Plenum Water Flow Direction and Cleaning
A large percentage of water will flow off the windshield area into the plenum
chamber drain system and then
down the outside on the plenum to the underside of the vehicle. To ensure that
the plenum chamber water
management system performs properly, the air inlet grille panel, plenum chamber,
and drains must not be
blocked with debris.
In the graphic below the gray arrows show the water flow direction in the plenum
chamber and drains system.
