Coolant Refill Capacity

Yahoo Message Number: 97127
Recently the pump for the Aqua-Hot developed a leak and lost all my engine anti-freeze. Need to determine what refill capacity is so I can determine how much antifreeze to put in. Not certain if the system is totally dry, so plan to use concentrate instead of 50/50.

Guessing 15 gallons, but that is purely a guess. All my manuals are in the coach 120 miles away! UGH!

Thanks in advance.

If you are talking about your total engine coolant capacity (and I believe you are), I think it is a lot more than 15 gallons. My 42' Allure is 26 gallons, per the specs in the manual. This includes, of course, the engine, all the hoses, radiator, front heater and hoses, etc.

Hopefully someone with the same rig will respond.

Bob, when I drained my 40' Allure ISL 370 system, the manual states initial filling is 24 Gal. a Refill is 20.5 Gal. When I drained my system including engine by removing thermostat piping which is highest point, radiator and all heater hoses with the front of coach raised higher than the rear we couldn't get more than 13 gallons out. When I refilled with FINAL CHARGE Extended Life Coolant we also got 13 back in.

Hope this helps a little.
