Removing the EGR valve from the 2.8-litre diesel engine in a Jeep Liberty can be time-consuming. Fortunately, with a little effort and a lot of patience, you can do it yourself and save on an otherwise large repair bill. The EGR valve is located on the back of the engine, just below the intake manifold on the driver's side of the engine. The valve bolts in place with four 8-millimeter bolts that are hidden below the manifold, so you will not be able to see them.
