pretty bad
cooling system problem
I have the same problem i was told on my 2000 gtp, have put coolant in several times in the past 3 mths I have over 180,000 miles and have spent only 2k on it in repairs so i have been happy I love the car but I dont want to put anything over $600 for the intake manifold gasket that went bad due to faulty Gm dex coolant and plastic parts. So I might attempt to do it my self this weekend.

This pontiac was a hand me down from a family member. It had roughly 88K on it when I took over it ( can't remember if I had to finish the pay off). Towards the spring of 05 if my memory serves me right. I had to change spark plugs, no big deal did it myself. Now after the tune up then started all the other major mechanical problems. Right about the 108 K mark low coolant light comes on. Did what everyone else has done too - added the coolant almost everyday, changed thermostat, hoses, water pump, and sensor. Now at the time it was during the middle of winter. A lot of the small repair garages were backed up with other work. I decided to take my POS to a dealer BIG MISTAKE. After their tech pressurize it no leaks. Then the tech said the intake gasket need replaced. I was under the impression that only 3.1 and 3.4 L had this problem. I was wrong. After $1,100 of their work plus my own work. The coolant problem was solved.
March 2010, low coolant light comes back on. WTF! after almost $1,500 later the damn light comes back on. Did the pressure check 5 times in my own garage found no leaks. However, heard some leaking from the intake elbow, no big deal right. Replaced that bastard. Still "low coolant light" comes back on. Took the car to a small repair shop had them pressure test it. They told me that there was a small leak in the radiator and would cost me $600+. Screw that, it wasn't a big leak because I put bars leak in it. Now the son of a b*tch is finally holding pressure. But wait the light continues to come on. Now if I replace the coolant sensor it will be the 4th or 5th sensor to be replaced.
I will not buy another Pontiac ever, I have roughly $1,800- $2,000 invested to keep this car running. Now my transmission is shifting hard too. GM should of had a recall on this problem, but no. Dicks.

A known issue for my vehicle. Wish I knew about it when I purchased the car. I am one of the lucky ones that didn't have engine damage done.
I suggest when you get your intake manifold gasket repaired that you also do the thermostat and a complete coolant flush since the engine will be opened up anyways.

Well My car had been over heating alot and i took it to our mechanic and he said it was a hole in the manifold or some crap like that and he said it would be 470 to fix! But now the water hasnt been leaking out lately but the damn temp is still goin up and now it is making a scratching noise in the air conditioner!!!!!!!!! The car is a big POS and i hate it ever since i got it , its just cost and arm and a leg to fix it.

This will be the second time in less than a year my car has had the same problem with oil leaking into the coolant. My ex warranty did not cover flushing the system the first time but my car is there again at the dealership for repeat repair. They flushed it this time and wanting me to test it out. They are having a hard time figuring out... Oh the the knocking from under the hood. According to the dealership.. that was a normal sound after they replaced 1700 worth of engine parts last year. I wont buy a GM car again.. Am going back to Honda...
