Keeping it Cool.

Effective and dependable coolant hose performance is critical to keeping your engines at optimal operating temperature. If your coolant hose unexpectedly fails, the leakage can cause significant, expensive damage to your engine system. That's why we've engineered our engine coolant hoses with silicone and spiral reinforcement for high temperature, corrosion, and wear resistance, so you can keep your engines running with the confidence of a strong, consistent, and reliable cooling system.

Inspecting Your Coolant Hose.

As part of our Be System Part initiative, we recommend regularly inspecting your critical vehicle systems, including your cooling system and hoses, at around 60,000 miles. As your coolant hose begins to age, the constant transfer of chemical fluids will corrode your hose from the inside out. When inspecting your coolant hose, there are a few simple signs that it's ready for replacement:

Press for Soft Spots. The radiator hose is naturally rigid, and any soft spots along the hose body indicates the inner material has begun to break down. Firmly press on the hose body to feel for potential deteriorations.

Check the Ends and Fittings. Look for cracks around the hose end, especially near the hose clamps.

Feel for Bulges. Run your hands along the hose body to feel for protruding materials, which indicate a rupture within the hose that will eventually lead to failure.
