Engine Cooling System

Checking Coolant Level

1. Perform the “Mandatory Safety Shutdown Procedure” on page 10.

2. Open the engine cover (J, Fig. 79).

Check the coolant level in the expan-

sion reservoir (H, Fig. 79). The expan-

sion reservoir must be 1/3 to 1/2 full

for a cold engine and 2/3 to 3/4 full for

a hot engine. Add coolant to the

expansion reservoir as required.

Note: Use a low-silicate ethylene glycol-

based coolant, mixed with quality water

and supplemental coolant additives

(SCAs) suitable for heavy-duty diesel

engines. See the engine manual for addi-

tional information.

Do not remove the radiator cap when the

coolant is hot. Serious burns may occur.

3. Slowly loosen the cap and allow pressure to escape.

4. Remove the cap and add coolant as necessary. See “Fluid Capacities/Lubri-

cants” on page 31 for coolant specification.

5. Reinstall the cap.

Cleaning Cooling System

1. Perform the “Mandatory Safety Shutdown Procedure” on page 10.

2. Allow engine to cool.

3. Open engine cover.

4. Clean radiator and oil cooler by blowing air/water through the fins.

Important: High pressure may bend radiator fins; proceed with caution. Blow

air/water in opposite direction of cooling fan to dislodge debris.
