    What is this Part?

    Can someone tell me what this part is?

    It sits right under the coolent container. I think it may be some type of water pump. Mine is dripping coolent.

    Hard to change?

    It is the HVAC coolant pump. It improves coolant circulation through the heater core.

    Easy to replace.

    If it right by the res I have a feeling you're talking about the black box with lines on top of it? If so that's the air intake, that shouldn't be dripping anything.

    A picture would be good though!
