we've had the same problem across the board with C-15s, 3406s, and C-9s. THe larger motors are generally oil coolers. Almost all of our motors have had reman heads put on them due to a cracked head. Generally all these trucks are at the 700,000+ miles club. If your not building high amounts of pressure in the radiator it should just be a oil cooler.
