    Earl's Temp-A-Cure Oil Thermostats are manufactured from unplated 6061 Billet Aluminum and are designed to insure quick warm up under cold weather conditions. These oil stats work the same way a thermostat controls the water temperature in a radiator, they begin opening once the oil reaches 160°F and fully open at 180° F. The remote style features three 1/8'' NPT ports for monitoring oil pressure, tempurature and flow. The sandwich style mounts between the engine block and oil filter eliminating extra plumbing. Both styles feature -10AN female o-ring port fittings for use with popular AN port adapter fittings to make easy work of plumbing to your Earl's Temp-A-Cure Oil Cooler!

    501 is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Good product but be sure to order EARLS fitting I purchased this thermostat thinking that my current 10AN fittings would work. But NO! I ended up ordering EARLS AT985010ERL 10AN fitting. This has put the project a week behind. The parts should be delivered today.
