The Dayco flex radiator hose replaces straight or molded radiator hoses on a wide range of engine applications. Precision molded in standard lengths, it features a knitted reinforcement and synthetic EPDM construction. This hose is designed to prevent splitting, ballooning and elongation as well as resist ozone and other detrimental environmental elements, coolants and temperature variations of -40°F (-40°C) to +257°F (+125°C). With corrugations that provide excellent hose flexibility without flattening or collapsing, the Dayco flex radiator hose also features a helical steel coil spring for increased flexibility.

 Cooling System Maintenance | Tips & Tools Without regular maintenance, cooling system components will degrade and fail prematurely, which can lead to costly engine damage. Protect your engine with simple preventative maintenance:
- Completely drain and flush the system using Cooling System Flush prior to installation. Flushing the system is critical to prevent system contamination and failure.
- Consider replacing the Thermostat and Radiator Cap as part of routine preventative maintenance. System contamination can cause these parts to degrade and fail over time, which can lead to severe engine damage from overheating.
- Refill radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
