Up for bid is this NORS fan clutch Four Seasons part # 36973. This piece fits 1996 and GM, Chevy, Buick, Pontiac and Olds Trucks, Vans, and SUVs. These are necessary to keep your vehicle temps low and steady. Don't let your engine overheat with a poorly working fan clutch. Installation instructions are included.
