Johnsons Radiator for 1959 Buick Lesabre, Invicta, or Electra all models with LS Swap (or LT) in mind. This Radiator was designed in collaboration with Hammer Fab and Johnsons Radiator Works specifically for LS/LT swaps. It bolts directly into the stock location and has the correct inlet and outlet port sizes for modern LS/LT hookup. It is designed to accept at least 700HP heat demands. We recommend installing a separate transmission cooler which is why this one does not come with a built in cooler. Accepts a modern billet or standard radiator cap and has overflow tube. Also has a petcock drain at the bottom. It you plan on installing our front suspension with splined sway bar this will clear and fit perfectly! Made in USA. Place your order here and we will take care of the rest. Please allow 2-4 weeks for production. These are made to order and will be drop shipped to you.
Our BIGGEST questions - Why choose JRW? And why copper/brass? To start, copper has a 40% MORE thermal cooling efficiency over aluminum. Paired with a proprietary serpentine fin design we use - designed by Walker Radiator - with over 600,000 louvers in each radiator. This eliminates air boundary build up inside the core.
Vehicles from the 1930’s have up to 40% less core size than today’s cars/trucks. Majority of todays cars/trucks are equipped with 400-500hp, AC condensers, and are daily driven demanding a resilient cooling system - and that’s where we come into play.
