It has been a number of years since I have had the need to do a through =
cleaning and flush of the coolant system, my earlier 71BGT being one car =
in particular. So I am not sure how dated this is but there is or was a =
cleaning kit available at car parts stores that contained oxalic acid =
(crystalline form) that was poured into the radiator. Then the car was =
driven for 10-15 minutes, the coolant drained, and the system flushed. =
There was also a flush kit available from Prestone that introduces a tee =
in the heater to engine block hose that allows you to connect a water =
hose to it. With a hose connected and on, radiator cap removed, the =
system was flushed until the water was clear. I think the last time I =
used this method was on a Chevy S10 about 15 years ago.=20

I've often wrestled with this. I usually flush debris out by running the =
engine and flowing water through. However, any system that flushes tends =
to put the output debris in the radiator! How about disconnecting the =
TOP hose, feeding fresh water into the radiator, and ducting the output =
from the waterpump into a bucket? Anyone tried this?
