Detailed Description

Dayco 87716 is an HVAC heater hose intended for small inside diameter applications where a 5/8 in. hose is required. The EPDM material is commonly used in coolant and heater hose service because it handles heat and fluid exposure in underhood environments. This hose is listed for multiple positions, including pipe to engine, engine to pipe, valve to engine, heater to valve, pipe to valve, heater to pipe, and pipe to auxiliary heater valve applications.

This part cross-references Gates 18908 for the same application. For buyers searching by vehicle, Dayco 87716 is a relevant replacement for Chevrolet Camaro heater hose service, Pontiac Firebird heater hose routing, and Chevrolet Express or GMC Savana heater hose connections in the listed configurations.

What It Helps Fix

• Cracked or hardened heater hose rubber
• Coolant seepage at heater hose connections
• Restricted heater flow from deteriorated hose sections
• Incorrect hose diameter during heater hose replacement
• Service issues on pipe-to-engine or valve-to-engine heater lines

Installation Notes and Tips

Verify the required 5/8 in. inside diameter and match the vehicle position exactly before installation. Confirm whether the application is pipe to engine, engine to pipe, valve to engine, heater to valve, pipe to valve, heater to pipe, or pipe to auxiliary heater valve. This hose does not include a heat shield or protective sleeve, so inspect nearby routing and clamp areas before reuse. Drain coolant as needed and replace any hose that shows swelling, cracking, or soft spots.

Quality Assurance

Built to SAE J20R3 Class D-1 and SAE J1684 Type EC specifications, Dayco 87716 is made for heater hose service in the listed Chevrolet and GMC applications. The EPDM construction supports consistent performance in coolant transfer use.
