Radiator Capacity

The problem with motor homes and coolant is there are three companies involved....engine maker, chassis maker, and coach maker. When I tried to find the capacity of my cooling system, I called all three (keep in mind it's the chassis maker that puts in the coolant). Answers varied from 24 quarts to 32 gallons. Actual capacity was between 15 and 16 gallons.

Coolant/water ratio is still 50/50.

“…but it did say not to exceed 50/50 on coolant/water.” That was written in 1990. Nowadays that may not be the answer. Ask a radiator expert.

Thank you very much, larger than I expected. I couldn't find that in my manuals, but it did say not to exceed 50/50 on coolant/water.

Around 10-12 gallons depending on how well you get the system drained. From the Monaco Manual, not a guess. :)
