It uses compressed air to engage and disengage the engine cooling fan, helping regulate engine temperature and reduce parasitic drag when cooling isn't needed. The Kit Masters 8901N features a dual seal design for improved reliability and an Auto Lock fail‑safe that engages the fan if air pressure is lost, preventing overheating. When the fan clutch fails, you may experience overheating, excessive fan noise, or a fan that won't turn off; replacement is typically needed when seals leak, bearings wear out, or friction material deteriorates.
