22. TRAVEL OPERATIONS
n CHECK COOLANT LEVEL
• Normally, do not open the radiator cap. Check the coolant when the engine is cold, and check
using the reservoir tank.
• NEVER remove the radiator or sub-tank cap when the coolant is hot. Boiling water may
spurt out.
• When removing the radiator cap after the coolant temperature has gone down, turn the cap
slowly to release the pressure before removing it.
NOTICE
Even if coolant level in sub-tank is normal, check radiator coolant level every month or 200 hours on hour
meter. If radiator coolant level is lower than specified, that may make overheating likely.
Check radiator and hoses for any water leakage.
Check that coolant in reservoir is cold, and add coolant to MAX
level.
If reservoir is dry, add coolant to radiator and then to reservoir tank.
Also check deflection of V-belt. (See "CHECK DEFLECTION OF
DRIVE BELT" on page 3-23.)
n CHECK ABNORMALITIES FOUND ON PREVIOUS DAY
If any abnormality was found during the checks or operation on the
previous day, check that the repairs have been carried out and that
there is no abnormality.
NOTICE
On LPG trucks, open the Fuel Service Valve, on the tank, by turning it gently counterclockwise.
Turning the valve clockwise shuts off the LPG flow to the engine.
