[MR2] Coolant Level

You will note that the coolant reservoir is very large. If it was filled to
the proper level to start, it will suck up several ounces of coolant every
cool down cycle until it gets full. If you measure about a foot down from
the cap (assuming its like the turbo bottle) and make a mark on the
dipstick, you'll be in the ball park for "full". Most older MKII reservoirs
have a couple ounces of difficult to remove crud. I use a small water pump
to suck dry, add a couple quarts of a good crud remover solution, sit over
night and flush with a small hose and running water (yes Virginia, it makes
a mess in the drive way) until the water runs clean. Then I add a 50/50
coolant mix until it hits that full mark. Then topping the "radiator" cap
and cycling does the trick. I do this each time I do a cooling system
flush. 30,000 miles or so.
