WB-40 Cooler Configuration

Curt:
After Pete had his temp problem it inspired me to take a close look an
my coach. Your set up may be similar, don't know. This is what I
found. The Hayden oil cooler in front of the radiator street side cools
the oil used for power steering and the water radiator cooling fan. The
transmission, retarder and the engine oil are independently attached to
the water cooling system via heat exchangers(I think that's the term)
The engine oil heat exchanger is bolted to the side of the block and
has a drain on the bottom. I'm not certain how the trans and retarder
cool. However, the coolant lines are attached to both. None of the
coolant lines is attached directly to the radiator but are routed off
of a collection tank or manifold.
