Gates 51860 Premium Modular Coolant Hose

The Gates 51860 Premium Modular Coolant Hose is a factory-molded lower radiator hose engineered to meet OEM quality specifications. This modular assembly hose is designed to fit specific applications and includes integrated OE components such as hose branches, quick-connectors, sensors, and restrictors where applicable.

Key Features:

• Constructed with EPDM tube and cover with synthetic fiber knit reinforcement for superior durability
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Heat and ozone resistant cover maintains integrity in harsh engine environments
• Re-engineered materials resist vacuum collapse, eliminating the need for internal springs in many applications
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 EC Class D1 and SAE 20R4 EC Class D1 standards

Gates modular coolant hoses are precision-manufactured to provide OEM-equivalent fit and performance, offering a reliable aftermarket replacement that saves time and money compared to dealer parts. The advanced EPDM compound resists the electrochemical degradation that occurs when coolant, hose, and metal fittings create a galvanic reaction, ensuring extended service life and reliable cooling system performance.
