Description

Keep coolant moving to the cabin heater with the Gates heater hose 51749, a premium modular coolant hose built for the heater-outlet-to-tee position on the 2015-2022 Chevrolet Colorado and 2015-2022 GMC Canyon. Gates leads the modular assembly coolant hose segment, building each Gates HVAC heater hose to fit specific applications with specifications similar to OEM — including the essential integrated components such as hose branches, quick-connectors, sensors and restrictors.

Modular OE-exact build: manufactured with OEM-exact hose components (quick connects, branch connectors/tees, sensors, etc.) for a specific-application fit.
EPDM construction: EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover.
Engineered materials: specifically engineered to resist collapse under vacuum and to resist electrochemical degradation, the leading cause of hose failure.
Rated performance: meets SAE 20R3 EC Class D1 under 25mm (1 in.) ID and SAE 20R4 EC Class D1 for 25mm (1 in.) ID and over; temperature range -40°F to +257°F (-40°C to +125°C).

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