Whether you're working on a construction site or sending fleets across the country, maintaining the proper engine temperature is critical to ensure your trucks, busses, and vehicular equipment run properly. Our heavy-duty coolant hoses are designed for superior resistance to corrosion, chemicals, and high-operating temperatures, and they're tested to stand up to some of the most challenging applications in the industry.
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 deterioration. 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.
