Replying to: fleastiff (Jun 23, 2008 8:52 am) Sounds like an internal leak...lower intake manifold gaskets or head gasket possibly...unfortunately a common failure...   I bet the hot metal smell is the cat converter as its getting really hot due to the misfire issue...

Replying to: 442dude (Jun 30, 2008 4:56 am) I'mmm baaackkkk 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..

Can only get like $400.00 or a little more if you can prove over 2k in bills but what the heck better than nothing I guess. Replies to this message: rockbazz (Jul 11, 2008 6:23 pm)

#59 of 109 2003 Chevy Venture jumps and stalls by mojoloco Jul 21, 2008 (5:10 pm)
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? Replies to this message: davet_1961 (Jul 22, 2008 3:20 am)

Replying to: mojoloco (Jul 21, 2008 5:10 pm) Well, my venture is a 98 model and wasn't making the sound you describe, it was shaking and stalling, losing coolant and idling roughly. If your engine has EVER overheated, I'd suggest having the compression tested to see if one of the head gaskets is blown. Mine blew a head gasket, I had it repaired (about $800 at my local mechanic, probably a $1400 job elsewhere) and now it runs perfectly.

I have had the waterpump, thermostst and headgasket replaced and the engine is still overheating. When I run the heat it does not overheat but the heat will go out and it only blows cold air and the engine will overheat. the van has about 145,000 miles on it. any suggestions welcomed Replies to this message: 442dude (Jan 10, 2009 10:11 am)

Replying to: bookmark1 (Jan 10, 2009 3:23 am) I know you just had your thermostat replaced but the symptoms you describe would point to a faulty thermostat. The thermostats on the Venture are really sensitive to oil contamination. If there were traces of oil in the system related to changing the head gasket and they didn't get them all out by flushing the system, the new thermostat may have been ruined and may need to be replaced again after the system is flushed.   Are you losing antifreeze? The intake manifold gaskets are always suspect on the 3.4 but they might have replaced that when they replaced your head gasket.   Something else to check: check to see that the air was bled out of the cooling system. There are 2 air bleeders, one by the waterpump and one near the thermostat housing. They need to be opened when you're refilling the system. Maybe you've got some air in there and the waterpump is getting airbound?   Just some thoughts...Good Luck
#64 of 109 2005 Venture Heating Problems by JimNewton Jan 10, 2009 (9:36 pm)
Can someone help me figure this out? I see there are many heating problems with these Ventures. I am in Vancouver, BC have a 2005 Chevy Venture with 115,000 kms - since Christmas I have been getting some really weird stuff happening - was on the way to my sisters when my daughter had to go to the bathroom - let the van idle and then noticed that the temp had gotten very hot - almost to the red or maybe even in it. Stopped at my sisters for Christmas eve, van would have cooled down, but instead when I turned it on again the needle went past the red and around the corner! No signs of fluid in the oil or low water, or overheating. Maybe a weird smell, but the whole van has been smelling lately due to the wet snowy much we have been having. Just tonight we were driving for an hour or so and the temp was perfectly low, me eyes were glued to it. But I turned the van ignition back on after a couple of minutes of being parked and the needle suddenly went full hot to the point it was clicking because it couldn't get any hotter!!   Any ideas?
