How to Replace a Kia PCV Valve

by Johnathan Cronk

Kia Motors offers a range of vehicles including full-sized, mid-sized, compact sedans and SUVs. The positive crankcase ventilation valve, also called the PCV valve, within Kias removes gasses from within the engine. This prevents the vehicle from excess pressure buildup. When excess gasses buildup within the engine, the pressure can cause damage to the motor and surrounding components. It's important to replace the PCV valve at first sign of failure.

Step 1

Place the Kia in "Park" and allow the vehicle to cool for a half hour. This will prevent the valve and surrounding components from being too hot.

Step 2

Open the hood of the Kia and identify the PCV location. On Kia vehicles, the PCV is found below the plastic cover mounted on the top of the engine. The valve is a seated in a rubber grommet with a small hose coming out of it.

Step 3

Remove the plastic casing. Loosen and remove the four screws securing the casing in place. You will now see the PCV valve on the rear left side of the engine.

Step 4

Pull the valve out of the rubber grommet using a pair of needle nose pliers. The valve will slide out easily, be careful not to damage the rubber grommet. Disconnect the hose from the valve by pulling it straight out.

Place the new PCV valve into the rubber grommet. Secure the valve by pushing it straight down. You will hear the valve click into place. Plug the hose into the replacement valve. Replace the plastic casing and tighten the four screws. Close the hood of the Kia.
