I replaced the radiator, water pump, thermostat, heater core, all hoses and I still have an over heating problem. The cooling fan? I am not sure it works. How do I test it? How do I replace it? Please help me with this problem. I'm tired of driving with the heater on, in 98 degree weather. Thank you

Check your oil and see if there is any water/ discoloration to it. Almost a rainbow color. This could indicate a blown head gasket or a warped head. How long does it take before it starts to overheat when driving it?

The oil is fine. I had an oil change a month ago. Usually it starts at about 50 miles. Then, on the heater goes.

Okay, have you tried to insure proper ignition timing. This could also cause overheating issues. To test the fan, just run two jumper cables from the battery to the connector on the fan. If it runs then its fine. However, when the car is overheating and the fan doesn't work then there are other issues. Let me know what you find out.
