Why upgrade

The Mishimoto performance aluminum radiator for the Jeep Wrangler YJ and TJ is the ideal upgrade to the stock Wrangler radiator. It is designed and specifically engineered to maximize cooling efficiency by up to 20-percent, boost engine functions and protect your car from overheating. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.

Features

• Proven 20% improvement in fluid cooling efficiency and 68% more fluid capacity than the factory unit give the Wrangler the thermal headroom for trail abuse, towing, and warm-climate wheeling.
• Strutted tubes in the top and bottom 5 rows increase core strength — resisting the chassis flex and impact stress that destroy lesser radiators on the trail.
• 1.3 bar high-pressure radiator cap and Magnetic Drain Plug included — raises the coolant boiling point and captures harmful debris, complete out of the box.
• Two-row, 1.88-inch thick aluminum core with stamped header plate and TIG-welded end tanks replaces the factory components that crack under the heat and flex of off-road use.
• Stamped header plate ensures a strong bond between end tanks and core — resisting cracking and leaks through the flex and vibration cycles of trail use.
• Confirmed direct fit for the 1987–2006 Jeep Wrangler TJ/YJ with 2.5L/4.0L engine — no cutting, fabricating, or adapter work required.
• Two-row core with strutted tubes handles the thermal and structural demands of stock and lifted Wrangler builds running trail, tow, and overland duty.
