There are many types of fan clutches. Make sure you get one for your engine. They are made to let the fan free wheel to save fuel and not over cool. Mostly they are made to cool not look Kool. Don't believe everything you read in the speed parts catalogs or the internet. Parts companies are there to make money. The internet is made to confuse people or maybe the other way around! Then again your local autoparts store has counter persons working there because they hate working in fast food places. Not because they know about car parts. Be careful when you order a clutch fan, fuel injector, or burger.
