1. When the engine is cool, remove the radiator cap.
•
Turn the cap slowly to the left until it reaches a “stop”. Do not
press down while turning the cap.
•
Wait until any remaining pressure (indicated by a hissing sound) is
relieved, then press down on the cap and continue turning it to the left.
2. Fill the radiator to the base of the filler neck and fill the engine
coolant reserve tank to the “MAX” mark.
•
Use a solution that is at least 50 percent antifreeze but no more
than 60 percent antifreeze.
•
Add enough water and Isuzu Long Life Coolant antifreeze
solution to provide the required cooling, freezing and corrosion
protection. Install the radiator cap and reserve tank cap.
3. Run the engine until the engine coolant temperature rises to normal
level, and idle the engine for 10 minutes.
4. Turn off the engine. Make sure that the engine is cool. Remove the
radiator cap and add engine coolant to the radiator until it reaches
the bottom of the filler neck. Fill the engine coolant reserve tank to
the “MAX” mark.
5. Install the radiator cap and the reserve tank cap.
Engine Coolant Replacement and Cleaning
Draining:
NOTICE: Dispose of and handle the waste engine coolant in
accordance with the specified method.
1. Check the engine has sufficiently cooled.
2. Remove the radiator cap.
•
Turn the cap slowly to the left until it comes to a stop. Do not
press down while turning the cap.
•
Wait until any remaining pressure (indicated by a hissing sound)
is relieved, and then press down on the cap and continue turning
it to the left.
3. Open the radiator drain plug and engine drain plug, and drain the
engine coolant.
4. Close the drain plugs.
CAUTION: The engine must not be started after the engine coolant
has been drained. Doing so may cause engine burnout.
Cleaning the Radiator Core:
As a radiator core blocked with dirt and dust will result in a reduction
of cooling effectiveness and the corrosion of the radiator core, it is
necessary to periodically wash out the radiator core with water.
NOTICE: When washing out the radiator core, take care not to
crush or damage the fin, etc.
