I recently aquired a very good condition F78 1995.It however
overheats on normal or motorway long inclines while towing my lightweight Caravan(Max Gross Weight 1045Kg.) Driving solo there is no problems which seems to rule out the thermostat.It does have an A-Bar with 2 Cibie Oscars driving lamps, could these be restricting the airflow to the radiator? I would appreciate any
pointers from the more experienced owners in order to resolve the problem.
