Description

CATERPILLAR EXCAVATORS:
• Caterpillar 320D/320D2/321D/323D C6.6 6.6L Diesel (2007-2018)

CATERPILLAR WHEEL LOADERS:
• Caterpillar 924H/928H/930H C6.6 6.6L Diesel (2006-2015)

CATERPILLAR MOTOR GRADERS:
• Caterpillar 120M/12M/140M C6.6 6.6L Diesel (2007-2016)


IMPORTANT:
This is an ASSEMBLY (cooler core plus housing) for Cat C6.6 engines. If you only need the core, order the Perkins brick-type core P2486A002 instead. Cat C6.6 = Perkins 1106C-E60TA — same engine block.
Fits Cat 320D/320D2/321D/323D excavators and 924H/928H/930H wheel loaders. This is NOT the same cooler as the earlier 3066/S6K applications (B125-2970) — different engine platform entirely.
Failure symptoms: milky oil, oil in coolant reservoir, elevated oil temps under load, unexplained coolant loss. Inspect housing bore for scoring before installing new cooler. Replace all gaskets and O-rings.
⚠️ Confirm assembly vs core-only needed before ordering.
