Overview:

The Mishimoto Blue Silicone Radiator Coolant Hose Kit is engineered specifically for the 2018 to 2021 Jeep Wrangler JL equipped with the 2.0L engine. Designed to replace the factory rubber and plastic radiator hoses, this kit offers a durable and reliable cooling solution for the complex cooling systems found in modern Jeep Wranglers. Ideal for Jeep enthusiasts who demand longevity and enhanced performance from their cooling components, these hoses help maintain proper coolant flow and system integrity under demanding conditions.

With multiple cooling circuits managing the engine, battery system, and charge air cooler, the 2.0L Jeep Wrangler requires robust hoses that can withstand heat, pressure, and environmental stress. Mishimoto’s silicone hoses provide a direct-fit upgrade that ensures your Wrangler’s cooling system remains leak-free and efficient.

Key Features:

Engineered for durability and performance, the Mishimoto silicone hose kit offers several advantages over stock components:

• Constructed from four layers of high-grade silicone and heat-resistant fibers for superior strength and flexibility
• One-piece lower radiator hose design eliminates the weak plastic connector found on stock hoses
• CNC-machined aluminum barb and mounting plate replace factory plastic fittings for enhanced longevity
• Resistant to heat, pressure, and coolant chemicals, ensuring reliable operation in extreme conditions
• Available in vibrant blue, with additional color options for customization
• Direct bolt-on fitment with no modifications required

Construction & Design:

The Mishimoto silicone hoses are built to withstand the demanding environment of the Jeep Wrangler JL’s engine bay. Utilizing a multi-layer silicone construction, these hoses resist cracking, swelling, and degradation that commonly affect OEM rubber hoses over time. The integration of heat-resistant fibers adds tensile strength, preventing hose collapse or deformation under vacuum or pressure.

The lower radiator hose features a one-piece design that removes the plastic connector prone to failure on stock hoses. This is paired with a precision CNC-machined aluminum barb and mounting plate, which not only improves durability but also enhances coolant flow by reducing turbulence and potential leak points.

Installation is straightforward with direct OEM replacement fitment for all 2018 to 2021 Jeep Wrangler JL models equipped with the 2.0L engine. No cutting, trimming, or additional modifications are necessary, making it an ideal upgrade for both professional installers and DIY enthusiasts. The kit fits a wide range of Jeep Wrangler trims, including Sport, Rubicon, Sahara, Willys, and special editions such as the 80th Anniversary and Freedom models.
