That mud could be oxidation in which case I think that you'd have to do a
chemical flush.

Before you do anything, read my post titled DexCool - An Interesting
Article. It may explain (or at last help to clarify) the "problems"
associated with Dex-Cool.

Fair enough...But I think I'll repeat my question,
"what is the best thing to flush a Dex-Cool system with?" Meaning what type
of chemical, what brand, any specific procedures...etc etc,

I've never flushed a Dex-Cool system but for a regular system, I use
Prestone Heavy Duty Flush. Why not ask your dealer or failing that,
check on a Prestone or Texaco (manufacturer of Dex-Cool) web site?

Q: How do I flush my cooling system and install a fresh fill?
A: Using a chemical flush prior to the fresh fill of antifreeze/coolant is
an effective way to remove deposits from the cooling system. Prestone offers
several flushes that are designed for everything from routine maintenance to
lime or rust scale. All of these cleaners are compatible with the cooling
system components of any vehicle. We recommend the following: Use Prestone®
Super Flush for routine maintenance. Use Prestone® Super Radiator Cleaner to
remove corrosion and lime scale. Use Prestone® Heavy Duty Cooling System
Cleaner to remove the toughest rust scale deposits. If the directions on
each of these cleaners are followed correctly, the end result will be an
empty radiator and mostly water in the engine block and heater core. At this
point, use a mix of 50% to 70% Prestone® Antifreeze/Coolant and water. This
is easily accomplished if you know the capacity of the cooling system.
Example: If the owners manual of your vehicle indicates that the capacity of
the cooling system is 8 quarts, then you need to install 4 quarts of pure
antifreeze. Note: Once the desired amount of concentrated antifreeze/coolant
has been installed, the cooling system must be topped off with water to
ensure a complete fill. Prestone Products also offers a Flush N' Fill Kit
for backflushing the cooling system. This kit fits some cars and most light
trucks. This backflush will remove more deposits than the chemical cleaner
alone. If you are able to access the inlet heater hose on your vehicle, we
recommend that you use one of the cleaners and then backflush the system

I think flushing Dex-Cool out is just like flushing out any other coolant, I
could be wrong though.

OK, how about the recycling power flush systems that a lot of service people
are using now? Any opinions, good or bad?

depends on the tech that sets it up. inexperienced techs forget about the
heatercore path. other than that, i don't think that machine is available
for consumer rental.
