Engine Cooling problem
1994 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic

The engine keeps over heating. The car has a new radiator, new water pump, new thermostat and a new radiator cap. What else can it be?

If you do not see any coolant leaking on ground, then cooling system could be blocked, cooling fan not working.

Worst case would be a bad headgasket.

Have a compression test performed, if OK, the drain and flush cooling system and make sure cooling fan is working.
