FAQ

Q1: How can I confirm this oil cooler will fit my specific Komatsu machine?
A1: The most reliable method is to match the part number. Locate the oil cooler on your Komatsu 4D105-5 engine and verify that the stamped part number is either 600-651-142 or 6134-61-2113. You can also provide your machine’s model and serial number to our support team for verification.

Q2: What are the signs that this oil cooler needs replacement?
A2: Common indicators include external oil leaks around the cooler assembly, engine oil mixing with coolant (or vice-versa), and consistently higher-than-normal engine oil temperatures, which can lead to reduced lubrication and accelerated engine wear.

Q3: Do you provide technical support for installation?
A3: Yes. We can supply general installation guidelines and torque specifications. For complex repairs, we always recommend consulting the official Komatsu service manual or utilizing a certified heavy equipment mechanic to ensure proper installation and system bleeding/purging.
