55-57 Tri-5 Chevy Radiat or (V8 Mount)

The 55-57 Tri-5 Chevy radiator with V8 mount from Cold Case Radiators is purpose-built for classic Chevrolet enthusiasts restoring or upgrading first-generation Tri-Five models (1955–1957). This aluminum radiator addresses a critical cooling challenge: factory cooling systems on V8-powered Tri-Fives often struggle with sustained heat dissipation, especially in street and performance driving. Whether you're building a restomod, installing modern engine modifications, or simply replacing an aging original radiator, this polished aluminum unit delivers reliable thermal management while maintaining the clean aesthetic of your classic chassis.

Constructed from aluminum with a polished finish, the 55-57 Tri-5 Chevy radiator features a center inlet and passenger-side outlet configuration designed to integrate seamlessly with Tri-Five plumbing. Measuring 23.5 inches wide by 23.5 inches tall with a 3-inch core depth, it fits within the original radiator cavity while providing significantly improved cooling capacity compared to vintage cores. The lightweight aluminum construction (21.7 lbs) reduces parasitic weight while enhancing heat transfer efficiency—critical for V8 engines that generate substantially more thermal load than the original inline-six designs. The polished finish not only looks factory-correct when viewed through the grille but also reflects radiant heat, aiding overall engine bay climate control.

This radiator is ideal for Chevy V8 powerplants in fullsize 1955–1957 models and is especially valuable for builders upgrading from original six-cylinder cooling systems. Installation requires correct water-pump and hose routing to the center inlet and passenger outlet—compatibility with your specific V8 block and intake manifold configuration should be verified before purchase. Mechanics and restorers appreciate Cold Case's engineering: the polished aluminum construction resists corrosion, the dimensions preserve original trim fit, and the proven thermal capacity eliminates the guesswork of sourcing vintage cores. Whether you're tackling a weekend cruiser or a ground-up frame-off restoration, this radiator ensures your Tri-Five stays cool under load.
