              Antifreeze
Content-Type: text/plain; charset="US-ASCII"

Any of the Diesel rated antifreeze products have wetting agents to reduce
cylinder liner cavitation erosion. "Water Wetter" not needed. Even the Zerex
G0-5. These agents also reduce surface tension and allow the coolant to flow
better. The down side is that if there is any chance of a leak, this stuff
will leak faster.

One thing to check on these radiator is the inside chambers. That housing on
the hose side will frequently crack inside. This allows some of the coolant
to enter and leave the radiator without actually traveling through it.

At this age the radiator is tired both on the inside and outside. After a
good cleaning it will become a leaker. The larger problem with any of these
cleaners is removing them. Some of them will damage the system if not
completely rinsed out. And what do you do with all that contaminated water?
Unless something happened like oil getting into the cooling system I don't
use any flush and clean products. Just change the coolant when needed and
you should have a sludge or corrosion problem to begin with.  Also be sure
not to have leaks. Systems that require regular additions will get messed
up. If the radiator can't cool it is probably time to just replace it.

  You can also run Redline Water Wetter, a cooling enhancer additive that
promotes slightly better heat exchange. It works.
