If it was my car I'd replace that 4 blade fan with a new aluminum fan and rebuild the water pump. Rebuilding the pump is easy. When you replace the rear bushing make sure the casting isn't cracked where the bushing fits. I don't worry about a very short crack at the rearmost edge, but some cracks run up to the flange area and then the housing should be replaced. I'd buy the brass bushing with the seal in the rear. Some vendors have a bushing with a double lip, and others have a single lip. I prefer the double lip, but either one should work fine. Be sure to use new lead packing rings (2) in the new packing nut, and put lots of grease around the lead rings as you install them in the nut. My pump done this way has not leaked a drop in over 10 years.
