How to Find the EGR Valve on a Nissan Frontierby Carl Pruit
The Exhaust Gas Recirculation (EGR) valve on a Nissan Frontier is a metal cylinder located at the back of the engine near the top. The EGR valve is responsible for taking the spent emissions and recycling them through the engine to be burnt a second time, limiting the exhaust fumes that are sent out of the tailpipe. Occasionally, the EGR valve will need to be replaced due to the emissions clogging up the valve and resulting in reduced gas mileage and a poor running engine. You can locate the EGR valve on your Nissan Frontier in just a few minutes to replace it.
Detach the negative battery cable of the Nissan Frontier from the battery post with an open-end wrench.
Unscrew the nut at the top of the air cleaner on top of the engine with a socket wrench.
Remove the air cleaner and filter from the top of the engine and set them aside.
Locate the EGR valve at the back of the engine in the center next to the firewall. The EGR valve sits on top of the intake manifold.
- Never attempt to replace the EGR valve of your Nissan Frontier while the engine is still hot.
