ACDelco 20694S Professional Molded Coolant Bypass Hose

The ACDelco 20694S Professional Molded Coolant Bypass Hose is a premium aftermarket replacement hose engineered to restore proper coolant flow in your vehicle's cooling system.

• Constructed from a proprietary blend of EPDM synthetic rubber for superior pliability and long service life
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Temperature rated from -40°F to 275°F (-40°C to 135°C) for reliable performance across all climates
• Suitable for coolant and water applications
• Manufactured to meet or exceed OE specifications for fit, form, and function

The ACDelco Professional line — also marketed as ACDelco Gold — represents a high-quality alternative to original equipment parts, backed by General Motors and designed to deliver the performance and dependability expected from the ACDelco name.
