Standard oil-to-water cooling uses the cooling system's thermostat to regulate both oil and water temperatures, but when oil-to-air Track Cooling is fitted, that thermostat is no longer available to the oil. Therefore an oil thermostat replaces the oil-water heat exchanger; it uses the same expanding wax pellet principle as the familiar engine coolant thermostat. This is a prototype of the oil thermostat--it's a billet piece for testing, but will be an aluminum casting in production. The thermostat is mandatory because water dilution (a normal byproduct of combustion) of the oil accumulates at low oil temperatures, plus the oil needs to be 180 degrees or higher for all its chemical additives to work properly.
