when my 7.5 tonn horsebox an iveco is park up in the barn there is a small water leak my levels are all fine and do not need topping up when stood it does dry up I have crawled underneath and can see no drips....help is it major
Possibly a very small leak from the water pump which only happens when the engine is warm and things expand. When parked up and the engine cools the leak stops. Have a look for any dripping after the engine has had a good run.
