The engine intake system within your Ford Focus relies heavily on the exhaust gas recirculation valve, commonly called the EGR valve. The valve is crucial to your intake system, as it directs exhaust into the intake manifold, which is where the exhaust is cooled, preventing your vehicle from overheating. The valve can become clogged over time, making it defective. If that happens, the EGR valve should be replaced immediately. Replacing the EGR valve in a 2002 Ford Focus takes just a few steps, and a replacement valve can be purchased at any local auto parts store.
Allow the Ford Focus engine to cool down. This will give the components within the vehicle ample time to cool, preventing burns.
Open the bonnet of the Focus. Notice the EGR valve, which is a circular valve located on the engine intake manifold. It is secured in place by bolts. Refer to the Ford Focus manual for a diagram, if needed.
Use a socket wrench and remove the bolts holding the EGR valve in place. Lift the valve off the manifold. Use carburettor cleaner and clean the valve mount where the old EGR valve sat. Wipe the area clean with a rag.
Install the new valve by placing it onto the valve mount on the engine intake manifold. Place each bolt in place and tighten using the wrench. Close the bonnet of the Focus.
