Here's some pics of a copper & brass radiator core we're running the headers on. The radiator core is for a Caterpillar diesel genset unit. When we overhaul a radiator we run the headers which involves melting all the solder off the header plates where the tubes go through. Once the tubes & header plates [...]

Here's some pics of a Caterpillar & Komatsu haul truck radiators being pressure tested in our test tank. The Cat Radiator is a 793C & the Komatsu Radiator is an 830E. The Komatsu Radiator is a Mesabi which has just under fourteen hundred individual copper tubes. Both radiators will get final detailed & painted after [...]

Here's some before & after pics as well as some progress pics of a radiator recore we did. The radiator is off of a 1980 Kenworth semi truck.

Then there is a small aluminum compressor oil cooler [...]

Here’s some pics of a load of Caterpillar D10 dozer AMOCS radiator cores, or sections, we're rebuilding. Some required some repairing to seal up the leaks from external damage. Others just needed a good cleaning inside & out. After all straightening & repairs have been made each core is individually pressure tested to ensure they [...]
