Repair Instructions




+If I'm converting from an HDMS/Cool Logic fan clutch into a Kit Masters conversion kit, do I need to change my fan blade too?

You do not need to get a new fan blade when you convert from an HDMS/Cool Logic fan clutch assembly. We designed our conversion kit fan clutches to have the fan blade mounted in the same position as the OE fan clutch/fan blade assembly.

+Do I need to reset my ECM when replacing an HDMS/Cool Logic fan clutch?

Yes, the ECM needs to be reset when you convert from an HDMS/Cool Logic fan clutch assembly into our conversion kits (ex: 24-462CK)
