Product Overview
Oil running too hot, coolant contaminated with oil, or leakage around the cooler housing can point to a failed cooler after the seals, housing, pressure sources, and engine condition are checked.
This stacked-plate engine oil cooler replaces Yanmar 124100-5710 on compatible TNV engine builds. Compare core dimensions, port pattern, sealing faces, and engine build code; CK20 and CK30 fit depends on the installed engine.

Compatibility Notice

Frequently Asked Questions
Q: Can a failed oil cooler put oil in the coolant? A: Yes. A leak between circuits can allow the higher-pressure fluid to cross, but head-gasket and casting faults must also be considered.
Q: Does this fit every Komatsu CK20 or CK30? A: Only when the machine uses the matching Yanmar engine and cooler configuration.
Q: How do I confirm fitment before ordering? A: Match the original reference number, equipment model and serial number, dimensions, connector or mounting details, and the product photos. Do not rely on appearance alone.
Q: Is this made by the original equipment manufacturer? A: No. This is a new aftermarket part. Brand names and model numbers are used only to identify compatible equipment.
