(1) If the cooling water in the radiator reservoir tank is not within
normal range when cool, add water to the FULL line.
Always check the coolant level in the radiator reservoir
tank prior to beginning of daily operation of the truck.
In antifreeze is being used, pay careful attention to the ratio
of antifreeze and water when adding coolant.
If the reservoir tank is completely empty, first add water
directly to the surge tank. Then add water to the reservoir
tank.
Alway allow the radiator to cool down before adding water.
At the operating temperature, the engine cooling water is at
high temperature and pressure, so it is dangerous to try to
open the surge tank cap. Wait until the radiator is cool
enough to be touched by hand before opening the surge
tank cap. Loosen the surge tank cap slowly to release the
pressure, then loosen the cap.
After filling the coolant into the surge tank, check for
leakage for the radiator, radiator hoses and other parts of
the cooling system and also for traces of water leakage
under the engine.
(1) Stop the engine, pull out the dipstick and check the oil level.
(2) The oil surface line on the dipstick should be between H and L.
L
If below L, remove the filler cap and add engine oil through the
oil level.
Change the oil if it is marked dirty or discolored.
Oil level is to be checked with the truck placed at flat level
and at least 3 minutes after the engine stopped.
Do not touch hot components or allow hot oil to contact
your skin.
