2017 Sierra Adaptive Valve Delete


Recommended Posts

I can Confirm that the chirping-squeeking noise on start -up is definitey caused by the Adaptive flapper valve. had my truck on hoist today could physically see it rotating and chirping on acceleration and start up. Just turn it counter clock wise and clamp it open. No more squeal or chirp on start-up.
