2 Inspecting and Flushing the Cooling System
2 Inspecting and Flushing the Cooling System
The cooling system must be full for proper operation of the engine.
WARNING: HOT COOLANT
To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap
while the engine is at operating temperature. Wear adequate protective clothing (face shield,
rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure.
Check the coolant level daily and maintain it between the full and low marks on the surge tank. Add coolant as required, but
do not overfill.
Make a daily visual check for cooling system leaks. Look for an accumulation of coolant when the engine is running and
when it is stopped. Coolant leaks may be more apparent on an engine when it is cold.
The inhibitors in antifreeze solutions must be replenished with an approved corrosion inhibitor supplement when indicated by
testing the coolant.
NOTICE: Coolant must be inhibited with the recommended Supplemental Coolant Additives (SCAs) listed in this
guide. Failure to check and maintain SCA levels at required concentrations will result in severe damage
(corrosion) to the engine cooling system and related components.
The cooling system is protected by an SCA element. In addition, the engine can be equipped with a coolant filter/inhibitor
system as an installed option or as an after-sale item.
A coolant system properly maintained and protected with supplemental coolant inhibitors can be operated up to the intervals
listed. At these intervals the coolant must be drained and disposed of in an environmentally responsible manner according to
state and/or federal (EPA) recommendations.
Install a new cooling system filter at intervals defined in the Maintenance Intervals.
The DD Platform engine is equipped with a coolant filter. The coolant filter contains supplemental corrosion inhibitors.
Service the cooling system as follows:
1. Check the filter housings for signs of leakage.
2. Inspect the coolant in the surge tank for signs of contamination.
3. Is the cooling system contaminated?
a. Yes; Go to step 4.
b. No; ensure the coolant level is correct and release the vehicle.
4. Drain the cooling system. Refer to section "Cooling System Drain Procedure".
5. Remove the coolant filter. Refer to section "Removal of the Coolant Filter".
6. Does the coolant filter have a build up of gel or white residue?
a. Yes; Refer to 13TS-19.
b. No; Go to step 7.
7. Refill with soft, clean water and a cleaning system compound.

WARNING: ENGINE EXHAUST
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area.
Engine exhaust is toxic.
WARNING: PERSONAL INJURY
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level
surface, parking brake is set, and the wheels are blocked.
8. Start the engine and operate it for 15 minutes after the thermostat has opened to thoroughly circulate the water.
9. Stop the engine and allow it to cool. Drain the unit completely.
NOTICE: If the engine is hot, fill slowly to prevent rapid cooling and distortion of the engine castings.
10. Refill the cooling system slowly with clean water, start the engine and operate for 15 minutes after the thermostats have
opened.
11. Stop the engine and allow it to cool.
12. With engine cool, drain the cleaner residue from the cooling system.
13. Install the coolant filter. Refer to section "Installation of the Coolant Filter".
14. Fill the cooling system. Refer to section "Cooling System Fill Procedure".
