Last Thursday my radiator decided to call it quits, so while I was putting in the new radiator, I figured why not take off the stock fan like I saw on Dino's site. Im not too sure of much of a performance gain, but I can tell that the jeep sounds different when it's cold out and the fan doesn't slip after cold start. I was curious if anyone else tried this and how it went. Also, the pulley that held the stock fan somehow managed it's way into the radiator, worn motor mount possibly? Any ideas would help.
