The third generation 4Runner provides impressive versatility, combining superb off-road capability with a spacious and comfortable interior. Whether you’re crawling down an off-road trail or commuting to work, cooling system reliability is key to ensuring the long lifespan of your 3.4L. However, with your 4Runner navigating thousands of miles for over 20 years, chances are the stock heater hoses are beginning to show some wear. Mishimoto has you covered with our new silicone heater hose kit explicitly developed for the 1996-2002 Toyota 4Runner 3.4L. Mishimoto silicone hose kits are constructed from 4-ply silicone with heat-resistant embedded fibers to provide optimal heat and pressure tolerance. Our kit includes hoses for both the front and rear heater core connections and a complete set of high-quality worm-gear clamps for easy installation. This kit is offered in black, blue, or red silicone for those seeking to add stylish accents to their engine compartment. As with all our products, this Toyota 4Runnder Silicone Hose Kit includes our signature Lifetime Warranty.
