There's no worse feeling than walking out to your Ford F150 3.5L Ecoboost 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 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 2011, 2012, 2013, or 2014 Ford F-150 3.5L EcoBoost. Built with five layers of durable silicone embedded with heat-resistant fibers, these hoses will withstand the test of time. These hoses also replace the leak-prone plastic connectors with durable stainless steel for long-lasting reliability and leak-free operation. This kit includes both the upper and lower radiator hoses and is available in black, blue, or red. Plus, all of Mishimoto's products are backed by their Lifetime Warranty, so you'll never have to see another coolant puddle again.
