Re-installed my complete 216 rebuild about 8K back. All new
hoses of course, new stat, flushed and pressure checked
original radiator and heater core. I thought it made sense
to upgrade to the latest GM technology and use the Dex-Cool
that GM has been specifying for the last couple of decades.
As I posted to a buddy this morning, BIG MISTAKE!!!!
Been having little cooing system problems, like little radiator leaks,
heater core leaks, hoses vulcanized to the fittings and this
reddish brown sludge in the radiator.
Just now spent a couple of hours reading all the bad reports
from mechanics and radiator shops about Dex-Cool, and the
class action law suits that are pending.
I wish now that I would have done my ‘homework’ before
choosing Dex-Cool over plain old green EG.
The worst thing was the destruction of the pristine original
fire wall Mariner Blue paint. The radiator was leaking a
tiny bit at the top, just enough that the level only needed
topping off once or twice a year. But….those few drops were
enough that it was blowing back in a spray and the acid in
the Dex-Cool etched itself into the original paint.
Before being sprayed with Dex-Cool or early on:
