I seem to be losing water a lot from the radiator reservoir but my engine doed not over heat at all. The pipe from the radiator to the head is very tight and seems to have no play when you squeeze it. Also when I undo th ewater cap to fill up the water it de compresses and fills with water again. The water is clean and there is no water in the oil and I am worried this is a problem with the head. Could you share any light into this problem for me please?

Hi there, best you get the cooling system fully checked first, make sure that there are no external leaks, the pressure cap is ok, radiator & thermostat are functioning correctly and get a head check done, this will check for exhaust gasses in the cooling system, a sure sign of a head problem, start here.
