Important: Be sure to keep the engine
oil level between the upper and lower limits
on the oil gauge. Engine failure may occur
as a result of over filling or under filling the
engine oil.
6. Install the oil fill cap and close the hood.
Checking the Cooling System
Clean debris off of the screen, oil cooler, and front
of the radiator daily and more often if conditions
are extremely dusty and dirty. Refer to section on
Removing Debris from the Cooling System in
Cooling System Maintenance, page 52.
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the level of coolant in the expansion tank
at the beginning of each day before starting the
engine. The capacity of the cooling system is 9.6
quarts (9 l).
If the engine has been running, the
pressurized, hot coolant can escape and
cause burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam
to escape.
1. Check the level of coolant in the expansion
tank (Figure 25).
The coolant level should be between the marks
on the side of the tank.

2. If the coolant level is low, remove the
expansion tank cap and replenish the system.
Do not overfill.
3. Install the expansion tank cap.
Filling the Fuel Tank
1. Remove the fuel tank cap (Figure 26).

2. Fill the tank to about one inch below the top
tank, not the filler neck, with No. 2 diesel fuel.
