CAUTION: A new power transfer unit (PTU) must be installed any time the PTU has been submerged in water.

NOTE: The power transfer unit (PTU) is not to be drained unless a leak or contamination is suspected. To drain the PTU fluid, the PTU must be removed from the vehicle. The fluid that is drained may appear black and have a pungent odor. Do not mistake this for contaminated fluid. For additional information, refer to Power Transfer Unit (PTU).
