2. After the coolant has drained, place a water hose in
the radiator filler neck and run water through the sys-
tem. When water is flowing from the block drain plug
port start the engine. When the water flowing from the
block port is free from coloration and sediment, stop the
engine and remove the hose. Allow all water to drain
from the system through the radiator drain valve and
block port.
3. Close the radiator drain valve and reinstall the block
drain plug. Slowly refill the system with a 50/50 solution
of ethylene glycol antifreeze and water. Fill until the
coolant level is approximately
4 cm ( 1.6 in ) below the
bottom of the filler neck. Do not fill beyond this level.
