> If you really love the bus consider getting rid of the original cooler.

No, even if you don't love your bus!  If you like we people who drive
auto-shift german vans, if you like old-school trannies, if you
believe in reusing old tools and not replacing, or if you like the
sun, blue skies, birds, cats.  SH*T, even if you like red-dyed-haired
presidents, replace that cooler with something that isn't a time-bomb.

Oh, I guess you could piously mix and maintain a perfect coolant
cocktail but, really, what the heck IS that?
