Caterpillar 245-9359 Radiator

Fitment and Service Notes

The 330D and 336D are staple machines on mining and quarry sites across Africa, the Middle East and Latin America, and the 245-9359 is the radiator number quoted for the C9-engine versions of that family (checked against aftermarket listings, August 2026). The same caveat applies as with every Cat cooling part: D-series machines changed cooling packages across production years, so the model name alone is not enough. The reliable path is your machine serial number plus photos of the old unit, so we can compare core height, tank shape and bracket positions against the correct unit.

If the old radiator still carries a legible number, send it — we cross-reference it directly. On older 330-size machines you may also see copper-brass cores; aluminum is the standard for D-series builds and is what 245-9359 listings carry (see our aluminium vs copper radiator guide for the trade-offs). For the 320D family — the smaller class that shares most of the same failure patterns — the equivalent number is 326-3870; we cover it on the Cat 320D radiator page.

Plan your order around the whole cooling package, not just the radiator: on the Komatsu side the PC200-8 radiator 20Y-03-41651 and its intercooler 20Y-03-41131 (listed at about $715, August 2026) sit in the same stack logic, and a worn fan clutch will damage a new radiator exactly as it damaged the old one. Typical aftermarket pricing for this size class runs roughly $250–600, against an OEM price in the $900–1,800 territory — quality aftermarket parts are cross-referenced to the OEM number at 30–60% below OEM list.

For the broader picture — part numbers across the Cat lineup, failure signs and replacement logic — see our Caterpillar radiator guide, the heavy equipment cooling system parts guide and the radiator replacement guide.
