The Gates 12303 is a precision-molded heater hose designed to replace worn or damaged OEM heater hoses in automotive cooling systems. This hose provides a critical connection between the engine and heater core, ensuring proper coolant flow for effective cabin heating and optimal engine temperature regulation.

Key Features:

• Precision-molded construction ensures exact OEM fit and proper routing
• EPDM rubber compound resists coolant chemicals, heat, and ozone deterioration
• Reinforced construction withstands constant pressure cycling and temperature extremes
• Pre-formed bends eliminate kinking and maintain consistent coolant flow
• Direct replacement for original equipment heater hose

Gates heater hoses are engineered to meet or exceed OEM specifications, providing reliable performance in demanding underhood environments. The molded design ensures proper fitment and eliminates the need for multiple clamps or adapters common with universal hoses.
