Product Details

This Continental molded radiator coolant hose is engineered for upper cooling-system routing on a wide range of Chevrolet and GMC trucks, vans, and utility vehicles. The EPDM construction and synthetic reinforcement are specified to handle coolant transfer in demanding engine bay conditions, while the molded shape supports the original hose path used on the vehicle. Continental 61099 is a direct-fit style replacement for applications such as Chevrolet C1500, Chevrolet K2500, GMC K1500 Suburban, and GMC P3500, with fitment varying by radiator size and equipment package.

This part cross-references Gates 21191 and Dayco 71036 for the same application.

What It Helps Address

• Coolant leaks from a cracked or aged upper radiator hose
• Softening, swelling, or collapse of the hose under heat
• Improper hose routing after a previous replacement
• Loss of coolant circulation through the upper cooling circuit
• Fitment issues on molded OE-style Chevrolet and GMC cooling systems

Installation Notes and Tips

• Verify radiator size, engine bay configuration, and notes such as w/o AC, exc. Cab & Chassis, or 41" radiator before ordering.
• Some applications are listed as cut-to-fit; confirm the vehicle-specific routing before trimming.
• Inspect hose clamps, thermostat housing, and radiator necks for wear before installation.
• After installation, refill the cooling system with the correct glycol-based coolant and check for leaks at operating temperature.

Quality Assurance

Continental 61099 is built to meet or exceed SAE 20R4EC Class D1 requirements and uses EPDM materials with synthetic reinforcement for cooling-system service. The molded OEM configuration supports accurate fitment on listed Chevrolet and GMC upper radiator hose applications, including Chevrolet P30, GMC G3500, and related models.
