Detailed Product Description

The Gates Molded Coolant Hose 22275 is a radiator coolant hose engineered to meet the specific requirements of certain Nissan and INFINITI vehicles. Its construction from EPDM rubber and plastic provides resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The hose features two different inside diameters—1.34 inches (34 mm) on one end and 1.55 inches (39 mm) on the other—allowing it to connect seamlessly between components with varying sizes. With a centerline length of 18.2 inches (462 mm), this molded hose fits precisely without the need for modification. The absence of springs and quick connect fittings simplifies the design and reduces potential failure points.

Common Applications and Issues Addressed

• Replacement of worn or cracked radiator coolant hoses in Nissan Pathfinder and INFINITI QX4
• Resolving coolant leaks caused by hose degradation
