Gates 24451 Premium Modular Coolant Hose Lower Radiator Hose

The Gates 24451 Premium Modular Coolant Hose is a factory-molded lower radiator hose engineered to deliver OEM-quality performance for demanding cooling system applications. This modular coolant hose features integrated components including hose branches, quick-connect fittings, and precision-molded construction to match original equipment specifications.

Key Features:

• Constructed from premium EPDM rubber with synthetic fiber knit reinforcement for superior durability
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Molded design with 2 branches and 1 quick-connect fitting for proper fit and sealed connections
• 24.25-inch centerline length with multiple connection points: 1-1/2", 1-11/16", and two 3/4" inside diameter ends
• Temperature range: -40°F to +257°F (-40°C to +125°C) for reliable performance in extreme conditions
• Meets SAE 20R3 EC Class D1 (under 1" ID) and SAE 20R4 EC Class D1 (1" ID and over) specifications
• Approved for marine applications with resistance to heat, ozone, and chemical coolants
• Specifically-engineered materials resist vacuum collapse, eliminating need for internal springs

Gates modular coolant hoses are manufactured to exact specifications similar to OEM designs, incorporating essential integrated components for proper cooling system function. The advanced EPDM compound provides superior resistance to electrochemical degradation that occurs when coolant, hose material, and metal fittings create a galvanic reaction. This protection extends service life and prevents the micro-cracking that leads to coolant leaks and engine overheating. Suitable for coolant, water, and air applications. Note: Gates recommends replacing hose clamps each time a new coolant hose is installed.
