Cummins Inc. recommends the use of fully-formulated antifreeze or coolant containing a precharge of supplemental coolant additive (SCA). The antifreeze or coolant
must meet the specifications outlined in the Technology and Maintenance Council (TMC) Recommended Practice (RP) 329 (ethylene glycol) or Recommended Practice (RP) 330 (propylene glycol). The use of fully-formulated antifreeze or coolant significantly simplifies cooling system maintenance.
Copies of Technology and Maintenance Council (TMC) specifications can be obtained through Cummins Inc., or by contacting:
- Technology and Maintenance Council
- American Trucking Association
- 2200 Mill Road
- Alexandria, VA 33314-5388
- Phone: (703) 838-1763
- Fax (703) 836-6070
Fully-formulated antifreeze contains balanced amounts of antifreeze, SCA, and buffering compounds, but does
not contain 50 percent water. Fully-formulated coolant contains balanced amounts of antifreeze, SCA, and buffering compounds already premixed 50/50 with deionized water.
Alternative maintenance practices for cooling systems can be found in Cummins® Coolant Requirements and Maintenance, Bulletin 3666132.
