4. Cooling System Fluid
The engine cooling system fluid is a 50 - 50 mixture of
ethylene glycol and water for cold - weather protection.
To drain the cooling system; attach a hose to the drain
valve located at the engine block (Fig. 4. 7D1). Remove
the radiator cap. Turn the drain valve handle so that it’s
toward the valve outlet. To completely drain the radiator
open the drain valve located at the bottom of the radiator
(Fig. 4. 7D1).
To fill the cooling system; close the drain valve on the
engine block (Fig. 4. 7D1) and refit the radiator drain plug.
Fill the radiator with a 50 - 50 mixture of ethylene glycol
and water. Refit the radiator cap.
5. Fan Belt Tension
Check the fan belt tension midway between the fan pulley
and alternator pulley (Fig. 4. 7E1). Deflection should be
between 1/4 to 3/8 in. (7 - 9 mm). Ensure the Fan Belt
Guard is replaced after the tension check.(Fig 4. 7E2).
6. Fuel Filter Replacement
The fuel filter is located in the engine compartment on the
left hand side (Fig. 4. 7F). The fuel filter should be
removed every 100 hours and any water or dirt found in
the element drained off. Change the filter every 400 hours.
To replace the filter; close the fuel inlet line shut - off
located on the side of the fuel tank (Fig. 4. 7F). Remove
the filter element (Fig. 4. 7F). Lubricate the seal on the
new filter and install the filter hand tight. Open the fuel
inlet shut-off. It is not a requirement to bleed air from the
fuel system. Follow Section 3. 1 for starting procedures.
