. Anyone have experience doing this? Hints, suggestions, or caveats will be appreciated. There is only the one pair of hoses. There is no second pair going to the radiator from the engine.

    Are you for real? Where did you get the torque specs when you put the head back on? Bet you didn't torque anything. I can't believe you can't figure it out on your own. How many days are you gonna wait for a reply? It's a 2.2 whoopdie do. Buy a book if you can't figure out where to get the "firing order". Thats what you should have done before you took the head off. When you get the book, go to the back; it's called an index, look in the "f" section for firing order, it will give you a page number. Remember: You have the 2.2. :P

    I have an 01 Blazer. The problem started when we opened the back hatch to put a bicycle in the back. Ever since then the inside dome lights stay on ALL THE TIME. We checked the door switches and they are ok. We have checked all the fuses... they are OK. If we rotate the manual switch (dimmer) we can hear the relay (under the dash) clicking. But they lights stay on anyway, Took it to the Chevy dealer and their diagnostics show no problems. We have the fuse out so the lights won't drain the battery. Any help would be greatly appreciated.

    I know it seems kinda obvious,Clutch in the fan could be bad.I bent a bunch of fins on my radiator and she got hot fixed about half of em and she cooled right down.

    My blazer has been eatin up upper front ball joints.
    I removed my sway bar in the front cause of all the off road stuff i do and only have one CV joint where it belongs in the front,just takin up space front diff is toast.
    Anyone else had same problems?
    I know most have folks have everything intact in the front, Gotta understand what kinda driving i do.Rough is a little understated!!
    just wondering about the uppers.
    Thanks
  • dosceoladosceola Member Posts: 4
    That is about my mileage on my 99 same motor, i just turned 100.000 and i have had it for 2+ yrs now.
    Sucks really, check your clutch on your fan if clutch is bad it tends to drag down the power i use a k&n filter and nothing changed, thought it would have gotten worse but it did'nt.
    Air compressor on AC could be draining it also,
    Heavy truck with a small motor and aero dynamic as a brick!
  • fbaysingerfbaysinger Member Posts: 1
    I have a similar problem with a 1999 Chevrolet Astro, misses on idle, when hot, sounds like a snap (similar to spark gap), but no visible breaks in insulation, I have 75K on engine, appears to be no power loss, just the miss at Idle. Sure hope someone can find the solution to your problem as I am sure that is partly my problem..... Good Luck - Mr Goodwrench where are you??
  • dleebridgesdleebridges Member Posts: 2
    Your EGR valve is probably malfuctioning...it's not bad just dirty... clean it out and ask your parts store to get a special gasket from TOMMCO that has a tungsten screen sandwiched between two gaskets... it would probably be a good idea to remove the intake an give it a good cleaning. The carbon build-up is bad in these engines. I fought this problem for three months.
  • dleebridgesdleebridges Member Posts: 2
    EGR passages are blocked ... remove and clean EGR Valve, clean intake manifold of carbon and replace gasket with one from TOMCO Inc. part # 2-1357 (Klean Screen Gasket) ...actualy two gaskets with a tungsten screen in between. It is supposed to get so hot it burns any carbon before it gets in the valve...

    Good luck...

    The service enging light came on in our S10 right as it hit 60K, but went back off at 60,001. Our mechanic says he doesn't think the early 90s models are made to come on for schedualed maintanence. The only cause for concern is that we had a '94 blazer in which the light came on and wnet back off immediately, but later in the day had a major breakdown. Does anyone know if the light should just come on for maintanence and if so, shouldn't it stay on longer than 1 mile. Thanks for any help. :confuse:

    my blazer started to become a problem when i try to rev up on go...it doesn't want to die it just wants to kinda stay in place...it has to rev up slow in order to go....if you give it gas it won't go as fast as it should...any suggestions?
  • hard2fixhard2fix Member Posts: 1
    i had the same thing .the fix is to use a dremel cut off wheel on the rubber hose to metal line connection .it sort of looks like a barrel shape where they meet .don't cut into the hose just through the barrel shaped metal fitting .to get to where they meet you need to unbolt the skid plate which should be plastic .there is a half inch bolt that un bolts from the oil block adapter that bolts to the underside of the block .all of the blolts are 1/2 inch .you may even have to unbolt the flywheel plate which has 3 bolts holding it on mine did anyway .hope this helps this the way i did mine .there wasn't a thing about repairing it in my manual

    '94 S10 Blazer (150k)

    My brakes intermittently get very hard, with no stopping power. Sometimes I can push through this, but other times I have to let it up completely and try again. Usually the second or third time after I let it up, it depresses fully and normally.

    The problem only occurs after I have been driving for awhile. The first 15 minutes each time I drive it are usually fine, but then the problem gets worse the longer I go. Eventually the ABS and brake warning lights will come on, but that takes a long time, and I've only had that happen once or twice.

    Other symptoms include a low and soft grinding noise when it happens, and hot front rims after I've been driving.

    Front calipers and pads are new, and the rear drums are new.

    I've been doing okay going back and forth from work, but I have to drive half-way across the country in a couple weeks. Any insight would be greatly appreciated.
  • newblazerkidnewblazerkid Member Posts: 6
    Same problem from #100...

    I just put my front end up and noticed that the driver's side front wheel doesn't spin as freely as the passenger's side front. I get at least a full revolution when I spin the passenger's side wheel, and at most 1/8th of a revolution on the driver's side.
  • dhatterdhatter Member Posts: 1
    1. I just bought a 93 S-10 Blazer knowing the 4WD doesn't work (got a killer deal!). When you press the 4hi or 4lo switch you can hear something engage/disengage under the truck. If that much seems to be working, where could the problem be? I'm sure the 4WD doesn't work because I made them put it on a lift to verify if works or not.

    2. Can the analog instrument cluster be switched with the digital one? What modifications are necessary to make it happen?
  • warloc72warloc72 Member Posts: 1
    I'm having the same promblem with my 04' Blazer. When I run the AC I hear this Blowing Noise and I start loosing power like the tranny is slipping or something. The dealer told me that it's the fan blowing 3X's faster under extreme heat and that the lack of power could be caused by low fuel gade and clogged fuel filter. I don't think so. When I first bought this car I had to be very carful not to spin the tires, now the tires might spin on a wet road. I'll try the fuel filter to see what happens.
