- I have a 02 Venture I have went through the steps that GMMerlin has posted.
http://www.automotiveforums.com/vbulletin/showthread.php?t=331229 and the engine is still getting hot and I am having a problem getting all of the air out of the cooling system.
I will describe the exact scenerio here -
1. My wife noticed the engine temp was getting hotter than normal and the heater was blowing cold "intermittent heat".
2. checked the coolant level and it seemed to be down a bit maybe a quart +/-. we topped it off and engine still got hot and no heater.
3. well I figured it must be a thermostat problem, replaced it after a few hours of manual labor, still same situation. surely the new stat couldn't be bad, well I replaced it again with another thermostat and this time I went all out and replaced the waterpump thinking the coolant wasn't being circulated. LOL just more wasted money, Still same problem.
4. That is when I went to the web and found this site. Everything I found about the van overheating pointed to the intake manifold gasket, So yes that was next, After all of the hours I had already put in to this engine in the past few days I wasn't going to give up without a fight.
5. In went the new intake manifold gasket and another flush and fill of coolant and an oil change. It is now Day 5 of working on the van and this thing is driving me nuts.
6. This is where I will beg for guidance from the experts. HELP
I have no idea how to purge the air out of this system, I think I have followed your steps properly and it is still getting hot.
7. This morning when I started the engine the engine sputtered and the check engine light started flashing at me so I shut it off and call my buddy with a computer to hook to it, it said "misfire at cylinder 1"
when he started the engine to check the code it ran fine (no sputtering)
he seems to think it may possibly be a head gasket.
I also noticed that the fans dont kick on, except when the A/C is on one fan will kick on.
I think there is still air in the system! if so can someone please post detailed instructions on how to purge the air from the system. Is there a chance that it is a head gasket or some other problem, if so what could it possibly be..
Thanks very much for your help,
