Gates 65001 Molded Coolant Heater Hose

The Gates 65001 is a molded EPDM heater hose designed to provide reliable coolant circulation in automotive cooling systems. This pre-formed hose is engineered to resist electrochemical degradation (ECD), the leading cause of heater hose failure that occurs when the hose, coolant, and metal fittings form a galvanic reaction.

Key Features:

• EPDM construction resists electrochemical degradation for extended service life
• Pre-molded design ensures proper fit and eliminates kinking
• Resistant to most coolants and non-oil based coolant additives
• Withstands high cooling system pressures without deterioration
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Resists water permeation to prevent coolant loss

Gates molded heater hoses are designed for OE-quality replacement on cars, light trucks, and other automotive applications. This molded configuration provides a direct-fit solution that simplifies installation and ensures reliable performance. Not for use with fuel or oil transfer applications.
