Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids.

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns. Verify the hose dimensions match the original part, focusing on the 1.32-inch inside diameter and 21.8-inch 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.
