My car after driving a long distance if i sit for more then 10 mins the car goes to 220 plus one time almost 240. The car used to be tpi now it is a carb. I checked all the sensors that plug into the ac and there all hooked up and the ecm is hooked up and it still runs my fuel pump and the fan that is controlled by a thermal switch. Before the carb swap it always ran cool it has a hypertech 176 fan switch and a mr.gasket 160 t-stat brand new water pump and radiator. Is that other fan not coming on causing my problem? (tryed to ground the adld and the fan doesnt come on same for when i turn on the a/c)

 

Ive got the Same Probelm, except I have single Fan.

Your Dual Fans Have seperate Relay's. So if one fan isnt Working, it should effect the other.
