Detailed Product Description

The Gates Molded Coolant Hose 52043 is engineered to meet the specific cooling system requirements of Nissan Altima models. Its EPDM construction offers excellent resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The hose features a consistent inside diameter of 1.31 inches (33 mm) on both ends, facilitating proper coolant circulation without restrictions. With a centerline length of 19.5 inches (495 mm), this molded hose fits precisely within the cooling system layout, reducing the risk of leaks or improper connections. The absence of internal springs allows for a smooth coolant flow path, minimizing turbulence and potential wear points.

About the Molded Coolant Hose Product Line

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns. Verify that the hose dimensions match the original part, specifically the 1.31-inch inside diameter and 19.5-inch centerline length. Use appropriate clamps to secure the hose ends firmly without over-tightening, which could damage the EPDM material. Inspect surrounding components for wear or damage during installation to maintain overall cooling system integrity.
