Over heating -- cause found

[Pete Masterson]

No... the Wanderlodge pushers have the radiator to the left side (as
you face toward the front) -- since the beginning as far as I know..
Of course the FC units have the radiator in the front. DD 6vxx and
8vxx engines are noted for small oil leaks and mist, so any road dust
gets mixed with the oil and starts to coat the radiator.

The simple green - pressure wash idea is probably a good one (almost
any detergent that's gentle on aluminum would do). However, it is a
procedure that should be started early ... after eleven years of
accumulation (as in my case) has occurred, a jack-hammer is probably
a better tool.

With the radiator out of my coach, you can see that the engine,
particularly on the radiator side, is also coated with a fair amount
of the oil-dirt crud. The radiator shop will steam clean everything
before reassembly.
