HELP! I just got a 2001 Chevy Malibu, and it overheated the same day I bought it, but they won't give me back my money. I didn't pay a lot for it, and otherwise it is a solid car, and everything else works, and I don't mind putting a few hundred into it, but don't have enough to replace an engine that would cost more than what I paid for it. I took it to a mechanic today that I trust, that said it has large amounts of Stop Leak in the coolant system reservoir, that has boiled out of the overflow, and that needs to be replaced before they can tell what is actually going on with it. So I told him to go ahead and replace it, and left it there so they can finish doing the diagnostic tests on it, and now am just waiting for the bad news. They said it could either be blown head gaskets, a cracked engine, the water pump, the radiator, condenser, or a combination of things. There is nothing at all leaking underneath, and it takes about ten minutes from a cold start before it goes to the red and dings. It isn't backfiring, and there is no smoke coming from the hood when it gets hot, or smoke coming from the tailpipe. The heater doesn't work, but the ac does. When I bought the car they didn't have any gas in it, and I only drove it around the block, and because I am disabled, and going through some serious medical issues, I rushed into buying it, and wasn't thinking straight. I found out it has only had 2 owners, and the first owner had it almost the entire time, and took very good care of it, and had regular oil changes etc. And the body has no rust, and everything else works great. Then the last owner had it just a few months, and then sold it, so I am guessing he is the one that put the Stop Leak in it. Does anyone have any ideas what may be wrong with it? I am praying it isn't the engine, and just the radiator, or water pump, just something that is a few hundred to fix, and just wished I knew why the last guy sold it, so I would know for sure what is wrong with it that needs fixed. The dealership still hasn't sent me any paperwork, so I have no idea who the last owner is to even try to look him up to find out. I am so depressed because I need a vehicle now with my medical problems, and don't have the time, or money to waste.
