How do I Change the Fuel/Water Separator on a Jeep Liberty Diesel?
Replacing the fuel/water separator on the 2.8-liter diesel engine in your Jeep Liberty is not something that you need to do regularly, but when the time comes, a new separator assembly is available from the Jeep dealer. The fuel/water separator is important, as it works to remove moisture and sediment from the diesel fuel before it enters the fuel rails and engine. Water can damage the engine and cause it to run poorly or not at all.
