LS and LT Radiator with Fan for 1958 Chevy Impala/Bel Air/Delray Manual Transmission
Facing the heat of an LS or LT transplant into your 1958 Chevy Impala, Bel Air or Delray with manual transmission requires a cooling solution that keeps temperatures in check and shields your gearbox. The 1973-1974 Nova Radiator (Manual Trans) with Fan uses 100% TIG welded aluminum tanks and a dense core to move heat away fast and fight corrosion. It installs using original mounting points and factory cooling line ports to cut out custom brackets. Even under spirited driving, drivers will notice steady temperature readings and minimal installation time.
Precision TIG Welding Ensures Leak Proof Structure
The all aluminum design uses 100 percent TIG welding to fuse the tanks and core into a single assembly that withstands engine vibration. This welding method creates uniform, smooth joints that resist cracking under load and reduce the chance of coolant seepage. Seamless welds also minimize stress risers and metal fatigue over time, delivering consistent performance mile after mile. By pairing quality aluminum with precision craftsmanship, the radiator maintains low weight without sacrificing structural strength. Manufactured under strict controls in the United States, this approach ensures each unit meets rigorous standards for durability in daily driving and spirited runs.
Aluminum Core with Dense Fin Arrangement for Fast Heat Rejection
A dense core built from quality aluminum provides an expansive surface for rapid heat transfer away from the LS or LT engine, critical when towing or running at high rpm. Fine, closely spaced fins increase airflow contact and accelerate cooling, helping maintain stable operating temperatures under varied driving conditions. Aluminum's superior thermal conductivity draws heat from the coolant faster than conventional designs, preventing hotspots that can stress head gaskets or seals. Consistent engine temperature also safeguards manual transmission fluid from thermal degradation. Drivers will notice steady gauge readings even in stop and go traffic or on extended highway cruises.
Direct Fitment on 1958 B Body Manual Transmissions
Tailored for 1958 Impala, Bel Air and Delray B Body frames with manual transmission, this radiator bolts in using original mounting tabs and factory cooling line ports. There is no need for frame modifications or custom brackets, so installers save time and avoid alignment issues. This precise match preserves the classic engine bay layout and keeps adjacent components clear of obstructions. The straightforward installation process provides confidence in proper fitment and reduces the chance of leaks or loose connections. Enthusiasts can return to the road faster with a neat, reliable setup.
Classic Finish Choices for Corrosion Protection and Visual Appeal
Owners can choose a bare aluminum finish to showcase classic under hood styling or opt for the protective black epoxy coating to ward off corrosion and road debris. The natural aluminum surface resists pitting and oxidation, while the epoxy layer forms a barrier against moisture and salt in more challenging climates. Both treatments contribute to long term core integrity and keep coolant passages free from rust. A clean finish also simplifies routine maintenance, as smooth surfaces are easier to wipe down and inspect for damage. This choice allows a balance between period correct appearance and enhanced weather resistance.
