Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pump-Out Valves
The pump-out valves are used to balance the pressure in the passenger compartment.
The pump-out valves are equipped with rubber flaps. The flaps open when the air pressure is slightly higher in the passenger compartment than outside. When the air pressure is as high on the inside is outside the flaps are closed. This prevents water from entering.
On 4-door vehicles the air outlets are located in the edge between the rear shelf and the rear window. The air goes from here through the cargo compartment and out through the pump-out valves behind the rear bumper.
In 5-door vehicles, the air passes directly out through the air vents in the cargo compartment.
