Open the hood and locate the EGR valve. On most Ford models, you will see the valve mounted on one side of the engine, towards the front or back of the engine. Depending on your particular Ford model, the valve may resemble a flat, metal mushroom, of about 2 to 3 inches in diameter with a vacuum hose on top; or a small plastic component with a rounded hat on top and an electrical connector.
#
2

Unplug the vacuum hose or electrical connector from the top of the valve, depending on your particular model.
#
3

Unscrew and remove the two mounting valve-to-engine bolts using a wrench or ratchet and socket.
#
4

Disconnect the pipe from the bottom of the EGR valve using a wrench or adjustable wrench, being careful not to damage the connecting nut.
#
5

Lift the valve away from the engine compartment and remove the gasket.
#
6

Detach the EGR solenoid from the top of the valve, if your particular model comes equipped with one. Remove the four screws using a Phillips screwdriver.
