Gates 23704 Lower Radiator Coolant Hose

The Gates 23704 is a premium molded lower radiator coolant hose engineered to OEM-quality specifications for reliable cooling system performance. This pre-shaped hose is designed to ensure a perfect fit and sealed connection in your vehicle's cooling system.

Key Features:

• EPDM (ethylene propylene diene monomer) rubber construction for superior durability
• Molded design with 1.31-inch inside diameter at both ends
• 17.6-inch centerline length for precise fitment
• Engineered to resist electrochemical degradation, the leading cause of coolant hose failure
• Aramid or rayon knit reinforcement for strength and flexibility
• Resistant to heat, ozone, and chemical coolants
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 requirements
• Marine application approved

Gates molded coolant hoses feature specifically-engineered materials that resist vacuum collapse, eliminating the need for internal springs in most applications. The EPDM compound provides superior resistance to electrochemical degradation (ECD), which occurs when the hose, coolant, and metal fittings create a galvanic reaction that can cause premature hose failure. This advanced engineering ensures longer service life and reliable engine cooling performance.
