As the fluid temperatures exceed 180° F, the thermostatic valve closes, allowing 95% flow through the oil cooler. At temperatures below 180° F, the valve is open, with 90% of the oil bypassing the cooler. The remaining 10% of the oil flows through the cooler, maintaining constant system pressure, preventing air pockets and eliminating cold oil shock. Shown with included Brass Fittings. Uses a 3/8" Pipe - 1/2" Hose.
