Rubber radiator hoses are prone to dry rot, cracking, and leaking, and nobody wants to find a coolant puddle under their truck. Get ahead of the game for your 2019+ Chevrolet Silverado or GMC Sierra 5.3L or 6.2L and upgrade your factory radiator hoses to durable, high performance silicone hoses. The Mishimoto Silicone Radiator Hose Kit is a direct fit replacement and includes the upper and lower radiator hoses and all three coolant overflow hoses. Unlike the degradation-prone factory rubber hoses on your 5.3L or 6.2L, Mishimoto silicone radiator hoses are constructed from five layers of silicone with heat-resistant embedded fibers, providing unrivaled durability, heat resistance, and pressure tolerance. Available in black, blue, and red, not only is this a great upgrade that provides you with long-lasting durability, but you can also add a pop of color and style to your engine bay! Like all our parts, the Mishimoto Silicone Radiator Hose Kit, Chevrolet/GMC 1500 5.3L/6.2L 2019+ is backed by our Mishimoto Lifetime Warranty.
