i am having cooling issues at low speeds/idle and am looking for a 5” water pump pulley. Where did you get a 51/4” pulley?
The shop manual for my 71 318 and a/c calls for a fan to crankshaft pulley ratio of 1.3:1. My current set up gives me a .92:1. I want to leave the crankshaft pulley alone so as not to speed up alternator.
Thanks a ton.
