Just bought a 2002 Gulfstream Sun Voyager with a 8.1 Workhorse. The manual says this came from the factory with Dex Cool in the radiator and cooling system. Is this true ? I haven't heard a lot of good things about Dex Cool.

If it is a GM motor on your coach that is what they were using on their engines. I had a 2002 Cadillac with the NorthStar engine and that is what they used. Best anti freeze you can get on a GM engine.

Hello, I have a 2006 Sun Voyageur. Dex Cool is supposed to be in mine also. My mechanic advised me that Dex Cool was the correct stuff for this unit and all Workhorse. He specializes in Transmissions, clutches etc and has serviced my vehicles for over 25 years. Never steered me wrong yet so I go with his advice.
