TOOLS NEEDED
Warning: Installation of accessories should only be undertaken by those with mechanical knowledge and are familiar with working on
vehicles. Always use eye protection (goggles, safety glasses or shield). Park the vehicle in a well lit area, on level ground and apply the
parking brake. Only work on a cold vehicle that has been sitting overnight, failure to do so will result in severe burns and injury. Before starting
the vehicle, make sure no tools or any other items are left under hood that could interfere with or be drawn into moving parts of the engine.
Failure to follow instructions can lead to severe damage and personal injury.

How It Works:
When the oil is cool the valve is in the open
position, allowing oil to be applied equally to
both the inlet and outlet of the cooler,
preventing oil flow through the cooler. As the
oil temperature approaches 180ºF the valve
begins to close, forcing all of the oil to flow
through the cooler and return through the
valve to the source. This fail-safe design
insures full oil flow to the source regardless
of whether the valve is open or closed. The
cooler remains full of oil at all times,
eliminating pressure variations, aeration and
foaming of the oil.
FLUID CONTROL THERMOSTAT INSTALLATION
ROUTING HOSES
1. Install the into the four ports using Teflon tape or sealer on the threads.
2. Choose where you want to interrupt both oil lines to install the Fluid Control Thermostat. Thermostat needs to be securely
fastened to the vehicle frame, fender well or other stationary location (Mounting Hardware Not Included).
3. Splice into the lines connecting the Engine / Transmission to the Oil Cooler. Following connect the lines from
the Engine / Transmission and the Oil Cooler in the orientation shown above. Be sure the Hot lines are connected to the hot
side of the Fluid Control Thermostat and that the oil flows in the direction of the arrows.
4. Securely fasten all hoses before starting the vehicle.
5. Start the engine and check for leaks.
When routing hoses, be sure to keep all hoses away from sharp edges, moving parts and hot engine components.
Hoses should be routed carefully and should not be bent in less than a 5” radius.
A kinked hose will restrict flow and could cause failure.
