Fleetguard PG vs EG
« on: January 15, 2017, 09:21:02 AM »
8.3 Cummins Mechanical

1. I bought this rig a few months back. The coolant is Fleetguard ES Compleat PG. I am having a tough time finding any of this stuff. Everyone stocks EG instead. Can these two ELCs be mixed?

2. I queried PG and see that its advantage is that it's more environmentally friendly than the ethylene stuff. I also noted that Fleetguard mentions using a coolant filter that injects DCAs. This rig has been maintained by Cummins and they did, in fact, install that type of coolant filter. I thought the ELCs just used blanks so that's what I replaced it with. Anyhow, shouldn't this coolant use a blank filter?

Welcome to the diesel RV Club.

Here is a Cummins/Fleetguard pdf document:

Though it states "compatible with all other coolants" for both, I would probably contact Fleetguard by phone or e-mail:

BTW, will be out your way the end of the month in our coach, then up to the Diesel RV Club Rally in Camp Verde to do their Maintenance Seminars.
