92 Cummins in a Chevy Dually...
 

I took a 92 Dodge Cummins and put it in my 2000 Chevy Dually. So of course, I added guages, switches, fans, etc to it...

I was wondering what is the standard operating temp for this truck...new guage reads it getting up to 235 pulling up a grade (altitude is about 6,000 feet).

Anyone know if this is okay or not?

Where is your sender location? Thats a bit hot for any enegine, like head gasket and injector cup O oring melting hot.

thats way too warm. ive been having the same problem on my 95 too. its the lack of air flow you get through those with an itnercooler in the way. what radiator fan intercooler setup are you using?
