8. Inspection of sedimenter (Water/dust separator) [Diesel]
The sedimenter is built into the bottom of the cartridge-type fuel filter. The sedi-
menter warning indicator on the dash display will come up when water accumu-
lates in the sedimenter.
9. Inspection of radiator and reserve tank
1. Inspection of coolant level
The coolant level should be between
the
“FULL”
level and
“LOW”
level
positions of the reserve tank.
To replenish the coolant, remove the
reserve tank cap and pour the water
into the reserve tank. (The standard
cooling water contains 40% long-
life cooling water.) Do not pour water
over the
“FULL”
level when the
engine is cold.
2. Inspection for coolant leaks
1) Inspect the core and tank of the radiator for coolant leaks. Also check each
hose connection for leaks.
2) For LPG trucks, check the LPG regulator and connections for coolant leaks.
DO NOT remove the radiator cap from the radiator when the engine is
hot. When the radiator cap is removed, the pressure is released from the
system. If the system is hot, the steam and boiling coolant can cause burns.
WARNING
The periodic replacement interval of the coolant is once every 24 months.
ADVICE
ADVICE
● Loosen the drain plug of the sedimenter immediately and drain the
water when the warning indicator exists.
● The air in the sedimenter must be bled after draining the water. (Refer to
