Frequently Asked Questions

What radiator fits a Komatsu HM350-2 articulated dump truck?

Broken Tractor carries a Komatsu radiator built for the HM350-2 articulated dump truck, listed under SKU 1771-073-1010. HM series cooling components are machine-specific, so confirm your serial number and generation suffix before ordering. Matching the part number on your existing radiator is the surest way to get the right fit.

Does the Komatsu HM400-5 have a left and right radiator?

Yes, radiators for the Komatsu HM400-5 are offered as separate left and right assemblies. Verify which side you are replacing before you order, since the left and right units are listed separately. We also carry an additional radiator for the HM400-5 under SKU RSH-930171.

Will a Komatsu HM400 radiator fit an HM350?

No, radiator and cooling components are machine-specific and do not interchange between the Komatsu HM350 and HM400 series. An HM350-2 needs a radiator made for the HM350-2, and an HM400-5 needs one made for the HM400-5. Always check the model and serial number on your truck before choosing a part.

How do I make sure I order the right radiator for my Komatsu articulated dump truck?

Start with your truck's model, serial number and generation suffix, since cooling parts for HM series trucks can vary by these details. If your old radiator has a part number, match it against the SKU on the listing, and on the HM400-5 confirm whether you need the left or right assembly.
