Komatsu PC200-8 Radiator 20Y-03-41651

Fitment and Service Notes

The PC200-8 is one of the highest-volume excavators on the used market in Africa, the Middle East and Southeast Asia — which is exactly why radiator fitment matters: Komatsu changed the cooling package several times across the 8-series production life, and the earlier core 20Y-03-42451 was superseded by 20Y-03-41651. Ordering by machine model alone is how wrong radiators end up on site. The reliable path is the serial number, which ties the machine to its build spec, plus photos of the old unit so we can compare core height, tank shape and bracket positions.

If the old radiator still has a legible number on the tank or core, send it — we cross-reference 20Y-03-42451 and related numbers directly to the correct current unit. Aluminum is the standard core for 8-series builds; copper-brass is an option mainly on older machines and costs more (see our aluminium vs copper radiator guide for the trade-offs).

Plan your order around the whole cooling package, not just the radiator: the PC200-8 intercooler 20Y-03-41131 (listed at about $715, August 2026) and the hydraulic oil cooler sit in the same stack, and a worn fan clutch will do the same damage to a new radiator that it did to the old one. Typical aftermarket pricing for this size class runs roughly $250–600, against an OEM price in the $900–1,800 territory.

For the broader picture — failure signs, replacement procedure and cost logic — see our Komatsu parts catalog guide, the radiator replacement guide and the radiator failure signs guide. If your machine is a Cat 320D, the equivalent radiator is 326-3870 — see the Cat 320D radiator page for that family.
