1. Dipstick
4. Remove dipstick and check oil level on dipstick.
The oil level should be up to the Full mark .
5. If the oil level is below the Full mark, remove the fill
cap (Figure 17) and add oil until level reaches the Full
mark on dipstick.

1. Oil fill cap
Do not overfill.
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 the section on Removing Debris
from the Cooling System in Maintenance.
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 10.0 quarts (9.5 l).
CAUTION
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 18).
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.
Adding Fuel
Use only clean, fresh diesel fuel or biodiesel fuels with low
(<500 ppm) or ultra low (<15 ppm) sulfur content. The
minimum cetane rating should be 40. Purchase fuel in
20
