The PCV valve on a 99 GMC Yukon is found in the left valve cover. It allows trapped gases inside the engine to be recirculated and reused.
right side of engine on top of the valve cover towards the back.
The PCV valve on a 1999 GMC Jimmy is located on top of the engine, on the left side. It connects the valve cover to the intake manifold.
Where id the AC expancion valve located in a 202 gmc yukon with rear air
most likely on the left valve cover
On the engine valve cover on driver side.
PCV valve on top of the valve cover towards the end of the cover. Will have a 90 degree black rubber boot on it.
I anwered this question Look at post ... "Where is Expansion valve located on 2003 Yukon Denali XL"
remove the old pcv valve by pulling it straight out of the valve cover, pull the hose off the other end. Installation is the reverse of removal.
Inside the gas tank.
driver side, engine compartement
The PCV valve is just to the left of the carberator...if your looking at the carb. follow the hose comming out of the center of it (should be rubber and hard plastic combo) that plugs into the PCV valve. I believe the answer is that it does not have one...I have a 2000, and it doesn't have one......
