Good day all,
For the first 3 years I sent my coach out for the PM. So I never attempted this on my 1999 Monaco Executive with side radiator and a M11 450hp Cummins. I am about to change the oil to Valvoline Blue (10.5g), lube & all new filters. I also want to flush the cooling system and replace the antifreeze with Fleetguard ES Complete OAT. However, I cannot find out have many gallons are in the cooling system? Any help or comments would be greatly appreciated.
Thanks and as always safe travels,
