What could be the problem to my car overheating, I did a pressure test and the pressure held up. I heard that others have had problems with the intake manifold but I do not know if mine has that problem. What should I try or check?
Do you
have the same problem?

Did you check/test the thermostat-if not do it and also check the water pump if its pumping coolant thruout the egnine if okay-get a chemical tester and check for combustion leak

If the t-stat is working, flush the system and also, make sure there are no collapsed hoses.

What all hoses do I have to look for besides the ones going to, and coming from, the radiator?

Also I think I have a coolant leak and thats why it is overheating, but I have no idea where it could be coming from since the pressure test held up

There are two plastic elbows by the tension pulley that commonly leak on that motor you can buy them off the help isle at any parts store.

They are right by each other. When u buy them they should come together. And when they leak it burns off the monifold before it hits the ground.
