Cadillac STS Belts and Hoses

Modular coolant hoses are on many of today’s vehicles and are much more complex than the standard molded hoses of the past. Modular coolant hoses are hose assemblies with one or more components built into the hose. Some examples of these components include hose branches, quick connectors, valves, sensors, bleeders and flow restrictors. Manufactured identical or equivalent to the OE hose, modular coolant hoses will keep your vehicle’s cooling system running properly and efficiently for years to come.
