Features

• Replaces the stock plastic coolant hose connectors with CNC-machined aluminum fittings - eliminating a common failure point prone to cracking under heat cycling and trail abuse
• One-piece silicone hose design reduces the number of potential leak points compared to factory multi-piece plastic and rubber configurations
• 5-layer silicone construction with heat-resistant embedded fibers delivers superior heat and pressure tolerance over the stock rubber/plastic hoses
• Rated to 330°F (166°C) maximum operating temperature for reliable performance in extreme conditions including rock crawling, towing, and high-ambient-temperature off-road use
• Smooth silicone interior promotes unrestricted coolant flow through the radiator circuit
• Red finish adds a bold, purposeful accent to the Wrangler or Gladiator engine bay
• Available in black and blue color options as well
• Backed by Mishimoto's Lifetime Warranty

Product Description

The Mishimoto MMHOSE-JLP-18ARD is a direct-fit silicone coolant hose kit engineered for the 2018+ Jeep Wrangler JL and 2020+ Gladiator JT equipped with the 3.6L Pentastar V6 and automatic transmission. The factory coolant hose system on the JL/JT platform uses plastic connector fittings that are susceptible to cracking, warping, and failure after repeated heat cycles - especially in the demanding conditions that Wranglers and Gladiators are regularly subjected to. Mishimoto addresses this directly by replacing those plastic connectors with CNC-machined aluminum fittings integrated into a one-piece silicone hose design, significantly reducing the number of failure points in the cooling circuit.

Each hose is built from five layers of high-grade silicone reinforced with heat-resistant embedded fibers, rated to 330°F and designed to outlast factory rubber and plastic components through years of rock crawling, trail driving, towing, and daily use. This kit covers both the radiator inlet and outlet hoses and includes all hardware needed for installation. Available in black, blue, and red. Backed by Mishimoto's Lifetime Warranty.
