Gates 65002 Premium Molded Coolant Hose

The Gates 65002 is a premium factory-molded thermoplastic coolant hose engineered to deliver OEM-quality performance in cooling system applications. Precision-shaped to fit specific applications, this hose is a direct replacement for upper, lower, bypass, and heater coolant positions, eliminating the need for a costly OE dealer visit.

Gates molded coolant hoses are constructed with an EPDM tube, synthetic fiber knit reinforcement, and a heat- and ozone-resistant EPDM cover. The materials are specifically engineered to combat electrochemical degradation (ECD) — the leading cause of coolant hose failure. ECD occurs when the hose, liquid coolant, and metal fittings interact to form a galvanic cell, generating micro-cracks that allow coolant to seep into the reinforcement layer and ultimately cause hose failure.

Key Features:

• Factory-molded for a precise OEM-quality fit and perfectly sealed connections
• EPDM construction resists heat, ozone, and chemical coolants
• Engineered to resist electrochemical degradation (ECD) — the leading cause of hose failure
• Synthetic fiber knit reinforcement resists vacuum collapse, reducing the need for internal springs
• Meets SAE 20R4 EC Class D1 requirements
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Approved for marine applications
• Not intended for fuel or oil transfer applications

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a secure, leak-free seal.
