3. Only when the engine is cool, attach a
small hose to the drain tube at the bot-
tom of the radiator. Loosen the radia-
tor drain plug. Drain the coolant into
a suitable container.
4. With the drain plug loose but not fully
removed, flush out the system with
running water.
5. Drain the system completely and
retighten the plug. Add a 50/50 mix-
ture of coolant and water as necessary
to provide freezing and corrosion
protection. When cold, fill the radiator
to a level 1 to 1 1/2 inches (25 to 38
mm) below the filler neck seat.
Maintenance
In extremely cold climates, add the
amount recommended in the coolant
manufacturer's instructions.
6. Replace the radiator cap to its fully
installed position, then back it off to
the first stop. This will prevent high
pressure from building up in the cool-
ing system during this part of the pro-
cedure.
