Had the engine running for over 15 minutes today, wanted to check that the Kenlowe cut in. Seems like the thermostat is stuck open because both the top and bottom radiator hoses were warm to touch and the fan never came on. The temp gauge never got much past 1/3. If fitting a new themostat warms things up I will be happy.
PS The new thermostat and gasket arrived over night from S&S Preparations - great service. No Xmas delay in the post from Bacup to Newark.
