I still want to flush it 1 more time though to make sure its clean and run some radiator sealant through it to make sure there are no problems on that end. I haven't had the same problem recently and it's been running very cool and great, I'm still keeping a close eye on it though. I also hand to replace the coolant hose b/c it cracked and leaked coolant everywhere (it looked to be corroded on the inside of the hose). I recently flushed my radiator myself and got rid of the Dexcool and all traces of it that was there and replaced it with green coolant.
It was strange though b/c it would over heat at idle in park, but when it was in park and I pressed the gas, it would cool down which led me to several different conclusions. It was all good for a couple of months, then it came back. So' I added more coolant again assuming since it was so low last time it just went through the coolant i just added. It solved the problem for a while, but eventually it came back. I checked my coolant level and it was extremely low so I added new coolant. The first time it happened I was with my fiancee' in West Virginia to visit her family I was so embarrassed. After about 8 months I began to notice that it was overheating alot and temporarily losing horsepower. I bought my car in July 2008 from a dealership in Charlotte, NC. Word of advice: Avoid all 3.1L V-6 engine possessing cars! Example: Bonneville, Monte Carlo, Lumina, etc. Remember though, this engine wasn't just used in the Grand Prix models, it was used in other GM cars as well. They have since come up with a steal "fix" gasket that you can purchase at your local automotive parts stores. One thing I did find out was that there have been numerous people locally that have dealt with this same problem on the early model 3.1 v-6 due to the manufacturer using a hard plastic gasket. It would have been considerably more had I not done the work myself the second time around. So now it's safe to assume my lower intake gasket blew out again, but this time internally. When I checked the oil dip stick I found all my coolant had flushed into oil. It spit/sputtered as she pulled up to the house and thankfully she killed the engine before the engine seized up. As the problems seem to ease up and thinking that I've got the problems under control, about 18,000 miles later, the car starts to overheat on my wife. So I spent about $500 in parts to replace the gaskets, coolant, radiator cap, temp sensor and thermostat. But it gets worse, as I get the car paid off and I have about 80,000 miles on it, the lower intake manifold gasket starts to leak. Ok, so I have this Pontiac Grand Prix 3.1 V-6 that seemed to be a really great car for the first year, but then all the windows started to break down multiple times, the key got stuck in the ignition 2 different times over the course of a 4 year span.
