radiator flushing for v8

[Steve Kramer]

In the last vestige of hope before buying the new radiator for my v8 - I
want to learn how to the flush the radiator.

The V8 has your typical all season anti-freeze in there.  Shellzone - green

I bought some antifreeze which is - supposedly top of the line . Dex-cool
(phosphate free) red in color

I've heard of other flush kits which bypass certain parts of the engine,
heater core.

I bought something called Prestone Super Flush and Super Flush Cleaner.
These are detergent flush cleaners.

The first one (super flush) I drain the system and then add this with water
and run the system for 10- 15 minutes - then drain.

The Super Flush Cleaner has me drain system - add this to a water mixture
with 2 bottles and run the system for 3 hours - then drain.


Has anyone had any experience with these products or am I going to do harm
to the Audi and should I just flush with water ?


Thanks as always
