5. Open the radiator drain cock to drain engine
coolant.
NOTE:
You can prevent splashes from draining engine
coolant by connecting a hose (commercially avail-
able with a 7 mm (0.28 in.) inside diameter) to the
drain cock nipple .
6. After the coolant has been completely drained,
close radiator drain cock.
7. Flush the cooling system.
Pour soft water (preferably after heating moder-
ately) through the pressure cap opening. Refit
the pressure cap tightly by turning it clockwise.
Lower the cab.
Start and run the engine until the coolant tem-
perature indicator on the multi-information dis-
play shows the 8th segment on the scale. Stop
the engine after 10 minutes and then drain out
the engine coolant. Take great care as the cool-
ant is very hot.
Repeat the above procedure until the water is
free of dirt.
For details on handling the multi-information dis-
play, refer to page 6-8.
CAUTION
If the radiator tubing is clogged or coolant is
more contaminated than usual, have your vehi-
cle inspected at an authorized dealer.

ted.
