Windsor cooling volume

[hwbuck]

Does anyone know the volume of a 1999 Windsor 40' standard side radiator cooling system? Cummins 350

Any specific tips on changing antifreeze to final charge?

thanks

Have no idea about volume but in changing ours we disconnected the heater hoses at the front "radiator" and blew them out (1+ gal). We "flushed" 4 times until only clean water came out. Suggest at least one gal. of 100% Final Charge (hard to find) so that any residual clear water will not dilute the mixture to less than the 50/50 premix. Book says 40 to 60% mix is OK BUT............
WalMart had a 15 gallon metal wash tub for $9.00 - Volume was pretty easy to figure as "volume out = volume in". The tub is now used for oil changes

Last time I changed mine I bought 6 gal non diluted HD prestone ( mix with any) and 6 pints of CDA4, three coolant analysis strip packages (9 total strips) and one gal of Restore plus to flush. I had a little left over DCA4 and antifreeze. Follow directions.
