How do I identify a Horton fan clutch?
Fan clutch part numbers are usually located in one of two places on the fan mounting surface. For on/off and two-speed drives, the part number may be on the front or back of the fan mounting disc. Other fan clutch manufacturers tend to put a printed sticker with the part number in a similar location on the drive.
Do I need a heavy duty fan clutch?

How does a fan clutch work on a Chevy?

What are the different types of fan clutches?
Types of Fan Clutches. The main types are non-thermal, thermal, and electronic — all of which use a silicone fluid to engage and disengage your fan. Non-thermal clutches operate solely based on the shaft speed of the water pump.
What’s the best temperature to test a fan clutch?
Make sure your new fan clutch is the same type as the original. It’s possible to upgrade from a non-thermal clutch to a more efficient thermal model, but not the other way around. Keep your engine temperature below 210 °F (99 °C) while you’re running your tests to prevent it from overheating. Thanks!
