Jim Galbally - No problems as such with the car. When I got the car the water was like a brown paste so I have done 3 full flushes on it now and seems to have cleared. I thought after seeing the state of the water it would be best to change the thermostat to so i did but when i removed the housing there was nothing there. This then sparked the confusion into the thermostat removal :-(
