Gates HVAC Heater Hose P/N:51470

Keep coolant moving between the radiator and reservoir with the GATES heater hose 51470, a premium modular coolant hose built as a direct-fit replacement for the 2015-2016 Chevrolet Silverado Series Pickup, Silverado 2500 HD, Silverado 3500 HD, GMC Sierra 2500 HD and GMC Sierra 3500 HD. Gates leads the modular assembly coolant hose segment, building each hose to specific applications with OEM-exact integrated components — quick connectors, branch connectors/tees, sensors and restrictors — so it drops in like the original.

• EPDM construction: EPDM tube, synthetic fiber knit reinforcement, and a heat-, ozone- and chemical coolant-resistant EPDM cover.
• Holds its shape: specifically-engineered materials resist collapse under vacuum.
• Fights the #1 failure mode: engineered to resist electrochemical degradation, a leading cause of hose failure.
• Rated to spec: meets SAE 20R3 EC Class D1 under 25 mm (1 in.) ID and SAE 20R4 EC Class D1 for 25 mm and over, across a temperature range of -40°F to +257°F (-40°C to +125°C).

Gates recommends replacing the clamps each time a new coolant hose is installed. Do not use for fuel or oil transfer applications.
