#22 of 26 heating and cooling by caperguy4u Jan 04, 2009 (5:18 am)
I have a 1997 venture that is heating up on the gauge and sometimes breaks loose and i will get some heat coming out of the heat vents but most times just cold air. I had the thermostat replaced along with heat sensor and radiator flushed. No sign of water in oil and no white smike from exhaust.

Replying to: davis911s (Dec 19, 2008 1:48 pm) PO172 is engine running too rich   PO300 is random misfires detected.   Sounds like a bad ignition control module to me or fuel system issue (injector or system pressure)   I would start by checking those 2 areas in that order   Good Luck...

Replying to: davis911s (Dec 19, 2008 1:48 pm) Troubleshooting the Venture engine is not simple a matter of changing a few components. The factory service manual is several hundred pages long and tough to read. I would first suspect a blown intake manifold gasket or cylinder head gasket(s). If you have oil pressure problems, loss of coolant, and/or overheating that is where I would go before the computer system. I landed up changing out my engine with a junkyard engine. Runs fine now. If you need more email me direct: lloydballardhotmail.com.

Replying to: caperguy4u (Jan 04, 2009 5:18 am) Had the same problem. Ended up being a head gasket. Lots of money to fix. I used STEEL SEAL cost me $80.00 and it is still working 2 months later. I average about 400 miles per week on my 2000 Venture. I had no signs of water in coolent or blowing smoke just constant high pressure in cooling system. Hope this helps.

Replying to: rkarch (Jan 05, 2009 10:04 am) Could you clarify your symptoms? Think you meant to say no oil in coolant or vise versa? Also what do you mean by high pressure in cooling system? I think you mean the coolant was boiling over? I am tucking your suggestion to use Steel Seal away incase my engine acts up again. It appears to have a small leak that may be triggering a check engine light for a catylatic converter problem.
