I changed the thermostat and had the radiator flushed. What else is there?

It's a '91 corolla. I replaced the radiator in 2000 and skipped a major tune-up for ~2 yrs. Do you think I need to replace the radiator?

There are no leaks and the radiator is flushed so coolant is filled. My uncle thinks the radiator needs to be replaced because the car's engine is so old that debris is being carried into the radiator. What do you think?

Maybe it could be the water pumb, if I remember correctly.

My suggestion is to have the Radiator Cap checked. A defective radiator cap can cause a problem. I have also seen defective water pumps cause this problem. I have seen water pumps, where the impeller came apart slowly and caused a loss of flow. Here is what I suggest, when you start the vehicle. The lower radiator hose should be stiff and get warm and until the Thermostat opens and allows flow, the upper hose should be easy to squeeze and collapse with your hand. Once the thermostat opens, the coolant should start flowing through the radiator....to check that...once the engine reaches operating temp, both hoses should be stiff and hard to collapse. If the upper hose is easy to collapse once the engine is warm, then that would indicate a flow problem, like a thermostat not opening up once it reaches a certain range. You need to make sure that you have good flow through the radiator for it to not heat up.

If its an older vehicle, the radiator cap could be bad and cause the water to heat up more due to not being under more atmospheric pressure. Also, i had a Caravan that the thermostat had to be in just so or it still would overflow.

Overheating is a radiator/coolant problem alone. You might want to replace it...
How long have you had the car? Did you keep it well-maintained?

Those small cars use electric light weight fans and when you are driving down the road the air cools it, however when it's idling or heavy traffic the fan is not turning, have you checked it?

it can be the radiator or the water pump that it broke. if you car is leaking than the problem is the water pump.

Maybe it's the fan belt.
