ACDelco Molded Coolant Bypass Hose

The ACDelco Molded Coolant Bypass Hose is a pre-formed engine coolant bypass hose. It carries coolant between engine components so the cooling system can circulate coolant and keep engine temperature steady. It is also called a bypass coolant hose or engine coolant bypass line.

Key Features:

• Molded construction holds a pre-formed shape for a consistent fit and routing
• Made from coolant-resistant rubber designed to handle engine heat, pressure and vibration
• Replaces a worn, cracked, swollen or leaking bypass hose
• Backed by ACDelco, a brand with a long history as a General Motors parts supplier

Replacing an aging bypass hose helps prevent coolant leaks and overheating. Check the clamps and fittings during installation, and refill the cooling system with the correct coolant.
