s type 2.7diesel only overheating when towing at a set speed.when showing over heating put foot down and temp goes down till we get back to steady speed
red warning light comes on if i dont put foot down when engine heat going up. temp. will return to normal for about a mile then up it goes again
why does this only happen when towing and after about 20 miles.i have just driven 60 miles without caravan no problem ?
