ACDelco 27066x Professional Molded Coolant Hose

The ACDelco 27066X Professional Molded Coolant Hose is a premium aftermarket replacement hose engineered to deliver reliable, long-lasting performance in your vehicle's cooling system. Constructed from specially blended reinforced rubber materials, this hose is built to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure.

Key Features:

• Specially blended rubber construction resists electrochemical degradation (ECD) for extended service life
• Heat and ozone resistant outer cover helps protect against under-hood conditions
• Re-engineered materials resist vacuum collapse, reducing the need for internal springs in many applications
• Factory-molded GM OE-style design fits today's tighter, more compact engine compartments
• Protective sleeve (where applicable) helps duplicate GM Original Equipment designs for proper fit and function
• Installs without buckling, bending out of shape, or straining at the connection
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Approved for marine applications
• Not intended for fuel or oil transfer applications
