Hello,

I flushed engine cooling system, installed new radiator, installed new thermostat, and installed upper/lower hoses.

Could someone tell me what else I can be missing beside the water pump?

Also when the engine temperature gage got to the 1/4 mark both fans came on so I believe we can rule out the fans and sensors.

The car seemed like it was staying cool when I let it idle but I turned the a/c on and it shot right up the 3/4 mark and I could not get it to come back down even at idle with the heat on full blast.

Thanks in advance! Any ideas?
Steven.

 

Does the car physically overheat, or does the gauge just shoot up?
