1984-1989 Chevy Corvette LS Swap Radiator for Auto and Manual Transmissions
You are installing an LS swap in a 1984-1989 Corvette Y Body and you need reliable cooling that fits both automatic and manual transmissions. This 1984-1989 Corvette Radiator (Auto and Manual Trans) matches factory frame rails and hose outlets, preventing trimming or adapters around steering and air conditioning lines. Constructed with a TIG welded aluminum core and tanks, it eliminates porosity and withstands vibration and pressure surges, ensuring leakproof strength under spirited driving or towing. With direct fit for both automatic and manual setups in the classic Corvette chassis, coolant flow stays consistent from daily road use to track sessions.
Precision TIG Welding for Leakproof Durability
This radiator uses TIG welding to join aluminum tanks and the core with unparalleled seam quality. The controlled heat input and precise filler feed ensure smooth joints that resist porosity and prevent coolant leaks under sudden pressure spikes and persistent vibration. With each seam verified for integrity, the assembly maintains structural strength during spirited drives or towing heavy loads. This weld method yields uniform bonds that stand up to repeated thermal cycles without cracking or fatigue. Technicians benefit from a predictable production process that reduces rework and ensures every unit performs consistently in demanding swap applications.
High Quality Aluminum Core for Rapid Heat Transfer
Every component of this radiator is crafted from premium aluminum to take advantage of its natural ability to conduct heat away from the engine efficiently. The low density of the material allows for a thinner core profile that fits neatly within the tight confines of a Y body chassis while still providing ample surface area for cooling. Aluminum also resists corrosion in the coolant passages, helping preserve flow capacity over many seasons of use. Its combination of light construction and high thermal conductivity makes it ideal for daily driven cars and track vehicles alike. By shedding heat quickly, the radiator keeps engine temperatures stable even under rigorous driving conditions.
Custom Coating Options for Lasting Environmental Protection
Owners can choose a polished bare finish to showcase the raw aluminum or opt for a black epoxy coating applied in the USA to shield against moisture and road salts. The bare version highlights the natural metal and relies on aluminum’s inherent corrosion resistance for a classic underhood look. The epoxy layer adds an extra barrier against airborne contaminants and harsh winter chemicals, preserving the appearance and surface integrity over time. Both finishes are designed to maintain the radiator’s cooling efficiency without adding insulation that could trap heat. This choice lets builders match the underhood styling to their personal taste while ensuring long lasting defense against wear.
Direct Fit Design for Automatic and Manual Transmission Layouts
Specifically engineered for 1984 to 1989 Corvette Y bodies, this radiator aligns precisely with factory frame rails and stock hose outlets. There is no need to trim or adapt steering and air conditioning lines, simplifying the installation process and preserving original clearances. Whether connected to an automatic torque converter or a manual transmission, the unit ensures consistent coolant flow throughout every driving scenario. By delivering plug and play fitment, it reduces custom work and accelerates project completion. This precise integration allows builders to focus on performance tuning rather than fitment issues.
