Engine Cooling problem
1994 Pontiac Firebird 6 cyl Automatic 150xxx miles

I bought my Firebird almost 2 years ago. Inbetween that time I have gotten the trans rebuilt and many other things replaced. Last summer I had gotten the water pump replaced due to a mechanic telling me that I had an anti freeze leak in my water pump and he put some stop leak in there that caused me to have other problems to go wrong with my car. The bad thing is I didnt know I had stop leak in my car until I went to have the car inspected due to the antifreeze leak. I get the water pump replaced, and then I had recently gotten a new radiator and on my reciept it says that I have a blown head gasket. My car doesnt smoke white or black, it doesnt smell, and as a matter of fact it actually runs like a beauty. But its still runnin hot after I gotten the water pump and radiator replaced. I have a new heater core as well. So now I am trying to figure out why is my car still over heater like this. I am hoping after the thermostat have been replaced that the car goes back to its normal self. But I cant see it being an head gasket because there is nothing out of the norm right now.

Stop leak does work, it not only stops leaks but also will clog up the system. If you have a 3.4 then you may have a intake manifold leak. That is what I am dealing with on my wifes car. What I would do is check the system with a coolant system pressure check to see if there are any leaks. And you can do a compression check to see if you do have a blown head gasket. You did not say if you replaced the thermastat. With stop leak sometimes it will make the thermastat stick. Even if it sticks a little it will cause the car to run hot with it not opening all the way. Try cleaning the system by back flushing the coolant system.

I was using the wrong anti-freeze. System should only use DEX-COOL. I mixed with pink stuff and it turns the liquid to a jel. After flushing system all is OK now.

I have been around a long time and had used prestone most of the times. Anti freeze just brings the boiling point higher and freezing temp lower. I don't think that just the anti freeze is the problem. If the engine runs that hot there is a problem. I don't run a car without a thermastat. Found antifreeze circulates through radiator too fast to cool down enough to keep it from overheating.
