How to Clean an EGR Valve in a Subaru
- 1). Allow the Subaru to cool for at least a half hour before attempting any work under the hood to prevent potential burns.
- 2). Open the hood of the Subaru and locate the EGR valve on top of the engine intake manifold.
- 3). Use a socket wrench to loosen and remove the bolts that hold the EGR valve in place. Pull the EGR valve off the manifold; it may require some force if there is a lot of buildup around the valve.
- 4). Spray carburetor cleaner on the EGR valve cover and inside the valve. Clean away loosened dirt with a wire brush and clean rag until you notice the valve moves up and down smoothly. Continue this process until the buildup is gone.
- 5). Clean the valve mount on the manifold where the EGR valve sits. Spray carburetor cleaner into the two holes under the valve mount and clean with a rag.
- 6). Place the EGR valve back onto the valve mount on top of the engine manifold. Replace each bolt, and tighten them with the socket wrench.
