At work we have a Freightliner with a CAT C7 engine and I have been using genuine CAT ELC coolant in it. The coolant is a bit expensive.
I can get the Prestone coolant for about a third of the price of CAT coolant.

The Prestone coolants are on sale at Fort Garry Industries

Any downsides to using the Prestone coolant?
