Gates 52108 Molded Coolant Hose 1-11/16" x 2" x 21-1/4"

The Gates 52108 is a factory-molded coolant hose engineered to OEM-quality specifications. Precision-shaped for a leak-free fit, this radiator hose is a direct replacement for upper, lower, bypass, heater, and other coolant circuit applications — eliminating the need for a costly trip to the OE dealership.

Gates molded coolant hoses are built to combat Electrochemical Degradation (ECD) — the leading cause of hose failure. ECD occurs when the hose, liquid coolant, and engine or radiator fittings form a galvanic cell, triggering a chemical reaction that creates micro-cracks in the hose tube. Left unchecked, coolant seeps into these cracks, breaks down the reinforcement layer, and leads to hose failure and unexpected breakdowns.

Key Features:

• Factory-molded construction for precise OEM-fit replacement
• Engineered to resist Electrochemical Degradation (ECD)
• EPDM tube construction with synthetic fiber knit reinforcement and EPDM cover
• Heat and ozone-resistant outer cover
• Re-engineered materials resist vacuum collapse
• Approved for marine applications
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 standards
• Dimensions: 1-11/16" x 2" x 21-1/4"

Note: Gates recommends replacing hose clamps each time a new coolant hose is installed. Not intended for fuel or oil transfer applications.
