This thermostat is perfect for engine oil cooling in motorcycles, ATVs, go karts, and other small engines.\u003c\/p\u003e\n\u003cp\u003eThe patented internal design (US patent 9,772,632) minimizes the pressure drop by strategically locating the bypass valve mechanism completely out of the primary fluid flow.

Oil thermostats perform the critical function of bypassing the cooler until the oil has reached its minimum operating temperature. A more capable cooler will often require an oil thermostat in order to maintain proper operating temperatures under low load conditions, cold weather, etc.\u003cbr\u003e\u003cbr\u003eThe thermostat maintains the oil exiting the engine at the rated minimum temperature in most conditions. It features female -6AN O-ring boss threads and is available with optional hose barb and male AN adapter fittings.
