Description
The Mishimoto MMHOSE-JLP-18ABK silicone coolant hose kit swaps out the stock plastic radiator hose connectors on 3.6L automatic-transmission Jeep Wrangler JL and Jeep Gladiator JT models for a one-piece silicone design finished with CNC-machined aluminum fittings. Built from five layers of silicone with heat-resistant embedded fibers, this black hose kit carries a maximum temperature rating of 330°F, giving Wrangler and Gladiator owners added confidence whether they’re crawling over rocks or cruising the highway. The kit arrives complete with both the radiator inlet and outlet hoses, four worm-gear clamps, two zip ties, and a mounting plate.
As part of Mishimoto’s performance-grade Cooling catalog, this specific-fit silicone hose kit is designed to replace factory plastic hose ends that are prone to cracking with age, heat cycling, and off-road vibration. The reinforced five-layer silicone construction is built to improve heat and pressure tolerance compared to the factory connectors, helping protect the cooling system that keeps the 3.6L engine running at a stable temperature. Every Mishimoto silicone hose kit for the Wrangler JL and Gladiator JT platform is backed by the Mishimoto Lifetime Warranty and is also offered in blue and red for owners who want to color-match their engine bay.
