MAINTENANCE/SERVICE


Engine Cooling System


CHANGING COOLANT

Coolant should be removed, and the system
flushed and filled with new coolant every 2000
hours or 2 years.

Procedure:

CAUTION: To avoid personal injury
from hot coolant, do not turn radiator
cap until engine cools. Turn the cap
to the first notch to relieve pressure

before removing cap completely. Use a ladder
as shown on previous page to access radiator.


1. With engine cool and approximately level,

remove radiator cap.


NOTE: A drain pan with a capacity of 8 U.S.
gallons (30 litres) will be adequate.

2. Remove drain plug (B) from engine block.

3. Open radiator drain valve (C) at near lower rad

hose. Use a deflector to prevent coolant running
onto frame.


4. When system is drained, replace drain plug in

block and close radiator drain valve.


5. Fill system with clean water and replace

radiator cap.


6. Open heater valve (D). Turn heater switch in

cab ON and leave it on until flushing is
complete.


7. Start and run engine until normal operating

temperature is reached.


8. Stop engine and drain water out before rust or

sediment settles.





















9. Close drain valves and fill system with a

solution of clean water and a heavy duty
radiator cleaner. Follow instructions provided
with cleaner.

10. After using cleaner solution, again flush system

with clean water. Inspect radiator, hoses and
fittings for leaks.

11. Close drain valves and fill system through radiator with a 50/50 mix of anti-freeze and clean, soft water.
