Hot engine

[eagle19952]

Excuse my ignorance but if the engine is overheating, doesn't that mean something is mechanically wrong?  I understand doing things to mitigate it but aren't they built to run in all temps day and night? 

no.

neither was your Desoto.

Most should run all day without overheating with the stock injectors, all shrouds in proper locations, bottom air deflectors in place, clean radiator,s.
Very few older models are still running stock injectors or have a like new radiator, etc.

John,
My coach doesn't have  transmission temp gauge. The manual mentions one but does not show in the diagram.

UPDATE:
Found a reference to the trans oil temp going to the oil temp gauge. Next visit to the bus, I'll have to check this out.

"Very few older models are still running stock injectors or have a like new radiator, etc."
I'm curious as to why you think that?

Most of the older 8-v71's, at least ,have had their injectors upgraded at least one size larger. How many have near new radiators with no build up in radiator or block. Highway speeds are higher and most run at higher speeds. On grades we try to keep up with traffic that is moving faster now. The harder you work a diesel, the more heat it creates.
