This is a Freightliner M916A1 military truck radiator that came in for an overhaul. Once we got the radiator disassembled we discovered that the original radiator core was heavily corroded and pitted from the inside out. So we had to re-core the radiator which means we installed a new radiator core. Since this is a bolt-on or bolt together style radiator we clean & blast the top and bottom tanks and the side brackets and then bolt them all together to the new radiator core. In this case, we re-cored the radiator with a high efficiency 4-row radiator core. If your radiator has seen better days and needs to be fixed up and given a new life, give us a call or come on by to see us at our fully equipped machine and radiator shop located here in Las Vegas, Nv.
