Description

CATERPILLAR EXCAVATORS:
• Caterpillar 320B/320C/320D S6K/3066 6.4L Diesel (1996-2012)


IMPORTANT:
Mitsubishi OEM oil cooler for the S6K engine, which Cat brands as the 3066. Identical part to Cat B125-2970 — same cooler, different OEM part number. Fits Cat 320B/320C/320D excavators (1996-2012).
If your supplier stocks Cat numbers, order B125-2970 instead. If they stock Mitsubishi numbers, order this part. Both are functionally identical drop-in replacements.
Do NOT confuse with the Mitsubishi S4K oil cooler (M34239-02100 / Cat B135-2403) — that is the 4-cylinder version for Cat 311C/312C/314C excavators.
Failure symptoms: milky oil, oil in coolant, elevated oil temps, coolant loss. Replace all gaskets during installation.
⚠️ S6K (6-cyl) — not S4K (4-cyl). Verify engine before ordering.
