The steps below to add coolant to the radiator and sub-tank. This step is the first time you add coolant to
the water tank or add it again after the water in the water tank is drained. The picture below shows an
ordinary water tank.
1. Check to confirm that the drain plug or drain faucet of the water tank (Figure 5, (1)) is installed and
tightened. At the same time, confirm that the coolant drain plug of the cylinder block (Figure 4-6, (1))
is
tightly closed or the antifreeze pipe has been installed.
2. Turn counterclockwise 1/3 turn to remove the water tank cover (Figure 7, (2)).
3. Slowly add engine antifreeze into the water tank until the liquid level is level with the water filling
port. Make sure no bubbles form when adding.
4. Tighten the water tank cover (Figure 7, (2)). Align the mark on the back of the tank cover with the
notch on the edge of the addition port. Press down on the water tank cap and turn it 1/3 turn clockwise.
5. Remove the water tank cover (Figure 7, (3)) and add engine antifreeze to the lower limit (cold)
position (Figure 7, (4)). Put the lid back on.
6. Check the pipe connecting the water tank (Figure 7, (5)) and the radiator (Figure 7, (3)). Make sure
it is well connected and not pinched or damaged. If the pipe leaks, the antifreeze will also leak and not
flow to the radiator tank
. 7. Start the engine until it reaches operating temperature. Check the coolant level in the auxiliary tank
.
While the engine is running, check the antifreeze level. When the engine coolant is at normal
temperature, the coolant level in the auxiliary tank should be at or close to the full (hot) position.
(Figure 7, (6)). If it is not in this position, add coolant to the auxiliary water tank until it is full.
