Boil-out, Hot Tank Cleaning

Our certified technicians expertly clean your engine parts with this traditional hot tank cleaning method that eliminates rust, scale, dirt etc. leaving your parts like new. Our professionals carefully “boil-out” your tank, unplugging any hard water and old coolant deposits.

Recoring Service for Radiators

Recoring repair is available if your radiator cannot be restored. Our certified technicians use your existing tanks and brackets to create a similar or custom-designed improved radiator. This ensures the perfect fit for your radiator core.

Rebuild Service for Radiators

Affton Radiator Services offers custom rebuilds on any type of radiator. From cars to large service trucks, mega watt generators to mining equipment, we carry the parts and expertise to make sure your radiator is working better than ever. Take advantage of our free pick-up and delivery along with fast, attentive service.

CAT Radiator Tank Rebuilding Service

Caterpillar (CAT) radiator tank rebuilds are available for any CAT Folded, Modular and AMOC Tank. Along with CAT core repair, this rebuilding service can be a cost-effective way to replace a broken radiator tank. As always, pick-up and delivery is available with fast service. Call or visit us today to make an appointment for a rebuild with our heavy duty, certified technicians.

CAT Repair Services

Our Caterpillar (CAT) core repair service features “Folded” or “Modular” core repair which tactfully replaces a single core with anywhere from nine to ten individual core units, making future replacements easier to diagnose and replace. Along with Folded or Modular core repair, CAT AMOC core repair is available as well for any cleaning, replacement or rebuilding needs.

New CAT Cores with Extended Warranty

New CAT Folded Cores and new CAT AMOC Cores are available with an extended, one year warranty, as opposed to the original equipment manufacturer (OEM) six month warranty. Affton Radiator Service’s commitment to service and support means you get the most from your core repair, every time.

Cleaning Services

Going beyond just power washing, our industrial radiator and heat exchanger services involve, where necessary, solder dipping radiators similar to what the manufacturer does with the new core, and detailed cleaning and re-tubing service for Mesabi radiators. Ultrasonic cleaning and “boil-out” hot tank cleaning is also available.
