Detailed Description

Dayco 87316 is a small I.D. heater hose intended for heater circuit and coolant transfer paths that require a 1/2 in. hose connection. The EPDM rubber construction is suited to underhood temperature exposure, while the single I.D. design supports straightforward routing in compact engine bays. This part number is a practical choice for vehicles that use a small-diameter hose between the heater circuit, intake manifold, thermostat housing, or pipe connections.

What It Helps Address

• Cracked or hardened heater hose material
• Coolant seepage at small-diameter hose connections
• Restricted heater flow from deteriorated hose routing
• Incorrect hose size at 1/2 in. heater hose connections
• Replacement needs for heater-to-pipe and manifold-to-thermostat routing

Installation Notes and Tips

Verify the hose path, end diameters, and routing before installation. Match the 1/2 in. inside diameter to the vehicle connection points and confirm whether the application uses heater-to-pipe, pipe-to-intake-manifold, or intake-manifold-to-thermostat routing. Inspect adjoining clamps, pipes, and fittings for wear or corrosion before installing Dayco 87316.
