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
Manufactured with OEM-exact hose components (quick connects, branch connectors/tees, sensors, etc.)
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

MacKay utilizes leading edge rubber technology and compounds, supported by in-house processes from rubber mixing to final product. This ensures hoses are made to the strict specifications required for the advanced motor vehicles of the 21st century. In vehicles of today, a hose has to be designed to withstand the stresses of modern, more compact but powerful engines that run hotter and at a higher pressure. Other factors include smaller engine compartments with poor heat dissipation, aggressive coolant additives, and stray (electrochemical) current that may be conducting through the cooling system. In short, the smaller but more powerful engines of today work a lot harder than the larger engines that were standard before. More heat is generated, higher burst pressures are required in cooling system components, and hoses have to be made tougher to withstand these demands. MacKay’s research and development chemists have developed new rubber formulations and manufacturing processes that ensure MacKay hoses meet the greater wear and heat demands created by modern engines. Rubber compounds used in automotive hoses today are predominantly synthetic rubber formulation. All MacKay coolant hoses are made from EPDM compounds that are highly resistant to ozone attack. Hoses made from some other rubber compounds may be subject to ozone deterioration.

Product Features:

Excellent resistance to high temperatures
Resists chemical attack (oils, fuels etc.)
Excellent Ozone resistance
Good resistance to abrasion
High resistance to vibration
