Newell Gurus

I recently did the coolant change out. To the best of my efforts, the system held right around 15 gallons of coolant. I originally said 14, but when I ran the coach for twenty miles on the road to open the thermostats, it held another gallon in the coolant surge tank.

Other posts on the forum indicate that the two strokes hold much more.

My 6V92 and my newer 8V92 both took around 24 gallons. I guess those series 60 engines really are more efficient
