InstallationInstructions
WARNING: DO NOT CAP OFF THE OIL COOLER PORTS after the
adapter is installed. Running the engine with the ports capped will
block oil ow and result in catastrophic engine damage. If not using
an oil cooler, the IN/OUT ports must be looped together to prevent
engine damage.
WARNING:This product should only be installed by a qualied me-
chanic. Improper installation could result in severe engine damage.
PreparingforInstallation
1. Raise the front of the vehicle and support with approved automotive
frame stands, lift, or ramps.
WARNING:NEVER work under a vehicle supported only by a jack.
2. Remove any underbody panels necessary to access the oil pan and
lter.
3. Remove the oil lter.
Caution: Oil may be hot!
a. Be sure to place a drain pan under the lter. Roughly 1 quart of
uid will drain out after removing the oil lter.
4. Remove the two bypass cover ange screws with a 10 mm socket or
wrench. Be sure to remove the factory gasket shown in Figure 1.
5. Measure and assemble oil cooler system lines. Leave the lines discon-
nected from the adapter and oil cooler.
