    The Derale Fluid Control Thermostat is a billet-style cast aluminum unit with 1/2 inch NPT ports that manages oil flow to a remote cooler. It lets oil bypass the cooler until the fluid reaches 180 degrees F, then the internal thermostatic valve routes all of the oil through the cooler while holding system pressure steady. This helps the engine or transmission reach operating temperature sooner, which is useful in cold climates. The housing can be rotated 180 degrees to reverse the flow direction, and it carries an ultra-bright billet finish.
