How to Replace Purge Valve 2000-06 GMC Yukon

I'm gonna take this cover off using an 8-mm socket and slide it off. And the purge valve is located right here. Disconnect the connector. Just slide underneath the lock. Disconnect that. Disconnect the hose. You can use a little pocket screwdriver. Just push on this little lock right here and then that'll release the hose. Just slide it up and, using an 8-mm socket, take this bolt out. Pull that out. And grab the purge valve and just slide it right up. There's an O-ring right there. And take this rubber piece off the old one. Take the new one, just slide it right over like that, and slide it in position. Put the bolt back in and tighten it down. And just snug it up. That's good. Reconnect the hose. Lock it in place, make sure it's good, and connect the connector. There you go. Take the cover and line the cover up in the back. And get the bolt started. And tighten it up, snug.
