They are both ES Compleat. One is Ethylene Glycol (50/50) and the other is Propylene Glycol (concentrate). This is what I've found online. I think i'll just carry some of the Ethylene Glycol.
I didn't realize that. I have CC2835 polypropylene glycol
In the past I used Propylene ES Complete for mains and the genny. During the last service, my mechanic suggested that according to Cummins, Propylene is made for mains and Ethylene is for genny. If you don't have access to both, it's ok to to use Propylene ES Complete for mains and the genny.
I was always using Fleetguard test strips and they don't call for any specific type of coolant. Thus, I always considered it as valid.

Are you going to do this yourself? Knock on wood but ours are doing fine but.... they do not last forever.
I was able to remove the pump on the port side without too much of an issue. I did remove the exhaust tube this past winter while the boat was out of the water for another project. with 2 people its an easy job. Not sure of water level in there though if its in water. The starboard side you would have to remove the exhaust tube to work on it. Haven't had to touch that fortunately but if I do. I'm also replacing that water heater. at the same time.
No I am not doing it, got a great boat mechanic.!
Exactly why we replaced the VF with macerating toilets. The VG’s were just not serviceable where SR put them. To safely remove the exhaust you should be hauled out...or remove the tube then plug the through hull. It is technically above the water line but not by much.
When we bought the boat both heads needed a rebuild. No problem. I did that myself before leaving FL for MD. A day before we were supposed to leave, the stbd side clogged and the vacuum pump failed. Later that day the port side VG refused to hold vacuum. The port side VG wasn’t getting fixed without removing the exhaust. The quote to deal with the VG’s was only $2500 less than replacing the whole mess with macerating toilets. Best money spent on the boat so far.
