Hello I have from time to time left under the engine a stain, and since I have not seen anything I drove to AT… they have not found anything so from Ford they have told me that what leaks is cooling fluidity and it could be (in the worst case) the water pump, you have an idea if and how I can test this because that would be 450 € because they have to join the timing belt right away.
