1962-1967 Chevy II/Nova X-Body LS Swap Radiator for Auto Trans
The 1962-1967 Chevy II Radiator (Auto Trans) addresses the need for stable heat management when fitting an LS engine and automatic transmission into a Chevy II or Nova X Body platform. This radiator takes on that challenge with a calibrated fit that matches chassis rails, factory frame brackets and original fan shroud mounts. Built around full aluminum tanks and a dense fin core joined with TIG welding for consistent coolant circulation, it resists corrosion under repeated thermal cycles and rejects heat quickly during spirited driving or long hauls. Mounting cooler lines for both 4L60E and 4L80E transmissions to integrated ports eliminates the need for adapters or modifications and streamlines installation to keep project timelines on track.
Precision TIG Welding for Reliable Seals
The radiator employs TIG welding across all joints, fusing aluminum tanks and core panels at the molecular level. This process creates uniform seams free of porosity and reduces internal turbulence in coolant passages. Builders benefit from a structure that resists leaks when subjected to repeated temperature swings and track day demands. Because TIG welding adds minimal spatter, the channels remain unobstructed and coolant flow stays steady under spirited driving or when towing heavy loads.
High Quality Aluminum Core for Fast Heat Rejection
At the heart of this radiator is a dense fin aluminum core that maximizes surface area for heat exchange. With aluminum's innate conductivity, excess thermal energy is drawn from the LS engine block and released into passing air almost instantly. The minimal mass of the core allows the cooling system to react rapidly to sudden load changes or sustained high temperature conditions. Owners will notice lower coolant temperatures during extended runs or stop and go traffic, preserving engine performance and reducing wear.
Bare and Epoxy Coatings for Corrosion Resistance
Choose between a natural bare aluminum finish or a black epoxy coating tailored to your project needs. The bare option allows direct metal to air contact for peak thermal efficiency without added upkeep. Alternatively, the epoxy finish shields against moisture, road salt, and airborne debris while still permitting efficient heat transfer. Coatings are applied in a controlled environment to guarantee uniform coverage and strong adhesion that endures through many seasons of use. This flexibility helps match both visual style and protection requirements.
Direct Fit to 4L60E and 4L80E Cooler Ports
Designed to mount directly to the original frame brackets on 1962 to 1967 Chevy II and Nova X Body chassis, this radiator preserves factory alignment. Integrated ports accept transmission cooler lines for both 4L60E and 4L80E units without the need for adapters or extra fittings. That plug in configuration cuts installation time while sealing points remain secure against fluid leaks. Retaining the stock fan shroud mounts ensures any electric or mechanical fan operates at its intended efficiency. This precise fit lets builders complete LS swaps with minimal adjustments.
