Question about 1999 Chevrolet Venture

INTake replaced but still having issues

99 chev venture van- we have a coolent issue, we had a bad intake gasket which we have fixed, new water pump and thermostat. For the last 2 days the temp needle was not moving alot and if it did it was air pockets. TONIGHT drove it home(hwy) and the temp gage was all over the place. When it starts getting higher the heat from the blower turns cold and then all of the suddent a hick-up and the gage goes down and there is a burst of heat again,...the coolent level is fine and is not leaking. What more could this be???? Our temp gauge would show hot when sitting still when we drove it, it kept going all over the place. We replaced water pump intake gasket thermostat and we finally broke it down and the heads were cracked so we replaced them. Now when it sits and idles doesnt make a cound runs smooth. Soon as you drive it. It misses ALOT the more you run it, it seems like it runs a little smoother. But it still misses real bad. What can I do?

I'm betting that you already know the answer and are hoping that there is a quick easy cure you missed...
If you already ran this with the heater on high and system open, chances are there was no more air in the system. You do show symptoms of air (heater hot/cold) but, likely the system is getting exhaust in it Either the replacement heads are warped or had a crack in them that was missed.
Do a pressure test and then check the plugs for signs of water (coolant) on them. If you still think there may be air in the system, jack the corner nearest the fill neck up to get it higher than the rest of the system, and run it again with heat on full.that should get any air to migrate out (seeks highest point) If you have a shop you use, have them check cooling system for hydrocarbons that will verify if exhaust is getting in there.
This is an answer where I actually hope I'm wrong...I know how much "fun" it is to tear it all down again, and do not wish that on you. Check carefully and don't assume anything based on the previous problem. Treat this as a new problem and be sure everything is correct as you go.

It has an air pocket in there somewhere. You may need to get someone who can put a vacuum pump on the system to get the air out. Did you fill it up and use the bleeder screw? Not recommended, but you can run the vehicle and intermittantly crack the bleeder screw open and get more air out that way.

2003 Chevy Venture Warner Brothers Edition Mini Van 140,000 miles. Head gaskets blew yesterday. $2700 quoted to repair. Is it worth it to repair? What are other know issues with this model at this mileage...


what is the condition of the rest of the van? how does it ride, steer, shift and so on?
$2,700 is a lot less than replacing the whole van and you could end up buying someone elses headache if you go used..
if it ran really well before the gaskets went i would invest, if it had other issues i would trade it in

Coolent leak in m0tor. Not sure if it is the water pump or not. Is this a common issue for 97 siloette? How do I fix the problem?


It could be the water pump but the intake manifold gaskets are another common place for these vehicles to leak coolant. You'll have to fill and pressurize the cooling system to pinpoint the leak before determining how to fix it.

Just put new spark plugs in 97 buick lasabre. Car now starts and runs, but is blowing out white smoke. Is this blown head gaskets? Does it have anything to do with the fuel pump put on 3 weeks ago?


these cars have issues with coolent getting into the intake... headgaskets are not one of the issues . check plugs for coolent. upper plastic intake has coolent flow in to chambers if u will, and over time they get micro cracks and brittle ...lower intake manifold gaskets are plastic also. ..cyl. heads are cast iron not alluminum . lower intake manifold is alluminum and upper intake is plastic .. on my lesabre a plastic 90 degree elbow connected to the lower intake manifold to the heater hose housing. the belt tensioner is connected to this housing im refering to. not saying for sure, but if it is this is usually why...

Chevy Venture Overheating


Almost sounds like the same symptons as my van. Turns out the guage was not the problem. The van was in fact running hot because the electric radiator fans were not kicking in when the engine was hot. I replaced the relay switches for the fans. There are two of these in the fuse panel under the hood. There has been no problem with overheating since

99 venture leaking antifreeze


Your leak is most likely the intake gaskets. These are a real common problem on these motors because they are plastic.check the mating surfaces between the heads and intake for signs of antifreeze. If it is the intake get it fixed right away or it can leak internally and cause bearing damage. Also use felpros metal gaskets.
