Been going thru all the maintenance procedures on the "new" Allegro. One of the more perplexing of them is the coolant issues. Upon doing some searching I find that the special additives/filters for the coolant aren't needed if final charge coolant is used--

Our motorhome has been around 10 years--is there a way I can tell if the coolant has been changed over to the "good stuff"?

Freightliner (Gaffney) sells test strips for $2-3 that will check your coolant very quickly and that is the safest way to know what you have; or what needs to be added. But it does not identify the type of coolant.

What color is it?

Looks & smells like basic Prestone--

Been searching thru the archives for more info, seems like with all the issues with changing over-- sensors not working right, an all-day flush out procedure, no one knows where to buy Final Charge-- It'll just be easier to buy some test strips and a 4-unit filter and put on when I need to?

A lot of people have done it, including me.
If in doubt, just flush what you have now and then put finalcharge in.
I am running it in the coach ISM 500 and the Onan 10kW for last two years.
I use a 0 sca coolant filter and change it every year.
I will change finalcharge in 6 yrs and recharge after 3 yrs.
Gone are the days of coolant strips and changing coolant every 2 yrs....
