    Intercooler pump

    I just got the heat exchanger mounted on my car and ran it for a while but the intercooler pump never came on. Does that only come on at a certain intake air temp or is my pump bad? I want to get my heat exchanger filled up and purged.

    The factory setting are:

    Minimum Run time to enable pump is 10 Sec
    Minimum IAT temp is -13*F - Below this temp the Intercooler will be disabled
    Minimum IAT2 temp is 32*F - Below this temp the pump will be disabled.

    The IAT2 is the air temp after the blower in the manifold. So once you start the engine it should run pretty quick. I would check you power to the pump to see if is has juice.

    I jumpered it to get it purged so I know the pump works. I'll check it with the car running tomorrow but I'm pretty sure it's fine. I was paying more attention to the engine coolant level the first time. The car is done except for the inner fenders in front and the hood. It's getting painted on Monday. I need to adjust one headlight bracket too. Can't wait to start modding.
