certainly need at the minimum the cooling system flushing and then topping up. The gasket could have gone if there was little to no coolant, so you would be best to replace that as a matter of course if you feel confident enough to do it!
That would be the starting point and then diagnose further from there.
normally if the water/fluid is on the outside of the engine block it is more likely the pump gasket, what is the cap that you have taken off?
there was a black plastic round lid to the motor mount as in the pic
when driving all seems ok when the coolant level is full the temp runs at half way.
there is no leak when the engines off
theres no gunk anywhere
if I fix it I keep it if not its scrap but my gut feeling is its werth fixing
think ive made somewhere now another day fiddling. after visit to the local ford breakers ive now found that after a coolant pressure test the HG is ok. phew!! The coolant leak is coming from where the two rubber hoses join from the radiator is it thermostat housing?
is it easy to change?
