you could have a bad hose, check the upper and lower hoses and hake sure they are not caving in on themselves. sounds like it could either be that or you might have something cloging the hoses. run the engine with the hood open so you have the pressure build up, and look at both raditior hoses. see if they are bulging out as pressuer gets built, or if they cave in .

If your loosing coolant then this is the reason for over heating.If it is leaking around the intake gasket then it could possibly be the intake gasket itself.What you should do is have the cooling system pressure tested.The throttle body gaskets were good for leaking coolant on these 3.8 engines.There was a recall on them at one time.Not sure if it would still be covered.You can call the dealership and give them your vehicle identification number and they will tell you if there are any open recalls on your vehicle.This would be a free repair on the throttle body only.Hope this helps.Good luck.

sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!

Testimonial: "thanks very much. i'll check that out."
First thing that comes to mind would be a bad thermostat, either stuck or installed backwards. I've seen lots of bad "new" ones, try another before going too deep into this. Also, when does it overheat? Driving, loaded, at idle?
Make sure the system is bled, sometimes this is difficult and takes a couple heat cycles.
When you say reman. "heads", I'll assume that you have the V6 engine. These engines had problems with corrosion around coolant passages in the block. It's possible that even after doing the head gaskets, that combustion gases are escaping into the cooling system causing the engine to overheat. If you have the equipment, it would be helpful to plumb low pressure air into each cylinder at TDC to check if air is making it's way into the cooling system by watching for air bubbling at the rad filler.
Hope this helps,

It is best to be systematic about this. It could be either the water loss or the overheating which is the basic cause, either one could come first.
- there is a test for combustion gases in the water jacket, from a blown head gasket. This will very quickly cause overheating, and the excess pressure will blow the water out the overflow reservoir. If the car has already overheated and died, this is unfortunately quite likely
- the temperature sensor in the block may have failed. This will prevent the fans from running when the engine overheats, and you can see this. The fans are not driven by a belt. P68....
- the thermostat may have stuck closed. You will have to get it out and test it, but this is not difficult. See p328
- this model of Camry has a plastic top tank to the radiator, which eventually cracks. Look there carefully.
- it may be that a radiator hose has gone soft and closed up. Check they are allowing good coolant flow.
- it could be that in a car this age that the radiator has silted up and is not allowing coolant through. Disconnect the top and bottom radiator hoses, when cool, and run water through from a garden hose to get some idea about that.
