1993 Ford Econoline Remove EGR Valve
The exhaust gas recirculation (EGR) valve on a 1993 Ford Econoline van takes exhaust gases from the exhaust manifold and puts them back into the engine's combustion chambers, which helps to reduce vehicle emissions. When the EGR valve goes out, the emissions are affected, too. Depending on your state's laws, this may mean that your van won't pass an emissions test. To fix the problem, you'll have to remove the EGR valve to replace it.
Remove EGR Valve
- Allow the engine to cool to minimize the risk of burning yourself. Open the hood and locate the EGR valve on the engine, which is connected to the passenger side exhaust manifold by a tube that goes to the cylinder head of the engine. There are two exhaust manifolds on the engine, one on the driver's side and one on the passenger side. They are located in the vertical center of the engine, on the sides by the fenders. The manifolds are cast iron and are next to the spark plug wires. The EGR tube is toward the front by the fan belt.
- Remove the vacuum line running to the EGR valve using either the pliers or the flathead screwdriver, depending on the type of clamp holding the line in place. One clamp is a hose clamp which has a hex-head shape with a flathead mark on it. The other is a spring clamp with two metal tabs extended out that, when clamped together with pliers, releases pressure on the lines.
- Unbolt the EGR valve from the EGR tubing, using the open-end wrench. Turn the bolts on the EGR valve counterclockwise with the wrench to loosen them. Remove the EGR valve from the vehicle.
