Are you sure you aint got a water leak somewhere? I had a nightmare with my road one it decided to overheat while cruisin (ha) on the M25. Turned out to be a high pressure leak from the header tank!tonyr wrote:ive got big problems with my cooling system,around town its fine and the needle stays in the middle of the gauge,but as soon as you go on the motorway thats it ,the needlde shoots to the red and thats when i have to put the heater blowers on full to cool the system down.
