Whilst investigating coolant loss, I noticed that when warm, a liquid was dripping from under my 1999 4.6 . The dripping was coming from a small rubber (drain) hose clipped vertically to the sump. The aircon was off and the ambient tempreature was 12 degrees (Swansea). Could this dripping be related to the coolant loss ? The system was pressure and compression tested 2 weeks and 1000 miles ago and it passed.
