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.

Product Features:

• Specifically-engineered materials resist collapse under vacuum
• Engineered to resist electrochemical degradation – the leading cause of hose failure
• EPDM tube; synthetic fiber knit reinforcement, heat, ozone- and chemical coolant-resistant EPDM cover

• Meets SAE 20R3 EC Class D1 under 25mm (1 in.) ID, SAE 20R4 EC Class D1 for 25mm (1 in.) ID and over
• Temperature Range: -40 Deg. F to +257 Deg. F (-40 Deg. C to +125 Deg. C)
• Note: Gates recommends replacing clamps each time a new coolant hose is installed
• Caution: Do not use for fuel or oil transfer applications
