UNSPSC 25174000: Engine coolant system

UNSPSC 25174000 Engine coolant system, a Class code, covers the supply and delivery of antifreeze, coolant fluids, and related consumables that state and local governments procure to maintain fleet vehicles, heavy equipment, and facility HVAC systems. Recent solicitations show demand for bulk coolant delivery on standing contracts, individual replacement parts for vehicle fleet operations, and specialized coolant meeting equipment-specific certifications such as Cummins diesel engine standards. Issuing bodies include county transportation and fleet services departments, municipal water authorities, school districts, and regional cooperative purchasing vehicles. County fleet operations and water utilities emerge as the most active segments, particularly in Florida and California, where fleet maintenance and emergency preparedness drive recurring procurement.

Sacramento County's February 2026 RFB for bulk red antifreeze/coolant (ES Compleat OAT meeting Cummins certifications) exemplifies the standing-order model—annual spend approximately $30,000, delivery to a 500-gallon tank within two business days, firm fixed pricing for 12 months with up to four one-year renewals. Collier County's June 2026 ITB for bypass pump preventative maintenance and replacement services (grant-funded, approximately 30+ stations) illustrates the broader engine-cooling-system infrastructure category, with three-year contract terms and $45,000 baseline spend inflated to $14 million post-Hurricane Ian recovery. Macon Water Authority's April 2026 IFB for a replacement bypass pump (Atlas Copco 6-inch unit with solar charger) and Rockwood School District's March 2026 RFB for bus and fleet vehicle parts (covering Cummins diesel and Ford engines) round out the geographic and sectoral spread. Sacramento County's SCOPA cooperative structure, Collier County's federal FEMA compliance and grant funding, and local-preference provisions (Sacramento's 5% local-business incentive) shape procurement terms. The code shows consistent activity across California, Florida, Georgia, Missouri, Connecticut, and New Jersey, with no standout single buyer but sustained demand from mid-to-large county fleets and utility operations managing aging equipment and post-disaster recovery needs.
