    Ok guys i just drove my wifes 1999 Chevy Venture van from fredericktown to mtvernon about 15miles or less. Get to town and stop at the first light and the van is not running good. Felt like it was missing reallly bad and shaking. so we hit the store quick then stop to pick up pizza. Not wanting to run the van i park it run in come back out 5 to 10min later and it won't start. Finally starts and BIG cloud of whitish gray smoke rolls out. We head home van running like crap when ever you stop. Get almost home a block and the temp goes way up was fine all the way home. Pull in the drive and shut her down. Went back out and she starts but get whitish smoke for cpl sec and smells after you shut it down almost like an electrical burn smell if you have ever smelled that. Engine light on and flashing. Van only has 60k miles on it oil always changed driven by wife local in town driving. Any ideas or thoughts.

    got bad feeling its head gaskets or something whats this cost iam considering putting a remanufactured engine in. As the cost of head work is expensive.
  • From the description, I would also say "Head Gasket.' I have a 2000 Chevy venture and the Head Gasket is still good. But I do have an old 1985 Pontiac Acadian where I had White Smoke coming out of the tail pipe and black sludge in the Air filter where the Oil and Antifreeze combined. It ran really lousy too. In the end it was a head gasket.
  • Cross posted under Idling and Stalling problems.

    I have a 97 Venture with 144K miles on it. I have recently replaced:

    serpentine belt
    tension pulley
    harmonic balancer
    water pump
    MAF sensor
    Throttle positioning sensor
    ECM (a year ago)

    The serpentine belt kept coming off, finally narrowed that problem down to the harmonic balancer wobbling, which threw out the tension pulley. Also replaced the water pump, in case this was also a problem. After doing that, I found some water leaks, and tore the engine down to the intake manifold, found a few bad hoses and connectors. Then after putting everything back together, the van is now stalling when idling (sometimes) or coming to a stop (sometimes). It doesn't matter if the engine is warm or cold. I've gone back through and checked all the vacuum hoses. Everything looks okay.

    The "Check engine light" was on , the codes came up as P0102 and P1441. P0102 was the Mass Air Flow sensor, so I put on one of those. Then reset the codes, drove it around, stalling again, check light comes, check the codes, same as before. Faulty MAF?

    Go back to auto parts, get another one. Same routine. Still stalls. My buddy at the auto parts gives me a new MAP sensor to try and see if this is also a propblem. It's not. So I go back home, and fiddle around with all the connections, look at the wiring harness and can't find anything wrong. Some research on the internet and the Chilton's manual suggested a new Throttle Positioning sensor. So this morning I put on one of those.

    My wife takes it for a test drive, after letting it idle for about twenty minutes in the drivewayy. Seems to run fine. We stopped and started with no trouble and go back home. Then later this evening, she takes it out and guess what? IT STALLS!!!!!!!

    Does anybody have any idea what else is wrong here? What else should I look at, how can I test for other problems? I read something about the brake booster. Anybody know anything about a faulty brake booster causing a stalling problem? I've already thrown several hundred dollars at this and really don't want to waste another 200-300 dollars on somemthing that may not even be the problem.

    Thanks in advance and sorry so long!

    I have the same "problem" Noticed it first on the freeway behind trucks and when passing. It is definitely a turbulence issue I believe. Had it on my 98 Venture and now on my 2005.

    Boga228,
    thanks.....i started having the coolant flushed/changed every year...last time had it pressure tested, every thing still good.....
    i'll start checking the oil for coolant also.......
    it's a shame these cars are not better quality engine/tranny..they have a lot of room, ok gas mileage, and easy to drive...
    had the van detailed out the other day for wife....looked brand new, like the day we drove it off from the dealer...
    hope we get 6 more years out of it....

    I need some help. I have problems with my Ventures electrical system I think. When I put the van in gear I get odd reaction when I step on the brake or use the turn signals. For example when I step on the brakes the bake up lights come on very dim. When I use the turn signal the brake parking and back up lights "strobe". It does not seem to exhibit these problems while in park. I am at a loss. Any suggestions.

    My rear window washer on my 98 Venture has not worked in a few months. Not sure if it's a pump or plugged line or perhaps pinched off somewhere. Anyone with similar problem, would aprrieciate any info. Thank you.
  • Our 98 Venture was doing very similar stalling while driving along. It turned out to be a crummy electrical connector to the fuel pump. This connector was under the body of the van, near the fuel filter. (if memory serves me correctly) I cleaned up the contacts, and applied dielectric grease to keep water and dirt out. That was 2 years ago, so far, so good.

  • Our 98 has a similar problem. But first, check the fluid level, the rear pump runs dry more quickly, as they share the same resevoir, and it's mounted higher. Otherwise, ours was caused by the line dropping off the connector at the fluid reservoir. If you try washing the rear window, and notice a puddle on the ground at the front passenger side, that's your problem. It's hard to reach, but can easily be slid back on. A zip tie has helped prevent this from recuuring regularly.
  • Our 2001 venture has extended warranty which expires this August. The van is running fine at the moment. We have had the head gasket replaced and some AC work done under warranty.

    I want to get as much fixed under warranty as I can. Should I bring it in to the dealer for an inspection or what?? How much help would a dealer be it this situation?

    Thanks for any suggestions

    I have a Chevy Venture minivan. Somebody sit in 3rd row spilled a cup of coffee on the floor. 4 hours letter, my engine light got on, and then, the fuel gage went to empty. A quick check by mechanic (with computer code) told
    me that both the fuel level sensor and fuel pressure sensor reading were wrong. An estimated cost for replacement may exceed 400 bucks. I suspect it's just
    a minor problem on connection contaminated by the damn coffee. Whoever know where I can get the wiring diagram of 99' Chevy Venture, so that I can do more detailed check and save that 400 bucks?

    The low coolant light on my 2000 chevy venture(50K)has come on permanently. The coolant level is good. If its a sensor, where exactly is it located? Could not find any reference book at the library with such detailed info. Although the level is fine, I sometimes can smell antifreeze when I get out of the car. Other than this I've never had a problem with
    this van. Except they could have put some arm rests on the value van.

    The sensor is about 2" below the raditor cap. you should be able to see the wire connector on the side also. Smell of coolant could be in a lot of places, it cound be a leak around the intake manifold or the water pump with that kind of mileage.

    Try the Haynes book not much detail but helpful, for sure the dealer book has it becuase i have one. you can purchase it at www.helm.com for about 100.00

    I have a 2003 venture with 139000 miles on it. The only work I have had 2 have done is the relay switch to the cooling fan for the radiator and the relay for the blower fan. I purchased the van when it had 93000 miles on it from a company, it was a salesmans van. I drive about 6000 miles a month, change the oil every month, I use full synthetic, change the brake fluid, powering steering fluid, transfluid and coolant about every 6 months, about the same on tune-ups also....but is just regular maintenace 2 me. :)

    the 4th gear shift solenoid may be gone with the hood open key on engine off stand in front of van and listen for solenoid clicking noise from trans noise will be coming from the area under the air filter housing

    Used a Snap On Scanner on the tranny, Solnoid good. Pretty sure friction plates worn. thanks

    This may be too late but I just replaced mine. $85.00 motor from Nappa and 20 minutes of work - taking my time.

    I have a 1999 Venture with 120,000 miles on it. When I am in gear and at a stop with my foot on the brake, my engine vibrates and shakes the whole car. It's loud inside the car, but you can't hear it outside the car. It's not the motor mounts, those are still good. It's gotten so bad that when I am at a stop, I put my car in neutral and this quiets the car down. (It's also not the muffler). Anyone else have this problem? Thanks :shades:

    Maybe the idle RPM is set too high. If you have a tach, what is this RPM?
  • Hello, just found this wonderful forum. Has already helped me troubleshoot some issues. My rear wiper isn't working on my 2000 venture. It goes about 1/2 a rotation then stops and makes the loudest grinding noise. I'm pretty much convinced I need to replace the motor but for the life of me can't seem to figure out how to get to the motor, can't find a way to remove the hatch's inside door panel to get to it. Please Help!
  • Have owned my 2000 venture since it had 30K on it, it now has 124. Since I first bought the van the headlights and interior (dash and dome) lights flicker in time to the engine RPM. If I rev the motor the flicker frequency increases. Never had any charging problems but think that this may be the voltage reg in the alternator. Any help is appreciated, Thanks.
  • 2000 Venture, 124K miles. Low coolant level light is on constantly even though level is fine. I do get a slight coolant smell when the motor gets hot. No visible leaks, had cooling system pressure checked and it checks good. While idleing when engine is hot the temp jumps way up but then starts back down then kind of oscillates up and down (this is very troublesome on the interstate in bad traffic). Once back up to speed the engine cools back down quickly. I've have not yet replaced intake manifold gaskets and still run Dexcool. Could this be the culprit for these symptoms. Didn't know maifold gaskets were such an issue till I found this forum. Maybe I should replace them and switch to universal coolant. Any suggestions are appreciated. Thanks.
  • ronsmith38ronsmith38 Posts: 228
    I think there is a TSB on this problem. It has to do with a grounding lug. You can search this and the other GM Van forums for info on this.
  • I have a 99 Venture w/ 118K miles, am getting a coolant leak off the bottom of the engine, can either trace it to the thermostat housing or the water pump? Anybody had problems before? :confuse:
  • snomansnoman Posts: 1
    With 124K on the intake gaskets I can almost guarantee that is your problem. Felpro makes a new gasket that is metal and rubber instead of plastic. They work great.
  • Well I am new to this discussion and I am hoping and praying someone on here can help me. Today my daughter and I were driving in my 97 chevy venture with less than 70,000 miles on it. Weathers not to hot and we weren't driving very fast and we didn't go that far when Bam!!! I thought I had blown a tire and stop the car to take a look! Well it wasn't a tire it was the engine. So Luckly for me we had less than 4 miles to go and I put on my hazards and hobbeled her home. I don't smell anything burning -nothing is leaking - oils full. I have no idea what this could be. DOES ANYONE HAVE ANY IDEADS??

    PLEASE HELP!!
