The Mocal thermostat is the first, and only, oil take off for the GM LS series engines to incorporate a thermostatic control that automatically regulates oil flow to connected cooling devices, and is the answer when installing oil cooling on high performance engines that see street/track use in varying climates and conditions.
The unit simply bolts in place of factory gauge sender and operates by bypassing oil until minimum temperature (200f) are met before sending full oil flow to the cooler(s).
