I am losing water/coolant at a very slow rate, i rebuilt the the unit due to an overheating problem 4 months ago, head skimmed, all new gaskets including P, new rad last year.
Loss has occured during the cold snap, the coolant ratio is as spec and i cannot see any obvious places for the leak, clips all tight and pipes all in order, no fouling in the oil, no smoke and no loss of power...
A long shot i know but is there anything obvious that i am missing?
Thanks
Paul
