CHECK COOLANT LEVEL, ADD COOLANT
WARNING
q
Do not open the radiator cap unless necessary. Wait for the engine to cool down before checking the
coolant in the sub-tank.
q
Immediately after the engine is stopped, the coolant is at a high temperature and the radiator is under
high internal pressure. If the cap is removed to check the coolant level in this condition, there is a
hazard of burns. Wait for the temperature to go down, then turn the cap slowly to release the pres-
sure before removing it.
1. Open up inspection cover (1) on the right side of the truck
to check if a cooling water level in sub-tank (2) remains
within the FULL - LOW range. If not, refill the tank with
clean water up to the FULL level through the filler port in
sub-tank (2).
REMARK
In summer, the coolant may overflow from the sub-tank drain
hose. This is no problem. It occurs because too much coolant
has been added.
2. After adding coolant, tighten the cap securely.
3. If the sub-tank is empty, check for leakage of coolant, then
add it to the radiator and sub-tank.
4. After adding coolant, close the engine side cover.
