Draining/Flushing Cooling System
1. Perform the “Mandatory Safety Shutdown Procedure” on page 14.
2. Wait until the engine has cooled.
Do not remove
radiator cap
when the coolant is hot. Serious
burns could result.
3. Slowly loosen radiator cap (P, Figure 105)
and allow pressure to escape. Remove cap.
4. Position a suitable collection container,
with a minimum capacity of 19 L (4 gals.)
underneath the radiator.
5. Remove radiator drain plug (X, Figure
106) underneath the radiator and allow the
coolant to drain into the container.
Important: Dispose waste coolant according
to environmental laws. DO NOT pour coolant
onto the ground or down a drain.
6. Replace the drain plug (X) and tighten
securely.
7. Fill the radiator with coolant.
Note: Use a low-silicate ethylene glycol-based coolant, mixed with clean water and
supplemental coolant additives (SCAs) suitable for heavy-duty diesel engines. See “Fluid
Capacities/Lubricants” on page 183, “Coolant Compound Mixtures” on page 189 and
the engine operation manual for additional information.
8. Reinstall radiator cap and tighten securely.
9. Start and run the engine until it reaches operating temperature.
10. Check the coolant level according to “Checking Coolant Level” on page 141.
Hydraulic System
Never use your hands to search for hydraulic fluid
leaks; use a piece of paper or cardboard to find
leaks. Escaping fluid under pressure can be invisible and can penetrate
the skin, causing serious injury. If any fluid is injected into your skin,
see a doctor at once. Injected fluid MUST be surgically removed, or
gangrene may result.
