Product Details
This Dayco Small I.D. Heater Hose is intended for coolant transfer between the engine and heater core on vehicles that use a 5/8 in. hose connection. The EPDM material is commonly used in heater hose applications because it is suited to hot coolant service, while the single I.D. hose layout supports the engine-to-heater routing found on the listed Nissan models. Dayco 87752 is a practical replacement choice when servicing the heater hose on a 1995-1997 Nissan Pickup or a 1990-1994 Nissan D21.
Compatible With 1995-1997 Nissan Pickup, engine to heater, and 1990-1994 Nissan D21, engine to heater. This part cross-references Gates 18863 and NAPA 10863 for the same application.
Common Uses
- Replacing a cracked or heat-aged heater hose
- Restoring coolant flow from the engine to the heater core
- Addressing coolant seepage at a 5/8 in. hose connection
- Correcting soft, swollen, or deteriorated rubber hose sections
- Servicing heater hose routing on Nissan Pickup and Nissan D21 models
Installation Notes
Verify the hose routing, inside diameter, and connection points before installation. Match the engine-to-heater path exactly and inspect adjoining clamps, fittings, and heater core nipples for wear or corrosion before reassembly. Confirm that the hose is routed without kinks or contact with hot or moving components.
Quality Assurance
Dayco manufactures this heater hose to SAE J20R3 Class D-1 and SAE J1684 Type EC specifications, supporting consistent material and performance requirements for heater hose service.
