Gates HVAC Heater Hose P/N:24330
Route coolant to the heater core with the Gates heater hose 51394, a Premium Modular Coolant Hose that installs as a direct-fit replacement on the 2013-2019 Cadillac ATS (see the Buyer's Guide tab for engine-level applications). Cataloged for the heater-to-pipe, heater-inlet position, it's manufactured to fit the specific application and is similar to OEM specifications, integrating the essential OE components — hose branches, quick-connectors, sensors, restrictors and the like — where the original design calls for them.
Modular OE-exact construction: built with OEM-exact hose components (quick connects, branch connectors/tees, sensors) so it fits the factory coolant routing.
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 specs: meets SAE 20R3 EC Class D1 under 25 mm (1 in.) ID and SAE 20R4 EC Class D1 for 25 mm (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.
