In this video, I demonstrate how to quickly test your boost bypass actuator. This method doesn't require any special tools or technique. You are simply checking to see that both chambers of the actuator are sealed and not ruptured. These can be a little tricky to source nowadays due to there being many different versions with ports clocked in different directions so if you need a replacement, make sure you get the right one if you're going for an OEM replacement. That said, they all work about the same and I have interchanged them before on my truck with different models in a pinch. Vehicles that will have this bypass actuator or similar include but are not limited to: SVT Lightning, SVT Cobra, Supercharged 3800 cars such as Pontiac Grand Prix GTP, and Buick Regal GS, Nissan Xterra and Frontier, GT500, and LSA applications (among others). A symptom of this failure would be the car not making as much boost as normal and blower over temp.
