Q: Where Is the EGR Valve Located In Your Car?

A: The exhaust gas recirculation (EGR) valve is a vital part of the emission control system. It returns some of the exhaust gas to the combustion chamber. The gas lowers the temperature required to burn the air-fuel mixture, which reduces the amount of toxic nitrogen oxides produced by the process.

In most vehicles, the EGR valve sits on a pipe that connects the exhaust manifold or intake manifold.

In most vehicles, the EGR valve sits on a pipe that connects the exhaust manifold or intake manifold. Vehicles fitted with a carburetor might have the valve located on top of the engine’s rear near the firewall.

The EGR valve’s location can vary according to the vehicle’s model and model year. In the 2001 Ford Excursion, the valve sits on the intake manifold’s top behind the throttle body. Meanwhile, the 2005 Dodge Ram 1500 EGR valve can be found on the right front cylinder head beside the alternator. And the EGR valve of the 2005 Chrysler Town & Country is located above the alternator on the sideways-mounted engine’s left side.

Tips On How to Access the EGR Valve

The EGR valve is easy to access, so you can easily remove it for cleaning or replacement. However, there are vehicle models where the air cleaner duct or engine cover partially blocks the way to the valve. Use a Philips or standard screwdriver to unfasten the obstructing parts and move them out of the way.

You also have to disconnect the car battery’s negative terminal before doing anything. Some vehicles require you to enter a security code after you reconnect the battery, or else they’ll keep the electronics turned off. You can usually find the code in your owner’s manual.
