1998 Jaguar XK8 Q&A
1998 Jaguar XK8 Question: Coolant low indicator comes on a lot.
I would suspect the water pump shaft seal that at times will leak and then not leak depending on engine temp and therefore seal swell and shrink. Common on lots of vehicles. Could also have slight seepage at the head gasket again depending on engine temp as head swells and contracts. Have the compression tested and pressure test engine at different temps. - raiderron
