Hi - to cut down on the daily running fuel costs of my 4.0, I just bought a 2nd jeep...a 1998 2.5L turbo diesel xj sport. Its the first diesel engine I have ever worked on.. the haynes manual is enroute, but in the mean time im trying to find the water seperator, to drain it as part of the service im giving it.. googles been sending me round in circles, so thought id ask for help here... does anyone know where the hell the water seperator is?.. and how hard is it to drain?. Any advice appreciated!.
