4. When the system stops draining, close both draincocks as neces-
   sary.


5. Using a funnel if necessary, fill the reservoir tank with a 50/50 solu-
   tion of antifreeze and water. Allow time for the fluid to run through the
   hoses and into the engine.


6. Start the engine and let it idle about 10 minuets; add the
   coolant/water mixture up to the FULL level.


7. Tighten the cap.


8. Race the engine 2000-3000 rpms for about 5 minutes, then stop the
   engine.


9. After the coolant drops, remove the cap and add coolant to the FULL
   level again.


10. Securely tighten the cap again, then start the engine and check the
    level.

FLUSHING & CLEANING THE SYSTEM

Proceed with draining the system as outlined above. When the system

has drained, reconnect any hoses close to the radiator draincock. Move the

temperature control for the heater to its hottest position; this allows the

heater core to be flushed as well. Using a garden hose or bucket, fill the

reservoir and allow the water to run out the engine drain cock. Continue

until the water runs clear. Be sure to clean the expansion tank as well.

If the system is badly contaminated with rust or scale, you can use a

commercial flushing solution to clean it out. Follow the manufacturer's

instructions. Some causes of rust are air in the system, failure to change

the coolant regularly, use of excessively hard or soft water, and/or failure to

use the correct mix of antifreeze and water.

After the system has been flushed, continue with the refill procedures

outlined above. Check the condition of the radiator cap and its gasket,

replacing the radiator cap as necessary.
