How to Replace the EGR Valve on a Ford Crown Vicby Johnathan Cronk
The Crown "Vic," which is the common name for the Crown Victoria, is a full-sized vehicle designed and manufactured by the Ford Motor Company. As in most vehicles, the Crown Vic has an exhaust gas recirculation (EGR) valve, which controls the amount of gases within the combustion chamber. The valve uses a plunger mechanism to direct the exhaust into the intake manifold, where the exhaust is then properly cooled to prevent the vehicle from overheating. When the EGR valve clogs, it fails to operate properly and affects overall performance. Replacement of the valve requires minimal tools and keeps the Crown "Vic" running efficiently.
Place the Crown Vic in "Park." If the vehicle has recently run, allow it to cool for a half hour to ensure all components are cool to the touch.
Open the hood of the Crown Vic. Look for a mushroom-type valve behind the throttle body. Note that it has two small hoses attached at the top.
Remove the two hoses by pulling them gently from the valve by hand, one at a time. Do not use any tools to disconnect the hoses, as this could cause damage.
Loosen and remove the bolts securing the valve to the valve mount using a 22 mm wrench. Once the bolts have been removed, lift the valve from the mount. Removal may require some force if carbon buildup is present. Discard the old valve.
Clean the valve mount by spraying carburetor cleaner onto the mount. Clear away any debris or carbon residue using a wire brush and clean rag.
Install the replacement valve by placing it onto the valve mount. Align the holes on the valve with the holes on the mount to ensure the bolts fit properly. Tighten the four bolts using the socket wrench. Reconnect the hoses to the top of the valve by pushing them into place. Close the hood of the Crown Vic. Repeat these steps when a new valve is needed.
