Filling Radiator with Engine Coolant
Fill the radiator and reserve tank as follows. This procedure is for
filling the radiator for the first time or refilling it after it is flushed.
Note that a typical radiator is illustrated (Figure 42).
1. Check to be sure the radiator drain plug is installed and
tightened or the drain cock (1, Figure 42) is closed. Also
make sure the coolant drain plug (1, Figure 43) in the
cylinder block is closed or the oil coolant hoses (1, Figure
44) are installed at the oil cooler.
2. Remove the radiator cap (2, Figure 42) 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 (2, Figure 42). 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 (3, Figure 42), and fill
it to the LOW (COLD) mark (4, Figure 42) with engine
coolant. Reinstall the cap.
6. Check the hose (5, Figure 42) that connects the reserve
tank (3, Figure 42) 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 (6, Figure 42). If the engine coolant is
not at the FULL (HOT) mark (6, Figure 42), add additional
engine coolant to the reserve tank to bring the level to the
FULL (HOT) mark.
