Well someone has, judging by my experience, as the radiators
usually dissolve from the outside in about eight years, and the water
pump and hose give up at about the same interval. I usually got a freeze
plug job from people whom didn't change their coolant in about four
years. Of course that's topping off with our California's hard water.

Not for Jeeps but VW/Audi use 2 proprietary coolants possibly made by by
Valvoline.
This coolant should not be mixed with any other coolant or it will sludge up
pretty bad.
Now VW has a "Universal" coolant that can be mixed with either of their
coolants.
So the tally is up to 6-7 different coolant types. ;-)

I have seen this before, thick and kinda grayish-black, and I attributed it
to never changing the coolant and mixing different types together. I also
noticed that this solution ate up the metal sensor bung inside of the black
plastic radiator in a VW. Engine was fine and kept running for years until
another vehicle took it out.

It used to be a time that you were suppose to change the coolant every two
years along with a proper flushing.
Of course it was also recommended that you change the motor oil every 2-3
months too! lol
Times have changed some..........
I know that certain oil filters (VW and Audi) have recommendations that you
can change them every 2 years or 24,000 miles. Of course you will need very
good synthetic oil too! ;-)

This some nasty stuff I had to flush out.

One out of many daves did pass the time by typing:

One other possibility is that goo was several tubes of stop-leak or such
radiator killer in a tube. I've seen that before at some shady used-car
dealers.

Well it should not have been on this vehicle. I knew it since it was new,
so the only other way it could have gotten in the system is by the hands of
the dealer techs. It seemed more like something was disintegrating or
dissolving in the cooling system. Might have been the water pump now that I
think about it, but it should not have caused the radiator sensor bung to
erode.

mystery! lol
