Engine/Transmission (1994 - 1998) proper coolant ?

[DBentley]

I replaced my radiator and t stat with updated type and used regular prestone anti 50/50 mix a few months ago. Is prestone ok for our diesel engines?

i use the fleetguard ec compleat from the cummins store in columbus, indiana. or i use the rotella from the truck stop. both are for diesels and are premixed.

Prestone's just fine, ran it in my 3 previous CTD's and will run it in the'03 after the fisrt change, probably next spring.

Because we do not have a sleeved diesel engine, the Prestone is fine.
