I have a 2001 foretravel u320, Winterizing, is it coolant or water that that is passing through the heater cores is the basement and in the coach for heat? I have rv antifreeze pumped to my sinks shower hot and cold. If the coolant is coming out of the hot water side it is my understanding that the aqua hot is winterized is this correct. Thank you for your help.
Coolant in AH
I also run anti freeze out of cold side.
Don't forget washer/dryer
Make sure to check the AH drains which are under my house batteries.
