Rust Prevention
To keep engines operating at newness efficiency, all forms of
rust formation must be prevented. The formation of rust in
the cooling system is a result of the interaction of water, iron,
and oxygen, and can only be prevented by maintaining full
strength corrosion protection at all times.
For maximum rust, freeze, and boiling point protection, a 50/
50 fully formulated antifreeze coolant should be maintained
at all times. Failure to use and maintain the fully formulated
coolant will increase maintenance needs.
Engine Antifreeze/Coolant Fill Procedure
1. Fill the system with fully formulated antifreeze/coolant
mixture. Fill to the bottom of the filler neck. Open
petcock on top tube. Fill slowly. Flow exceeding 19 l/min
(5 gpm) can give a false reading.
2. Wait one minute and recheck the antifreeze/coolant
level. Refill as necessary repeating step 1.
3. Run the engine through two (2) thermal cycles and
recheck the antifreeze/coolant level. Refill as necessary
repeating step 1.
Cooling/SCA Maintenance Summary
The cooling system level should be checked every 10 hours
of operation or daily, whichever interval occurs first.
Supplemental Coolant Additives (SCA)
Supplemental coolant additives (SCA) are recommended for
this cooling system. Antifreeze alone does not provide
sufficient protection for heavy-duty diesel engines.
DCA4
DCA4 is the recommended SCA. Other brands can be used
if they provide adequate engine protection and do not cause
seals or gasket degradation or corrosion/fouling.
Coolant Filter
The Cummins engines have a coolant filter of the canister or
spin-on type that requires periodic servicing. It is suggested
that this be done when the coolant is changed.
Close the shut-off valves in the inlet and drain lines before
disassembling the filter. Some engines may have a push-
button valve on the rear of the water pump housing that must
be closed (pushed in) when changing the water filter.
DCA4 Filter Change Interval
6 months or 500 hours
• Change coolant filter (replace with Coolant Filter
DCA4 Corrosion Resistor Cartridge, GROVE
Service Part Number 9414101675).
• Check SCA Levels (use only the DCA4 Coolant Test
Kit, GROVE Service Part Number 9414101675, to
check the coolant additive concentration in the
cooling system).
If SCA levels are less than 1.2 Units/Gal, add Cummins
DCA4 to maintain desired level.
NOTE: Inadequate concentration of the coolant additives
can result in major corrosive damage to the cooling
system components. Over-concentration can
cause formation of a “gel” that can cause
restriction, plugging of coolant passages, and
overheating.
1 year or 1000 hours
• Change coolant filter (replace with Coolant Filter/
DCA4 Corrosion Resistor Cartridge, GROVE
Service Part Number 9414101675).
• Test coolant for contamination.
Condemning limits are:
• Sulfate level greater than or equal to 1500 ppm.
• Chloride level greater than or equal to 200 ppm.
• The pH level is less than 6.5.
• Oil or fuel contamination can be identified by odor or
color.
If condemned, flush the system using a commercially
available flushing agent. Refill system with fully formulated
extended life coolant. Refer to Lubrication, page 9-1.
NOTE: Remove the radiator cap when draining the system
to ensure proper draining.
Cleaning
1. Coolant shut-off valves to heaters and other accessories
should be open to allow complete circulation during
cleaning, flushing, and draining. Run the engine with
radiator covered if necessary until temperature is up to
operating range 71 to 82°C (160 to 180°F). Stop the
engine, remove the radiator cap, and drain the system
by opening the drain cocks on the radiator and engine
block.
NOTE: Use a cleaning compound that is not corrosive to
aluminum to prevent damage to the radiator.
2. Allow the engine to cool, close the drain cocks, and pour
the cleaning compound into the surge tank according to
the directions. Fill the system with water.
CAUTION
The cooling system is pressurized and injury can result
when removing the radiator cap at operating temperature.
Use proper protection to remove the radiator cap.
