A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.

It sounds like you may need to replace your thermostat. Even though you have enough coolant in the radiator and overflow reservoir the coolant may not be circulating through the system because the thermostat is not opening. When the coolant can't flow through the engine and radiator it will get very hot and stay very hot. This is usually an inexpensive and fairly easy fix, just purchase a new thermostat and install it or have a mechanic do it for you.

Why does your 94 Oldsmobile cutlass supreme over heat?

There are 2 reasons that I've heard of that may cause a car to overheat: 1. You need a new thermostat--the engine coolant is not getting into the engine 2. You need to replace the head gasket on the engine--this can be thousands of dollars, so maybe have the thermostat checked out first. If the radiator only comes on when the A/C is turned on, the Radiator coolant switch may need changing
