Belt - Inspect
Illustration 61 g03073936
Typical example
To maximize the engine performance, inspect the belt
(1) for wear and for cracking. Replace the belt if the
belt is worn or damaged.
• Inspect the belt for cracks, splits, glazing, grease,
displacement of the cord and evidence of fluid
contamination.
The belt must be replaced if the following conditions
are present.
• The belt has a crack in more than one rib.
• More than one section of the belt is displaced in
one rib of a maximum length of 50.8 mm (2 inch).
To replace the belt, refer to Disassembly and
Assembly, “Alternator Belt - Remove and Install”. If
necessary, replace the belt tensioner. Refer to
Disassembly and Assembly, “Alternator Belt -
Remove and Install” for the correct procedure.

Coolant (DEAC) - Change
• DEAC Diesel Engine Antifreeze Coolant
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
NOTICE
When any servicing or repair of the engine cooling
system is performed, the procedure must be per-
formed with the engine on level ground. Level ground
will allow you to check accurately the coolant level.
This procedure will also help in avoiding the risk of in-
troducing an air lock into the coolant system.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. This inspection is a good opportunity to
replace the water pump, the water temperature
regulator, and the hoses, if necessary.
Drain
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
1. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly in order
to relieve any pressure. Remove the cooling
system filler cap.
Note: Refer to Operation and Maintenance Manual,
“General Hazard Information” for information on
Containing Fluid Spillage.
