Guys...i took my coupe to a mechanic that does some of my work so he can install the e-fan and he called back saying that it would not clear the water pump??? Is this true? If so, how is everyone else running these e-fans on their cars? I dont even have a thick radiator in there...i'm not worried about connecting the electrical part of it but installing the e-fan in place on the radiator...all help appreciated!!!
