Mishimoto 03-09 Toyota 4-Runner / GX470 4.7L Performance Aluminum Radiator

The 2003-2009 Toyota 4Runner V8 is known for its ruggedness, reliability, and off-road capability, but as they grow older the stock parts are starting to show their age. Over time, the factory radiator can develop issues such as leaks, corrosion, or clogging. Upgrading to a new Mishimoto performance aluminum radiator can prevent these problems before they occur, saving you from potential breakdowns on the trail. For those who use their 2003-2009 Toyota 4Runner for off-roading, this radiator can handle the additional strain and heat generated during these activities, providing better reliability and performance in rugged conditions. Our direct-fit radiator features a 40mm thick core for increased cooling capacity. Constructed entirely from aluminum with durable, TIG-welded end tanks, it includes an efficient in-tank liquid-to-liquid stacked plate transmission cooler for optimal transmission fluid temperature control. The radiator also comes with a magnetic drain plug to capture metallic debris in your cooling system and is backed by the Mishimoto Lifetime Warranty for peace of mind.

Mishimoto performance radiators are designed and engineered to maximize cooling efficiency, boost engine functions, and, most of all, protect your engine from overheating. Many stock radiators can't handle the additional heat that comes higher horsepower levels. So, swap out your stock radiator for an all-aluminum Mishimoto.

Key features and benefits of Mishimoto performance radiators include:
• Available for universal and exact fit applications (no cutting or modifications required)
• All-aluminum construction for optimal heat dissipation, improved strength, and reliability
• Increased cooling capacity due to their massive core size
• 100 percent brazed aluminum core for minimal distortion, low stress, and clean joints
• Available in various sizes with 2-row or 3-row cores
• TIG-welded for clean, strong welds and increased durability
• Magnetic drain plugs capture metallic debris or fragments
• Included high-pressure 1.3 bar cap raises the coolant boiling point for greater safety and efficiency
• Automatic transmission and accessory coolers included where applicable
