i have tried everything.1st it had a radiator leak so i fixed that hoping that would be the problem....Nope still overheating.i tried bleeding the cooling system (well tried!) when i open he cap and start the car it seems to create endless amount of bubbles so bleeding it is not working.I removed the thermostat about 6 months ago and it didn't overheat for the 6 months it wasn't in there.but now 6 months later its starts overheating again.And i know these 3.4l engine are know to be complete crap and they are.But i check the oil its not milking or anything either is the coolant so the head isn't bad (yet) it has a brand new radiator.i just can't think of anymore thing it could be.The water pump?.i will drive about 5 miles and it will start to get hot if i give it a lot of gas it cools back down..Now if i didn't know any better i would say that sounds like a thermostat but its not even in the car.Could this be a blockage?.Please help me out on this one guys.....Thanks in advance

Are you still getting bubbles when you bleed the system? That should not happen and sounds like a head issue (gasket or head itself). You can have exhaust getting in coolant and not oil. This depends where the leaking is occurring. I highly suggest a block test...

++++1 on the block test. The car should really have
a thermostat installed.

Are the cooling fans working?
