WB-40 Cooler Configuration

[jwasnewski]

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.

While my 'bird may be different ... when the radiator was opened up,
there was a transmission fluid heat exchanger in the lower end-piece
of the radiator. I didn't see how it was attached to the
transmission, but there were hose fittings on the outside of the piece.

(My retarder is the exhaust type, so does not have any cooling need.)

Pete:
Thanks for your input. I park my bus on concrete in a family owned park in
Historic DeFuniak Springs, FL. I walk around the bus and look for evidence on
the concrete. If I don't see anything on the concrete I get lazy. I went under
the engine area today and came out very happy. No leaks, just a little dust
that a water hose will clean. I never really considered how important a
radiator is to operating a bus. It is the truly the life line of the bus.
Thanks again.
