oh, oops.  Guess I should have explained that part.  Actually, draining out
the coolant in a controlled fashion is relatively difficult since it is hard
to pull the hose part way off to drain slowly.  Ever try to save recently
replaced coolant for re-use before?  Its a PITA, trust me :-)

Anyway, to answer that question just pull the hose on the radiator side that
connects to the t-stat housing.  That will drain almost all of the coolant
out. The rest will come out when you pull the t-stat itself.

not to the block.  No way a garden hose will damage anything by blasting at
full power into the filler neck.  By the time the water reaches the heater
core it will not be packing nearly as big a wallup.  When flushing the
radiator you might want to use more caution of course.

If you flush your radiator and it causes a leak you either hit it with WAY
too much pressure or it was going to leak anyway (or already was?).
