Gates 06-07 Subaru B9 Tribeca 6-Cyl. 3.0L Lower Molded Coolant Hose

The rubber compound in this Gates lower radiator hose is formulated to withstand the heat and pressure found in your 2006-2007 Subaru B9 Tribeca's 3.0L 6-cylinder engine. This molded hose is shaped specifically to fit the routing from the radiator to the engine block, ensuring a clean installation and preventing kinks that could restrict coolant flow.

Gates uses a heat-resistant EPDM rubber for the inner tube and cover, which is reinforced with synthetic fiber braiding. This construction helps the hose maintain its shape and resist degradation from coolant chemicals and engine bay temperatures. Because it's a molded hose, it replaces the factory original part directly, meaning you won't have to fight with a hose that doesn't quite bend the right way or requires excessive stretching.

When replacing your coolant hoses, it's a good idea to check the condition of the upper hose and thermostat housing as well. Having all the coolant system components in good shape helps prevent overheating and keeps your engine running smoothly.
