This is a LeTourneau Mesabi L&M style radiator for an L1850 loader that we rebuilt. Each of the individual Mesabi L&M tubes were removed for ultrasonic cleaning, boiling, & polishing. All of the rubber grommet seals were replaced in the tanks before the rebuilt tubes were re-installed back into the radiator. This LeTourneau L1850 Mesabi L&M style radiator consists of an oil cooler section, a hi-temp radiator section, and a lo-temp radiator section. Each section is individually pressure tested in our test tank.
