Caterpillar 265-3625 Radiator

Fitment and Service Notes

The 320D family is the highest-volume excavator line on the used market across Africa, the Middle East and Latin America, and its cooling package changed several times in production. The part-number chain runs 312-8338 → 481-3475 → 265-3624 → 265-3625, with the later builds more commonly quoted as 326-3870 (checked against aftermarket listings, August 2026). 265-3625 is the aluminum-core number listed for the 320D, 321D and 323D — so if your machine is an early-to-mid D-series build, this is usually the one, but the model name alone is not enough.

The reliable path is the same as with every Cat cooling part: your machine serial number plus photos of the old unit, so we can compare core height, tank shape and bracket positions. If the old radiator still carries a legible number, send it — we cross-reference it directly. For the later 320D-family builds the equivalent page is the Cat 320D radiator 326-3870, and the bigger 330D/336D class (C9 engine) uses 245-9359.

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.
