Proprietary OE Fixed Design

GMB has supplied and worked with OEMs for years and knows most fan clutch issues relate to noise or oil leakage. To prevent oil leakage, GMB Fan Clutches include an oil seal on top of the rotor. GMB also revised the design of the oil seal from a single oil seal to a double oil seal and expanded the return hole to retrieve all oil from the rotor.

Educate Your Customers About Preventative Maintenance!

Preventative maintenance is the key to maximizing the performance and durability of any fan clutch. Here’s a list of maintenance tips to share with your customers:

  1. Ensure the thread surfaces of the Fan Clutch and Water Pump are clear of any debris.
  2. Screw the Fan Clutch onto the Water Pump threads ensuring the threads interlock properly.
  3. Torque the Fan Clutch to the correct specification, following the manufacturer’s recommendation.
  4. Use tools specifically designed for the Fan Clutch to ensure the pulley does not move while turning the threaded nuts.
