Product Description

The Mishimoto MMHOSE-WK2-11BK is a direct-fit silicone radiator hose kit engineered for the 2011-2021 Jeep Grand Cherokee WK2 equipped with the 5.7L HEMI V8. Factory rubber radiator hoses deteriorate over time from heat cycling and pressure, becoming brittle, swollen, or prone to leaking - a failure that can quickly lead to engine overheating and serious damage. Mishimoto's 4-ply silicone hoses with heat-resistant embedded fibers are rated to 330°F and resist the degradation that affects rubber hoses over years of service, making them a reliable long-term upgrade for any Grand Cherokee on the road or trail.

These hoses are designed as a direct OEM replacement, retaining the factory hose routing for a simple bolt-on installation with no cutting or modification required. Worm-gear clamps are included for each connection. Compatible with both stock and Mishimoto performance radiators, and ideal for daily drivers, towing applications, and modified builds alike. Available in black, blue, and red. Backed by Mishimoto's Lifetime Warranty.
