I had some overheating problems with my Series 60 powered unit on my
homebound trip after taking delivery in Texas...
Upon opening up the radiator, it was found to be 2/3 filled with oily-
dirt pulled into the radiator. This could not be seen from the
outside due to the charge air radiator that's located in front of the
water radiator and it could not be seen from the inside due to the
metal shroud around the fan. The area under the fan was open and
clear -- it was everything else that was blocked up.
Although a simple cleaning of the radiator could have resolved the
problem -- I elected to replace the radiator core with a more
efficient design (since about 1/2 the cost was the labor to pull the
radiator).
My current temperature readings are quite similar to yours -- except
the water temperature has yet to go much above 180 -- and my retarder
is exhaust based, and doesn't have a temperature gauge.
When the radiator was replaced, the radiator service replaced the
cap ... it's rated at 15 lbs.
I do lose about 1 quart of radiator water each trip while using the
chassis heat. There's a minor leak somewhere, but I haven't found it
yet. When the chassis heat isn't used, then I don't seem to use any
radiator water. (I carry a couple of spare gallons of premixed
coolant along...)
