Removing the EGR valve from your Ford Mondeo will take just a few minutes. The exhaust gas recirculation valve, which sends unburned emissions back through the engine in order to reduce the amount of exhaust from your Mondeo, is underneath the plenum in the back of the engine. You can remove the EGR valve yourself with common tools, saving you time and money.
Locate the EGR valve on the back of your Mondeo's engine near the firewall and just below the plenum. The EGR valve is a silver-coloured cylinder with a rubber vacuum hose attached to the top.
Unplug the rubber vacuum hose from the top of the EGR valve by hand.
Loosen the nut underneath the EGR valve with an open-end wrench. Slide the metal exhaust pipe out of the way.
Unfasten the bolts holding the EGR valve to the engine with a socket wrench. Remove the valve from the Ford Mondeo engine compartment.
To avoid burn injuries, always let the Ford Mondeo engine cool down before attempting to remove the EGR valve.
