I googled "'62 Impala engine bay" for images to see what the set up was like. As with all chevy cars from the early 60's - mid to late 70's, you have to pull the passenger side inner fender well. Once you get it out, the fan motor is right there. Make sure you use some sort of lube on the bolt threads to aid in the removal.
