Installation Notes

Verify the hose routing, end diameters, and connection points before installation. This Dayco 87610 hose is specified for small I.D. heater applications, so matching the valve-to-thermostat, heater-to-water-pump, heater-to-pipe, or valve-to-water-pump layout is important for proper fit. Inspect adjoining clamps, fittings, and coolant passages for wear or corrosion before service.

Quality Assurance

Dayco specifies this hose to SAE J20R3 Class D-1 and SAE J1684 Type EC standards, supporting consistent heater hose performance in the listed applications. The EPDM construction is selected for coolant-system service in automotive HVAC routing.
