I have a 1996 Pontiac Grand AM and it keeps showing signs of overheating. Whenever I have the heat on for a certain amount of time the thermostat goes up, almost to the peak temperature but when I turn on the cool air it goes back to the half way zone. Also when I accelerate in the beginning of driving my car I would hear this bubbling sound. What's up with that. Please help. Why do I always have car trouble when I get a lot of money.

Make sure your radiator is full of coolant first...when engine is COLD, open the radiator cap. if it's full, then you may have a thermostat partly sticking.
Also, make sure the electric cooling fan does come on (it's on the radiator), and the temp gage should come down some. Don't run a/c while testing that, you want to see if the "thermo switch" actually turns on the fan here!
If all those are ok, then you might have a water pump going bad...
Hope that isolates it...

Like charlie suggested, the right end needs to be torn down. because that is overheating and also you keep having to characteristic coolant, i imagine coil p.c.. is wishful wondering or at maximum ideal a pink herring. replace the intake manifold gaskets, head gaskets and each and everything above that, have heads inspected and machined if nonetheless solid. determine out what's incorrect with the cooling equipment so this does no longer take position again. Water pump, radiator, thermostat etc. The fan will be the in trouble-free terms root reason, yet make certain.

There is a thermostat right under the long return hose mount right on the engine itself. There are 2 hex bolts, 13 mm on there. Remove those, right below those is the thermostat, Replace it.
Get Thermostat At Autzone, Peps or AutoParts for less than $10. Drain your fluid first of course, there is a petcock on lower right side of bottom of radiator.
If that doesnt work, your radiator is plugged. No amount of nonsense backflusing or cleaning will unclog it. Replace it and save that money putting it into a new radiator. Cost about $250.

I had the exact same problem with my old 1986 Grand AM. It was overheating to the extreme when coolant was added. The only thing that made it cool down was water- no coolant. I ended up replacing my thermistat and coolant system...and the problem still continued. Eventually it blew a head gasket and flooded the entire engine-fuel system-plugs- everything with oil.
My suggestion- get a new car.
