LOW COOLANT LEVEL.
If vehicle has been operating, use extreme care to avoid being burned when removing radiator
cap or coolant reservoir cap. Sudden release of pressure can cause a steam flash which could
seriously injure personnel. Use heavy rags to protect hands. Slowly loosen cap to the first stop
and allow pressure to be relieved before removing cap completely. After use, securely tighten
cap. Failure to comply may result in injury or death to personnel.
Coolant may damage the skin. Wear protective equipment and avoid skin contact when handling
coolant.
Step 1.

If radiator hose(s) are damaged, replace radiator hose(s) (Para 9-5) and top off coolant level
NOTE
