How to Replace the EGR Valve on an Acura

by Carl Pruit

Replacing the EGR valve on the Acura engine is a job that can be completed in just a few minutes. Located at the back of the Acura engine just above the intake manifold, the Exhaust Gas Recirculation (EGR) valve is responsible for recycling the emissions gases back through the engine in order to burn off as much of the exhaust fumes as possible. You can replace the EGR valve yourself, saving you time and money.

Step 1

Unfasten the negative battery cable of the Acura from the battery post with an open end wrench before replacing the EGR valve. Locate the valve on the back of the engine at the top of the intake manifold.

Step 2

Take the rubber vacuum hose off the side of the EGR valve, sliding it off the metal port by hand. Remove the electrical wiring harness from the socket at the top of the valve, unplugging the wiring harness by hand.

Step 3

Loosen the bolts at the base of the EGR valve with a socket wrench and lift the valve off the intake manifold. Clean away any remaining gasket material with a putty knife from the top of the intake manifold where the valve was sitting.

Step 4

Attach the new EGR valve and gasket to the intake manifold with bolts. Connect the electrical wiring harness to the top of the valve, plugging it into the socket by hand.

Step 5

Slide the rubber vacuum hose onto the metal port on the side of the EGR valve by hand. Attach the negative battery cable to the Acura battery post with the open end wrench.
