2. Remove the radiator cap (Figure 5, (2)) by
turning it counterclockwise about 1/3 of a turn.
3. Pour the engine coolant slowly into the radiator
until it is even with the lip of the engine coolant
filler port. Make sure that air bubbles do not
develop as you fill the radiator.
4. Reinstall the radiator cap (Figure 5, (2)). Align
the tabs on the back side of the radiator cap
with the notches on the engine coolant filler
port. Press down and turn the cap clockwise
about 1/3 of a turn.
5. Remove the cap of the reserve tank
(Figure 5, (3)), and fill it to the LOW (COLD)
mark (Figure 5, (4)) with engine coolant.
Reinstall the cap.
6. Check the hose (Figure 5, (5)) that connects
the reserve tank (Figure 5, (3)) to the radiator.
Be sure it is securely connected and there are
no cracks or damage. If the hose is damaged,
engine coolant will leak out instead of going into
the reserve tank.
7. Run the engine until it reaches operating
temperature. Check the level of engine coolant
in the reserve tank When the engine is running
and the engine coolant is at normal
temperature, the coolant level in the reserve
tank should be at or neat the FULL (HOT) mark
(Figure 5, (6)). If the coolant is not at the FULL
(HOT) mark, add coolant to the reserve tank to
bring the coolant level to the FULL (HOT) mark.
Daily Check of the Cooling System
1. Check the level of engine coolant in the reserve
tank. When the engine is cold, the coolant level
in the tank should be at or slightly above the
LOW (COLD) mark (Figure 5, (4)) on the
coolant reserve tank.
If the coolant level is at the FULL (HOT) mark
(Figure 5, (6)) when the engine is cold, the
coolant will expand when it becomes hot and
possibly spray out of the overflow hose.
2. Add additional engine coolant to the reserve
tank if necessary.
3. Check the radiator hoses for cracks, abrasions,
cuts or other damage. Replace as necessary.
Engine Coolant Capacity (Typical)
Note: Capacities listed are for the engine only
without a radiator. Refer to the operation
manual provided by the driven machine
manufacturer for actual engine coolant
capacity on your machine.
