In this video we walk through the OEM steps to replace the purge valve and vent solenoid on a 2018-2024 Buick Enclave and Chevy Traverse. We also briefly talk about some of the common EVAP codes you will find on GM's 3.6 engine and why I would start with the purge valve if you have general EVAP leak codes. This process is the same for various other GM vehicles with the GM 3.6 engine including: Buick Enclave and Lacrosse, Chevy Traverse and Blazer, Cadillac XT5 and XT6, and GMC Acadia and Terrain.
If you haven't replaced your purge valve yet on a Gen2 Buick Enclave or Chevy Traverse, you may want to bookmark this video as you will get these codes around 75k miles. Unfortunately, it's not a matter of if, it comes down to when you will need to replace!
