Coolant Filter
General Information
Change the coolant filter at every oil and filter change interval unless the supplemental coolant additive (SCA) level is over 3 units. See Supplemental Coolant Additive-Maintenance check in this section. The SCA level must be tested every six months. The correct coolant filter to be used is determined by the total cooling system capacity and other operational factors. For the correct filter selection, Refer to Coolant Recommendations and Specifications in Maintenance, Procedure 018-004, in Section V.

Maintenance Check
Supplemental Coolant Additive (SCA) Check the SCA concentration level: • At least twice a year • At every subsequent oil drain interval if the concentration is above 3 units • Whenever coolant is added to the cooling system between filter changes. Use Fleetguard® coolant test kit, Part No. CC2602, to check the SCA concentration level. Instructions are included with the test kit. Refer to Coolant Recommendations and Specifications in Maintenance Specifications (Section V) for the correct SCA and antifreeze level. Antifreeze
Check the antifreeze concentration. Use a mixture of 50- percent water and 50% ethylene glycol or propylene glycol-based antifreeze to protect the engine to -32°C (-26°F) year-around. The Fleetguard® refractometer, Part Number C2800, provides a reliable, easy-to-read, and accurate measurement of freezing point protection and glycol (antifreeze) concentration. Antifreeze is essential in every climate.
CAUTION!
Over concentration of antifreeze or use of high-silicate antifreeze can damage the engine. Figure 102
Figure 103
QSM11 Cummins Engine QSM11CUMMINSENG Page 71
Antifreeze broadens the operating temperature range by lowering the coolant freezing point and by raising its boiling point. The corrosion inhibitors also protect the cooling system components from corrosion and prolong component life.
