Having problems with your 2000 Pontiac Sunfire ?
This car keeps over heating. I have changed the thermostat, the fuse for the motor fan and the radiator cap. The car has blown three 30 amp fuses for the fan. The fluid is not coming out of the reservoir however the engine head is super hot. The car over heats within a mile of driving and the gage shoots up to 125 and bounces The car over heats after idoling for 20 minutes. What is causing the fuse to blow?
