FW: Type-44: 200q cooling system flush/fill tips.

[Livolsi, Stephane]

I am skeptical about the concerns with 'blasting away'.  With the pressures
that build up in the system at high temps, I can't see how a garden hose is
going to do any damage.  If blasting inside your rad with a garden hose
damages anything, I think it was well on it's way out anyway and better to
find the weakness now than out in the middle of nowhere, in the middle of
winter, at -30 degrees, wearing only a tshirt and runners, with no cell
phone..... (don't ask, OK?)
