Mishimoto MMRAD-C5-97 Performance Aluminum Radiator for Corvette - C5

The Mishimoto MMRAD-C5-97 is a direct-fit performance aluminum radiator engineered as a significant cooling upgrade over the factory unit. Built specifically for the 1997–2004 Chevrolet Corvette C5, this radiator delivers dramatically improved thermal management for street driving, track days, and everything in between.

At the heart of this upgrade is a 2.2-inch thick brazed aluminum core — more than double the thickness of the stock radiator core. This oversized core moves heat into the airstream faster and maintains consistent coolant outlet temperatures even during extended high-performance sessions. The result is 134% more cooling capacity compared to the OEM radiator.

Key Features:

• 134% more cooling capacity than the factory radiator
• 2.2-inch thick dual-row brazed aluminum core for superior heat dissipation
• Full aluminum construction with TIG-welded end tanks — more durable than factory plastic/aluminum units prone to cracking under heat cycling
• Enlarged in-tank transmission cooler lowers transmission fluid temps under hard use and reduces heat-related drivetrain wear
• Direct drop-in fit — no cutting or modification required
• Includes transmission line fittings for all C5 model years and new rubber mounting bushings for a complete installation
• Includes high-pressure 1.3 bar radiator cap to raise the coolant boiling point for improved system efficiency
• Magnetic drain plug captures metallic debris and fragments to protect the cooling system
• Backed by the Mishimoto Lifetime Warranty

Whether the C5 is stock or modified, the MMRAD-C5-97 is sized to handle the thermal load. Full aluminum construction replaces the factory components that are prone to cracking under heat cycling, providing a complete cooling system refresh alongside the performance upgrade.
