FAQ

Q: How do I confirm this oil cooler fits my specific Komatsu excavator model?
A: First, locate your engine model number on the engine nameplate—it should read 6D125-3P. Then, check the current oil cooler part number (stamped on the cooler body or in your parts manual). If it matches 6150-61-2111 or 6150-61-2110, this unit is a direct replacement. If you have any doubts, please provide your machine serial number and we can verify compatibility before shipping.

Q: What are the common signs that my oil cooler needs replacement?
A: Key indicators include: visible oil leaks around the cooler core or gasket area, emulsified oil (milky appearance) in the oil pan indicating coolant contamination, elevated engine oil temperature readings on the dashboard gauge, or visible physical damage (bent fins, cracks, or corrosion) on the cooler core. If you notice any of these issues, replace the cooler immediately to prevent engine damage from overheating or inadequate lubrication.

Q: Is any special installation procedure required for this aftermarket oil cooler?
A: Installation is straightforward and mirrors the OEM procedure. We recommend replacing the oil cooler gaskets and O-rings (sold separately) during installation to ensure a proper seal. Torque the mounting bolts to the manufacturer’s specifications (typically 25-30 Nm for M8 bolts). After installation, run the engine and check for leaks at operating temperature. Allow the engine to cool before tightening any connections if minor seepage is observed. Always use fresh engine oil and a new oil filter after cooler replacement.
