Just put on a semi emergency fan clutch 7 in. thermal........My old one was worn out from bad motor mounts. Barely spun and engine was runnihg hot. This new one is great. Giant wind goes thru the whole garage , and the sound is large. Wonder how many complain about overheat , and this is the culprit. Got this for twenty three bucks with Advanced points and five dollar coupon. Same one is forty three at LMR..Hayden unit...Happy again eleven mm wrench See those little tabs I made them with a big washer that I cut with a grinder...Works good for broken shroud where it screws in.
