Frequently Asked Questions

What radiator fits a Komatsu WA500-6 wheel loader?

Broken Tractor carries two radiators listed for the Komatsu WA500-6: part numbers 425-03-32212 and 425-03-32222. Because more than one part number fits this model, match the number on your existing radiator before ordering. For the newer WA500-7, we offer radiators under part numbers 425-03-42210 and 425-03-42220.

Which radiator do I need for Komatsu WA180-3 parts?

We carry two radiator options for the Komatsu WA180-3: part numbers 417-03-A1403 and IR-417-03-A1403. Compare the part number on your current radiator with these listings to choose the right one, or ask our parts team to verify fitment before you order.

What radiator fits a Komatsu WA430-6 loader?

Broken Tractor offers two radiators listed for the Komatsu WA430-6: part numbers 424-03-41111 and IR-WA430-6. If you run the earlier WA430-5, we carry radiator 421-03-31115, which also fits the WA450-5L and WA470-5. Matching the part number from your old radiator is the surest way to get the correct unit.

Does the radiator for a Komatsu WA380 depend on the serial number?

Yes, some WA380 radiators are serial number specific, so confirm your serial before ordering. For example, radiator 423-03-61111 fits the WA380-3L from serial A50001 up, while 423-03-A1210 is also listed for the WA380-3L. Other versions use different parts, including 424-03-11203 for the WA380-1 LC, 423-03-31212 for the WA380-5H and 423-03-41110 for the WA380-6. If you are unsure which one you need, call (800) 909-7060 with your model and serial number.

Can I buy just a radiator core for a Komatsu wheel loader instead of a full radiator?

It depends on the model. We carry both full radiator assemblies and radiator cores, depending on the machine. For example, the Komatsu WA600-6 is covered by radiator core 426-03-37521, while models like the WA250-6 and WA320-6 are covered by full radiators, part numbers 418-03-48151 and 419-03-48110.
