Driving home a few days ago my 1.8 Freelander started coughing a bit. Got home to find no water in cooling system and cream replacing engine oil. The K series strikes again. Called AA to get a tow to garage. AA diagnosed as head gasket gone to to stuck thermostat - overheating of engine etc. At no time did temp light come on or guage move from normal. AA guy told me there is some kind of conversion available that moves temp sensor to a new position on top hose. Any body know anything about it or where i might get one?
