I have noticed the last few months that my Water bottle seems to be losing water however it is not overheating , there is no water in the oil as the cap is clean so is the dipstick ? so I phoned Dean today to have it pressure tested all I need to do now is get the time to go to the garage , at first I thought it may have been the actual cap itself so I got a new one from paddocks but it still seems to be leaking not drastically but enough for the water to be on my mind ....... forgot to mention its a 2000 Land Rover Discovery 2 .
