Replying to: startingover (Jun 06, 2008 3:03 am) First things first...I'm not a mechanic unless there's some beer and a shade tree around...but I do have a Venture and I do work on it so I only reply to problems if I have experience with them...just wanted to be up front... That being said, I have 3 thoughts/suggestions: 1 - I don't think you've done any damage by driving it while the needle was just a tick above 1/2 way...its a little warmer than usual, but I don't think its a big deal. 2 - I wouldn't be surprised if changing the thermostat again would cure your problem...the new thermostat could have gotten messed up by all of the gunk that was in there before the radiator was flushed or even while/after it was flushed if it wasn't removed when the flushing was done. 3 - (and maybe less likely) After you refill the cooling system, there is a procedure to bleed out all of the air from the system. There are air bleeders by the thermostat housing and by the water pump which have to be opened to let all of the air out...perhaps this procedure was overlooked when the system was refilled? Good luck...let us know how you do... John

I've read through this blog and can offer this experience - the engine temp in my 2001 Venture has been fine for the last two years since having the intake manifold gasket replaced. I went as far as having the thermostat replaced but the problem came back. Dealer claimed to know squat and was completely clueless. A local mechanic new of the intake manifold gasket problem, found a small leak which went undetected due to evaporation and performed a pressure test which confirmed the problem. The van has been fine in that respect since. For the past two years the engine races in temps over 85 degrees. I posted this problem on the chevy board and opinion there is Idle Air Control valve. It's been 90 degrees plus in the NEast this past weekend and the van is racing again. The idle will reset sometimes when turning ignition off and on but its only a matter of time before it kicks up again. Last year I lost the small radiator hose and serp belt due in part to this excessive racing (71000 miles). Any insight into this problem is appreciated. I'll report back if replacing the IAC resolves this problem. On another note, I've had some goofy electrical problems with this van (fan control, rear AC vent door, stereo gets hot) but it does drive nice, has good pickup, gets good gas mileage and hauls a lot of gear - if you get a good one or can get past the BS, they're good vans. I have to keep it now - its worth nothing on trade-in! |

Replying to: 442dude (May 19, 2008 4:31 am) The symptoms are just like running out of gas. An hour later, started up fine. Going back to the dealer with the idea that these folks need to do some digging in their database for similar issues. Count on the fact that I'll be asking them about the crankshaft position sensor!.. this is nuts - and I'm going on a long trip in 2 weeks and I don't want to take this van until its fixed.. I recalled last night that the dealer did run into the van stalling at their place a few months back in the winter even!.. They had to push it back into the garage and repair. They said it was a bad connection on the fuel pump. Well, only because the Van cooled down did it start again. - I'll be reminding them of this incident and that what they thought was the problem, actually wasn't !.. Stay tuned ...

Replying to: 442dude (Jun 30, 2008 4:56 am)  I just got back from a 2 week travelling trip. Prior to the trip, the dealer installed a monitoring capture device that I could enable if I had the problem and get some info to take back.. unfortunately, I didn't have the problem.. I decided to pull the trigger and have the crankshaft sensor changed... I had to do something to see if it would resolve the problem.. All was looking good until my LAST stop for gas on the highway coming home.. it did it again ....arrggg......  I'll have to let them know that we can eliminate that component as the issue.. ..it really is just like I don't get fuel to start the thing up.. strange.. I'll keep you posted of any news.. thanks to fleastiff for the URL on that claim. I understand a similar case has occurred in the Province of Ontario so I'll be looking to see how that progresses.. Cheers

Replying to: startingover (Jul 07, 2008 8:24 am) A previous person posted that there was activity in one of the States. I'm in Ontario, Canada and I just recently heard about litigation that is up and coming.. Thanks! |

Hi, I'm a woman so of course I'm gonna try to explain with noises. It kind of jumps? or vibrates at a stop light, it stalls sometimes when starting up a hill but if I mash the gas it turns out ok and doesnt stop. sometimes it makes a wuwuwuwuwuw noise but fast like tires? also, advanced told me i needed a new battery so we put one in today, and it still acts the same. The suggestions I've gotten are : fuel pump, alternator wire and alternator..............from different people. Advanced said the alternator is fine. The battery still reads low voltage. Return Code : VCMMM - Starter test = normal, Charging system test = no problems , Any help please?
