Draining the Radiator
See Figure 7-7, Figure 7-8, and Figure 7-9 for the following.
Drain the radiator system as follows.
1. Stop the engine.
2. Remove the covers over the three bleed valves—two at
the front of the radiator and one at the rear of the
radiator.
3. Open the three bleed valves.
4. Remove the radiator surge tank fill cap.
5. Open the drain valve and drain the coolant into a
suitable container.
6. Close the drain valve once the system is completely
drained.
Filling the Radiator
Check the SCA concentration according to the schedule in
the engine manufacturer’s operator manual and to the
warnings, cautions, and instructions in the engine
manufacturer’s service manual.
Add coolant to the Full Cold mark as determined on checks
per the schedule in the engine owner’s manual.
1. Fully open all three air bleed valves.
2. Fill the cooling system through the radiator fill cap to the
Full Cold mark on the sight gauge. The coolant system
capacity is approximately 80 L (21 gal).
3. Observe and close the bleed valves once clear coolant
appears at the bleed valves.
4. Continue adding coolant until the level is at the Full Cold
mark.
NOTE: The maximum fill rate is 19 L/min (5 gpm).
5. Install the fill cap and run the engine until it is at normal
operating temperature.
6. Look for coolant leaks while the engine is running and
correct causes of leaks if any are found.
7. Stop the engine, wait until the engine is cool, and refill
the radiator to the Full Cold mark.

CAUTION
Engine Damage!
The required supplemental coolant additive (SCA)
concentration must be maintained to prevent engine
damage.
An SCA must be added to the cooling system to prevent
liner pitting and for scaling protection.
CAUTION
Engine Damage!
Engine castings can be damaged if cold coolant is added
to a hot engine.
Allow the engine to cool below 50°C (120°F) before
adding coolant.
