Here’s some pics of an aluminum oil cooler we had in for repairing & rebuilding. The cooler is an all aluminum bar-and-plate heat exchanger that came off of an Epiroc drill rig. The cooler came in leaking due to some cracked tubes. We cut the tanks off the original core & then machined them to size. The tanks are then tig welded to a new heavy duty core. After all the tig welding is complete we pressure the cooler to ensure it has zero leaks.
