Gates 26522 Radiator Coolant Hose - Lower or Upper

Heavy-Duty Flexible Coolant Hose

Gates 26522 is a heavy-duty radiator coolant hose built for trucks, buses, and other demanding cooling systems. This Green Stripe Vulco-Flex hose uses a flexible construction with built-in spiral wire to replace a wide range of molded hose shapes while maintaining the performance expected from a permanent coolant hose replacement.

Compatible With heavy-duty cooling system service where a 2.25 in. inside diameter hose and 17 in. centerline length are required. Gates 26522 is also a practical search match for truck radiator hose replacement, bus coolant hose replacement, and flexible molded hose substitute applications.

Product Details

The Gates Green Stripe Vulco-Flex hose line is built for applications where a molded hose shape is difficult to source or where a flexible replacement is preferred. This hose is engineered as a permanent replacement option that matches the performance expectations of molded radiator hoses while giving technicians more installation flexibility in heavy-duty cooling systems. For buyers searching Gates 26522, radiator coolant hose, or heavy-duty flexible coolant hose, this part number identifies a 2.25-inch EPDM and steel hose with a 17-inch centerline length.

This part cross-references Dayco 82191GL and ACI 82191 for the same application.

What It Helps Solve

• Cracked or leaking radiator coolant hose sections
• Hard-to-find molded hose shapes on heavy-duty vehicles
• Cooling system service needs on trucks and buses
• Replacement of aging EPDM hose material
• Fitment challenges where a flexible straight or curved hose is needed

Installation Notes and Tips

Verify the hose inside diameter, centerline length, and routing before installation. Gates 26522 is a non-molded hose, so confirm that the hose path allows proper bend radius and clearance around nearby components. Inspect clamps, necks, and adjoining coolant system parts for wear before reassembly, and refill and bleed the cooling system according to the vehicle service procedure.
