 pvc location
Hey. For a while i could not find the pvc valve either. Facing the engine, it is on the driver side if the engine almost to the back. it is a free floating piece not conected th the engine itself, unlike most vechicels. as a graph- look center to the compressor, now go back untill you reach the last sparkplug. it is located there. if you buy the pvc at a auto parts store (i think it is 147 pvc) you have to remove the black top with the 2 plastic tubes. the metal part is what the pvc valve looks like in your truck. |
