Description

CATERPILLAR EXCAVATORS:
• Caterpillar 311C/312C/314C S4K/3064 4.3L Diesel (2002-2012)


IMPORTANT:
Mitsubishi OEM oil cooler for the S4K engine, which Cat brands as the 3064. Identical part to Cat B135-2403 — same cooler, different OEM part number. Fits Cat 311C/312C/314C excavators (2002-2012).
Do NOT confuse with the S6K (6-cylinder) oil cooler M34339-02102 / Cat B125-2970. The S4K is the 4-cylinder 4.3L version, the S6K is the 6-cylinder 6.4L. They use different coolers that are not interchangeable.
Failure symptoms: milky oil on dipstick, oil mixing into coolant, elevated oil temps, external oil weep. Replace all gaskets and seals during installation.
⚠️ Confirm S4K/3064 (4-cyl) — not S6K/3066 (6-cyl).
