The Silverado is a full-size pickup truck designed and manufactured by General Motors and sold under the Chevrolet brand. Silverado comes equipped with different size engines, including the V5300 5.3L V8 engine. The vehicle is equipped with a positive crankcase ventilation (PCV) valve. The valve has primary responsibility for removing exhaust gases to reduce pressure build-up in the engine crankcase. Replace the PCV valve at the first sign of failure to ensure the vehicle passes an emissions test and operates efficiently.

Step 1

Park the Silverado on a level surface. Let the truck cool down for half an hour before beginning any maintenance under the hood.

Step 2

Open the hood of the Silverado and locate the PCV valve in the rear corner of the driver’s side on top of the valve cover. The valve cover is placed behind the spark plug distributors. The valve is connected to a thick hose and is seated in a rubber washer.

Step 3

Remove the hose from the valve by pulling gently. A hose clamp can secure the hose in place; if so, use a flat head screwdriver and loosen the clamp.

Step 4

Remove the PCV valve from the rubber washer. Use a pair of needle nose pliers to grasp the valve and pull it out. Be careful not to damage the rubber washer. Discard the old valve.

Insert the replacement valve into the rubber washer. Push the valve down with your fingers until you hear it snap into place. Connect the hose to the valve by pushing it into place. If there was a hose clamp, tighten the hose clamp with a flat head screwdriver.
