Restore proper coolant flow through your heating and cooling circuit with the Gates heater hose 51656, a premium modular coolant hose that drops in as a direct-fit replacement for the 2012-2013 Chevrolet Impala and the 2014-2016 Chevrolet Impala Limited. Built with OEM-exact integrated components, this Gates hvac heater hose is engineered to fit its specific applications the way the factory hose did.

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

This hose routes reservoir to connector and reservoir to pipe. Gates recommends replacing the clamps each time a new coolant hose is installed. Do not use for fuel or oil transfer applications. See the Buyer's Guide tab for engine-level fitment details.
