3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, and then securely close the drain
cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Slowly fill the radiator with the proper coolant
mixture (see the "Recommended Engine
Coolant in previous page) until the fluid level
stays up in the radiator neck. And pump the
radiator hose in order to bleed the air.

2. Wrap a thick cloth around the radiator cap
and slowly turn the radiator cap counter-
clockwise without pressing down on it, until
it stops. This relieves any pressure remain-
ing in the cooling system. When you are sure
that all the pressure has been released,
remove the radiator cap by pushing down
and turning counterclockwise.

6. Run the engine at idle until the coolant circu-
lates. If the cooling fan operates and the
coolant starts to circulate, add the coolant to
the reservoir.
7. To bleed the air in the cooling system, repeat
procedure 6 until the cooling fan operates
3~5 times.
8. Replace the radiator cap and turn it until
tightly installed. And then, add coolant to the
reservoir until the level is between "L" and
"F".
9. Stop the engine and check the coolant level
when the engine is cool. The level of the
coolant should be the "L" and "F" lines on the
reservoir. If the level is below the "L" line,
repeat the procedure 4~8 until the level
between "L" and "F".
