How to Rebuild Heavy Equipment Radiators

Heavy equipment cooling systems are intentionally constructed with the ability to be rebuilt multiple times before they are replaced, unlike traditional auto radiator systems. Stronger materials, including brass and copper, are used during assembly so the radiator can withstand higher stress. While professional radiator shops possess the machinery and manpower to rebuild your heavy equipment radiator quickly and effectively, some drivers may want to learn the art of repair themselves to save money over the radiator's life.

Instructions

1

Remove the bolts from the radiator tanks with the proper-sized wrench. Cut any rusted bolts free from the tanks.

2

Insert each part of the radiator into a hot tank and leave for the appropriate amount of time according to the hot tank specifications for a complete cleaning. Clean the outside of the radiator with a wire brush.

3

Assemble the radiator and add coolant. Watch for any visible leaks.

4

Plug the radiator connections with stoppers. Add pressurized air from an air compressor before plugging the last connection.

5

Fill a large clear tank with water. Insert the radiator into the tank and watch for air bubbles. Identify the origin of the bubbles to determine where the radiator system leaks exist.

6

Replace leaking radiator parts with sealed components from a scrap yard or local heavy equipment mechanic. Test the system in the water-filled tank after repairs to confirm the leaks have stopped.
