WARNINGS & PRECAUTIONARY STATEMENTS
WARNING: NEVER work under a vehicle supported only by a jack.
WARNING: DO NOT CAP OFF THE OIL COOLER PORTS after the

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.
