What other cars does the Foxbody share its water pump pulley with? I've got underdrive pullies and am running hot and would like to go to the "pull a part" yard and grab a water pump pulley from another car.
Im not sure there the same but one car you might want to cheak out is one of those early 90's lincons with the 5.0 efi take an pic of you pump and bring it down there and see if they match.
go get a 93 Cobra pulley. This unit is an overdrive unit and runs the watr pump at a higher rate then stock. I did this on my 93 and it runs cool all the time.
