Fill
Close the radiator draincocks.
Install the lower radiator hose(s).
Tighten the hose clamps.
Torque Value: 5 n.m [44 in-lb]
Close the engine draincock.
Close the oil cooler draincock or plug.
Cummins Inc. recommends using
either a 50/50 mixture of good quality
water and fully formulated antifreeze,
or fully formulated coolant when filling
the cooling system. The fully
formulated antifreeze or coolant must
meet TMC RP 329 or TMC RP 330
specifications.
Good quality water is important for
cooling system performance.
Excessive levels of calcium and
magnesium contribute to scaling
problems, and excessive levels of
chlorides and sulfates cause cooling
system corrosion.
Cummins Inc. recommends using
Fleetguard® Compleat™. It is
available in both glycol forms
(ethelyne and propylene) and
complies with TMC standards.
NOTE:
NOTE: Some radiators have two fill
locations, both of which must be filled
when the cooling system is drained.
Fill the cooling system with coolant to
the bottom of the fill neck in the
radiator fill (or expansion) tank.
Install the radiator or expansion
tank fill cap.
Operate the engine until it reaches
a temperature of 82°C [180°F],
and check for leaks.
WARNING
Do not remove the pressure cap
from a hot engine. Wait until the
coolant temperature is below 50°C
[120°F] before removing the
pressure cap. Heated coolant spray
or steam can cause personal injury.
Shut the engine OFF and allow it to
cool.
CAUTION
Do not add cold coolant to a hot
engine. This can cause engine
casting damage. Allow the
engine to cool to below 50°C
[120°F] before adding coolant.
Remove the radiator or fill cap, and
check the coolant level per the
OEM service manual
recommendations. Add coolant if
necessary. Do not over fill.
