Dayco North America has introduced 283 new radiator hose part numbers to address the cooling system needs of an aging vehicle fleet. This expansion boosts the company's total market coverage for vehicles-in-operation to 90%, a 20% increase over 2025 levels.
Why it matters
As vehicle fleets continue to age and engines increasingly rely on turbocharged powertrains, cooling system components are subject to higher heat loads that degrade rubber parts. Maintaining these circuits is critical for preventing engine overheating and costly secondary repairs.
The rollout includes 283 new part numbers, with 66 SKUs arriving in November 2026 and 40 more before the end of the year. The remaining parts are scheduled to be available by the end of Q1 2027.
The players
Dayco North America
An automotive parts manufacturer specializing in engine products, power transmission belts, and heavy-duty cooling system components.
The details
These new hoses utilize heavy-duty EPDM rubber compounds designed to withstand the intense thermal stress generated by modern engine designs. By expanding the available SKU inventory, the manufacturer aims to ensure that older vehicles and newer turbocharged models have access to specialized cooling circuit replacements. Proper fitting of these hoses is essential for maintaining a pressurized cooling system and preventing coolant leaks.
Timeline
November 2026: 66 initial SKUs are released.
End of 2026: 40 additional SKUs become available.
End of Q1 2027: Final delivery of remaining part numbers arrives.
The Home Front
This product expansion tracks with the current national trend of rising average vehicle ages that requires more frequent cooling system maintenance. It marks a shift to support a broader range of older models that have historically been harder to service with original-equipment-spec parts.
If you are experiencing coolant leaks or notice brittle, cracked rubber hoses under your hood, schedule a professional inspection to determine if your cooling system requires service. Keep your vehicle's make, model, and year on hand to confirm parts compatibility with your mechanic.
The takeaway
Maintaining your cooling system with high-grade EPDM rubber hoses is vital for long-term engine health in aging or turbocharged vehicles. Always consult with a licensed mechanic to ensure you are selecting the correct part number for your specific vehicle configuration.
