#5 of 132 Bad Thermostat by smasterman

Nov 07, 2007 (4:21 pm)

I have a 2002 CX (86,000 mi) that has a temp gauge that has gone out of control. On an 11 mile trip it went from C to H with the overheat light going off, back toward C and back again 4 times within the trip. No radiator / coolant leaks, but I know it's not good for the engine. I figured bad thermostat, and had that replaced. It didn't fix the problem. Will the thermostat take a little time to "seat" or something? Also, no heat coming into the car when this stuff happens. Just great for the upcoming Cleveland winter. Have any of you had this happen, and what did you do to fix it?
 
Thanks,
SM

From what you discribe it sounds like air in the system and it needs to be purged via bleed screws. The thermostat should not take any time to work properly.

I have a 2002 Rendevous CX and I had a new transmittion put in in June 2006, when I collected the vehicle and paid the $2600 bill I noticed that the service light was on....after more 3 visits to the dealership I was told it was the BMO....my interior lights don't work or flash on and off, and periodically all the dashboard lights and indicators fail.....also my heater/blower only works now on high....are these things anyone else has had issues with? and are they things I can fix myself?
I would appreciate any feedback....

Well, we took it to a shop and had it flushed and filled with new anti freeze, and a new thermostat. Something else we had done was when we had it flushed and refilled, we did not use the Dex-Cool anti-freeze. We had if refilled with regular anti-freeze. The Dex-Cool has some faults to it. It will eat the seals out of the engine and then you will see leaks.
I hope this helps out in any way.

Sounds like an air problem to me to. Have recently changed your air filter by chance? If the air mass system isn't set up and everything all lined up perfectly, the car does have a tendency to run warmer. At least that is what took my a long time to find out. From the day that I replaced the stock air filter with a new K&N air filter, I had problems until I took the time to really be careful putting everything back together. By the way, the K&N filter will give you a lot more boost to.

#13 of 132 2005 Rendezvous Head Gasket by mrfsra

My 2005 just blew a head gasket 58,000 miles. I don't tow or any other unusual conditions. Isn't a $2,000 engine repair unusual for this mileage? Does GM ever pay for unusual repairs out of warranty?

i have an 2002 and i struggled with various problems until it was very obvious that i had 2 blown head gaskets. this is a very sensitve motor or a poor design....look for another motor, it'll be cheaper.
