You are in the Chevy Venture
What is this discussion about?
Chevrolet Venture, Pontiac Montana, Oldsmobile Silhouette, Van

Ok I scanned the van
I got P0172 and P0300 codes. I then erased the codes and started the van for about 30 seconds and kept it running (gave gas)
The only code that came back was the P0300
What can be causing this?

1. Overheating on this is usually blown cylinder head gasket or the intake manifold. Many of us believe it is the Dexcool anti-freeze. It turns to brown mud (check the radiator cap and inside the opening it will usually be brown mud. The mud is acid that eats the gaskets. Google Dexcool problems and see for yourself, it resulted in class action lawsuit in California.
2. Cost to fix on a 2000 probably exceeds value of vehicle. If you go for the repair, you need to add in new radiator since the Dexcool clogs that up as well.
3. My advice to you is RUN, do not buy unless you have capability to repair yourself. I had same problem and landed up changing engines myself. If you decide to go that direction let me know, I have written a how to guide to assist.
4. As far as having problems related to the oil filler cap, that is one on me. Something else transpired like knocking the PCV valve out of the rocker cover.

#22 of 28 heating and cooling
Jan 04, 2009 (6:18 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.

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

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.

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.

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.

Russ23, I saw you mention that you had done a writeup on replacing the engine/rebuilding it in one of your other posts. I don't know if you still haunt these forums, but I'd love to hear what you ran into in doing this. I just picked up a 2001 Montana with a blown head gasket. I grew up on a farm, so I'm not terribly intimidated with pulling the engine, but it's nice to know what all needs to be looked at or even replaced.
Thanks in advance,
