Many heavy-duty vehicles manufactured in 2007 or later have advanced emissions systems that run hotter under the hood than previous models, requiring the use of a silicone coolant hose to maintain optimal temperatures. The Gates Silicone Coolant Hose is a high-quality 4-ply silicone hose that was built to excel when the going gets hot.

Gates® engineers our automotive aftermarket parts in partnership with the top OEMs around the world, so you can trust premium-grade automotive and light truck parts that are built to last.
When heavy-duty and fleet vehicles began implementing Advanced Emissions Systems into their engines, the under-hood temperatures rose to a point where existing coolant hoses couldn’t handle such temperatures. Gates® developed the Sever Service Silicone Coolant Hose to go in and keep working in temperatures up to +260°C (+500°F).
