There's no worse feeling than walking out to your truck and seeing a puddle of coolant under it. As vehicles grow older, the rubber components under the hood start to degrade. It's only a matter of time before the radiator hoses begin to leak.The best time to replace a leaking hose is before it starts leaking. That's why Mishimoto has created a silicone radiator hose kit for your 2015-2017 Ford Expedition 3.5L EcoBoost. Built with five layers of durable silicone embedded with heat-resistant fibers, these hoses will withstand the test of time. These Mishimoto silicone hoses include a pre-installed quick disconnect on the lower hose to make installation easy. We've also replaced the leak-prone plastic connector with durable stainless steel for long-lasting reliability and leak-free operationThis kit includes both the upper and lower radiator hoses and is available in black, blue, or red. Plus, all our products are backed by our Lifetime Warranty, so you'll never have to see another coolant puddle again.
