Wanting to get this electric fan shoehorned in here. I have my inter-cooler stuffed as far forward as I can then my AC rad. So there’s not much room for the radiator and electric fan. I need to grind off the threaded part that used to hold on the mechanical fan. It’ll give me about 3/4 of an inch clearance. I can always buy another one if I want to change it back right? Or will I have to change the whole water pump?
