Dayco Expands Radiator Hose Availability

Dayco’s addition of 283 radiator hose part numbers helps aftermarket distributors capture growing cooling maintenance demand on high-stress turbocharged vehicle fleets.

Engine components supplier Dayco North America has launched an aggressive inventory expansion plan featuring 283 new radiator hose part numbers designed for complex vehicle applications. The phased rollout schedules 66 SKUs for immediate November availability and another 40 before year-end, with the final batch arriving by the close of the first quarter of 2027. The project elevates Dayco’s total vehicles-in-operation (VIO) market coverage to 90%, representing a 20% jump over 2025 levels.

For Canadian automotive jobbers, commercial warehouse distributors, and mechanical repair shop owners, having prompt local access to branched and simple cooling hoses eliminates parts procurement delays and bay downtime. The surge in aftermarket replacement opportunities is largely driven by aging vehicle fleets and the intense operational heat loads generated by modern downsized, turbocharged powertrains on underhood rubber circuits.

Engineered to exact OEM form, fit, and function criteria, the hose lines incorporate heavy-duty EPDM rubber compounds built to resist electrochemical degradation and high-pressure fluid leaks. According to Dayco product management, expanding catalogued part numbers enables independent aftermarket repair channels to secure immediate repair order revenue on late-model cooling system service intervals typically retained by dealership service lanes.
