This oil cooler thermistor switch sensor restores proper cooling fan operation on select Polaris Magnum, Trail Boss, ATP, and Xpedition models equipped with an oil cooler fan system. The sensor installs directly into the oil cooler and monitors oil temperature to trigger the cooling fan when required, helping maintain proper operating temperatures and prevent overheating. Designed as a direct-fit replacement, this sensor installs in the factory location with no modifications required and replaces the original failed or inaccurate thermistor commonly responsible for inoperative oil cooler fans on compatible models.
