Does any one know how much coolant is required for the UFO Chassis?

I changed mine 2 years ago, I bought 3 Gallons of Dexcool, and 10 gal of distilled water from Walmart. The main issue I ran into was, it would keep puking out the top of the radiator. It took a long time to fill the 40 foot heater hoses going to the front of the RV. I had a hard time getting all the air out, I spent 4 hours draining and refilling my coolant. (Fill-Puke-Fill-Puke) because of air pockets.

How did you maintain the 50-50 mix?

I guessed, I would add DEX if a lot of coolant puked out. After 2 years my temp stays around 203 degrees. Sometimes driving down the road it will climb to about 220 before the fan kicks in and drops back to 203.

Mine has always run up to 229 before the fan comes on. The last trip in 100 degree plus heat it went to 234. I added some coolant (1/2 Gallon) and washed the radiator as best as possible. I will see how it performs on the next trip and then change the coolant if necessary.
