Changing A/F in a 3208

[Eric Johnson]

Bruce, I've used Cat prediluted antifreeze since I bought the coach in 2000.
Cat says their
product has a usable life of 600,000 miles/6,000 hours/6 years but you must add
their
extended life additive package at 300,000 miles/3,000 hours/3 years to use it
this long.
Cat shops charge about $10/gallon bottle. I'll be changing out the system this
year.
Biggest problem I've had in the past is finding someone that will take the spent
antifreeze.

When I drain the system, I close the block valves on the circulation system and
drain the
radiator and engine block only. Volume comes to about 12-15 gallons. I figure
the
circulation system volume is negligible and don't try to drain it. I'm sure you
could blow
out the circ system with compressed air but I just haven't considered it worth
the effort.
