2. Remove the radiator cap (Figure 4-7, (2)) by
turning it counter-clockwise 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 4-7, (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 on the reserve tank
(Figure 4-7, (3)), and fill it to the LOW (COLD)
mark (Figure 4-7, (4)) with engine coolant.
Reinstall the cap.
6. Check the hose (Figure 4-7, (5)) that connects
the reserve tank (Figure 4-7, (3)) to the
radiator. Be sure it is securely connected and
there are no cracks or damage. If the hose is
damaged, the engine coolant will leak out
instead of going into the reserve tank.
7. Run the engine until it is at 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 tank should
be at the FULL (HOT) mark (Figure 4-7, (6)). If
the engine coolant is not at the FULL (HOT)
mark (Figure 4-7, (6)), add additional engine
coolant to the reserve tank to bring the level to
the FULL (HOT) mark.
