Radiator

Engineered specifically for 1997-2004 Chevrolet C5 Corvettes, the Mishimoto Performance Aluminum Radiator delivers 134% more cooling capacity than the factory radiator - keeping coolant temps stable whether you’re running laps or pushing hard on your favorite stretch of road.
--
The 2.2-inch thick core is the headline upgrade. At more than double the factory core thickness, it moves thermal energy into the airstream faster and keeps coolant outlet temperatures consistent across extended sessions. The enlarged in-tank transmission cooler adds another layer of drivetrain protection - dropping transmission fluid temps under hard use and reducing heat-related wear when you push the C5 hardest.
--
Installation is complete right out of the box. Transmission line fittings for every C5 model year and new rubber mounting bushings are included - eliminating the adapter-hunting and leaking connections that owners of high-mileage C5s know well. Full aluminum construction with TIG-welded end tanks replaces the factory components prone to cracking under heat cycling, so you’re getting a total cooling system refresh alongside the performance upgrade.
--
Whether your C5 is stock or carrying performance modifications, the oversized core is sized to handle the thermal load. Backed by the Mishimoto Lifetime Warranty, this is the direct-fit cooling upgrade built for C5 owners serious about keeping their car on the road - and on track.
