Water Management Description and Operation
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.
Plenum Chamber and Drain Valve-Cleaning
