CHASSIS INFORMATION
Fully formulated antifreeze or coolant containing a precharge of
Supplemental Coolant Additives (SCA) is recommended. The use of either
will significantly simplify coolant system maintenance. The difference
between a fully formatted antifreeze and a fully formatted coolant is the
percentage of water. Both contain balance amounts of antifreeze, SCA,
buffering compounds and a percentage of good clean quality water. The
antifreeze of coolant must meet ethylene glycol or propylene glycol
recommendations. A good clean quality water in a 50/50 ratio
(40 to 60% working range) mixed with fully formatted antifreeze will
provide protection from -34º F to 228º F. The 50/50 mix ratio must be
premixed prior to being put in the system. Placing antifreeze and water in the
cooling system is not recommended. Consult the
Cummins Operation &
Maintenance Manual
for more details.
NOTE: An over concentration of antifreeze, or the use of high
silicate antifreeze, can cause damage to the coolant system and
engine. Antifreeze is essential in every climate.
WARNING: Do not continue engine operation when engine
temperature rises above 220º F. At 220º an engine warning light
will illuminate and the engine will begin to de-rate in power
output. Continued operation will result in engine damage.
The coolant level and fluid freeze point should be checked with every oil
change interval, at 15,000 miles, 500 hours or six months, whichever comes
first. Also change the coolant filter at the same interval unless SCA
concentration is over three units. The coolant should be drained and flushed
at 6,000 hours or two years of service, whichever comes first.
