I used one from a junked 2.5 ltr. cavaleer. I first ran it direct wired then I added a remote mount thermostat.The part # I obtaned from a flexalite fan instalation scamatic I down loaded from one of the 4x4 parts places on line catalogs. I mounted the fan using the cavaleer shroud. Most of the stock mounting locations on the radiator were used and that galvanized mettal tape used to replace muffler mounts was used span the gaps betwean the stock mounting holes and the ones in the Cavaleer shroud. It took me 2.5 hours. I am not a eletrician or traned mechanic so I went slow and checked and rechecked every thing. It did not take long to figure out the proper ajustment for the temp and I have about 5000 miles with this set up with zero problems, an increas in M.P.G., faster warm up and a little extra HP at the wheels. If you can get a Tarus fan or one with as flat a motor use it. The cavaleer motor is 4in deep and requires it be off set to one side of the water pump pully.
