Description
The 2018+ Jeep Wrangler JL 2.0L runs one of the most complex cooling setups Mishimoto has developed for, with separate circuits feeding the engine, the battery system, and the charge air cooler. The Mishimoto Silicone Coolant Hose Kit (MMHOSE-JLH-18BK) is built specifically to replace the factory rubber and plastic primary radiator hoses on this 2.0L engine, using a four-layer silicone and heat-resistant fiber construction paired with a one-piece lower hose that eliminates the factory plastic connector entirely.
Keeping coolant in its proper circuit matters on a multi-system layout like the JL 2.0L, and this Mishimoto cooling upgrade is engineered to do exactly that. In place of the factory’s plastic hose barb and mounting hardware, Mishimoto machines the barb and mounting plate from aluminum, giving the lower hose assembly far fewer points of potential failure than the stock rubber-and-plastic setup. The kit is a specific-fit, performance-grade replacement rather than a universal hose, so it installs using the factory mounting locations, and Mishimoto backs the whole hose kit with its Lifetime Warranty.
