Overly cooled oil robs an engine of power and can lead to increased wear and sludge formation. An oil thermostat allows the oil to bypass the cooler until proper temperature is reached. This model has fairly large internal passages and is available with either 3/8 NPT or 1/2 NPT female ports. The female ports make it easy to adapt to just about any installation. The thermostat opens at 180°F/82°C +/-10°F or +/-3°C.
We also offer Oil Thermostats with Male AN Fittings (Part No. 1226-Size), which have larger internal passages and greater flow capacity. They are more expensive, but they do not require adapters in most installations.
