How to Replace the EGR Valve for a Dodge RAM

by Will Chandler

The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum-controlled valve which allows exhaust back into the intake manifold in controlled amounts. The EGR valve can clog and get contaminated over time by carbon buildup, at which point it will require replacement. A malfunctioning valve can cause the engine exhaust pressure to drop and send engine warnings to the computer. It can also cause engine back pressure to drop, reducing gas mileage and engine horsepower.

Step 1

Locate the EGR valve in the engine bay. The year and make of the Dodge vehicle determine where the valve is located. This is on the front of the engine block, next to the timing belt in model-year 2005 and newer trucks. In older vehicles you will typically find the valve behind the engine, near the firewall.

Step 2

Unclip the exhaust tube from the side of the valve. You can do this by hand. Shift the tube from side to side until it slides off.

Step 3

Use a flat-head screwdriver to remove the EGR valve from the exhaust tube. There is a screw on each side of the tube.

Step 4

Disconnect the harness from the EGR valve. Use your hand to pull up on the tab and slide the harness from the valve.

Step 5

Use a flat-head screwdriver to remove the two screws that secure the EGR valve to the cylinder head. Remove the EGR valve and clean the surface of the cylinder.

Step 6

Attach the new EGR valve to the cylinder head and tighten it down with the same screws that were previously installed.

Step 7

Reattach the harness and reattach the exhaust tube to the valve. Tighten the two flat-head screws that hold the tube to the valve.

Step 8

Reattach the hose to the valve and use your hand to attach the clip to the hose.
