Heater Hose

Designed to carry the heated coolant from the engine block to the heater core under the dashboard and return it to the engine.

Dayco’s standard heater hose is made for general service on light trucks and passenger cars. Constructed using all EPDM compounds and spiral reinforcement for high burst strength and an excellent heat resistance of -40°F (-40°C) to +257°F (+125°C). This black cover hose is similar to SAE 20R3, Class D-2, and is specifically designed to be compatible with all common coolants and coolant additives.

NOT suitable for fuel or oil transfer.
