ACDelco Professional Molded Engine Coolant Bypass Hose

The ACDelco Professional Molded Engine Coolant Bypass Hose is a replacement coolant bypass hose. It helps carry coolant between engine cooling system components so the engine keeps circulating coolant and holds a steady operating temperature. ACDelco is General Motors' parts brand, and the Professional line is made for dependable repair-shop and DIY installs.

Key Features:

• Molded construction is shaped to follow the routing of the original hose, so it fits correctly without kinking
• Rubber construction is made to handle engine heat, coolant exposure, and pressure
• Designed as a direct replacement for a worn, cracked, swollen, or leaking bypass hose
• Backed by ACDelco's reputation for quality and OE-style fit and function

Replacing an aging coolant bypass hose helps prevent coolant leaks and overheating, and it protects the engine. Replacing the hose clamps and checking the coolant level at the same time is good practice.
