Cummins 855 Oil Cooler Repair Service

Minor issues like external leaks or gasket failures can sometimes be repaired, but cracked cores, severe internal fouling, or corrosion typically require full replacement. We recommend OEM-equivalent replacement units for long-term reliability rather than repeated repairs on heavily degraded coolers.

Common warning signs include oil mixing with coolant (milky fluid), engine overheating, low oil pressure, metallic debris in the oil, or visible leaks around the cooler housing. Any of these symptoms warrant immediate inspection to prevent further engine damage.

The Cummins 855 engine platform powers heavy-duty trucks, construction and earthmoving equipment, industrial generators, air compressors, and various off-highway machinery.
