Frequently Asked Questions

What radiator fits a Caterpillar 320D excavator?

Broken Tractor carries several radiator options for the Cat 320D, including part 265-3624 (fits 320D, 320D FM, 320D FM RR, 320D L, 320D LN, 320D LRR and 320D RR), part 265-3617 (fits 320D and 320D L) and radiator core 3263870, which also covers 320D GC. Because more than one radiator was used on the 320D, the correct one can depend on your serial number. Match the part number on your old radiator, or call our parts team at (800) 909-7060 to confirm fitment before you order.

Which Caterpillar excavator models do your radiators fit?

We carry radiators and radiator cores for a wide range of Cat excavators, from the 225, 225B and 229 through the 311, 312, 315B, 318C, 319C, 320, 321D, 322, 323D, 324D, 325, 329D, 330, 336D, 340D, 345D and 349 families, up to the 349F and 352F. Coverage spans the original and A series as well as the B, C, D, E and F generations. Each listing names the exact models it fits, so check your model and suffix, such as L, LN or FM, against the product before ordering.

Do you carry radiators for Cat mini excavators?

Yes, Broken Tractor offers radiators for several Cat mini and compact excavators. These include part 169-1145 and an FL version, 169-1145-FL, for the 303.5 and 303.5C, part 245-2138 for the 305, and part 378-1255 for the 305E, 305E2, 305E2 CR, 305.5E, 305.5E2, 305.5E2 CR and 306E2. We also carry a radiator for the 308B.

What is the difference between a Cat excavator radiator and a radiator core?

Broken Tractor sells both complete radiators and radiator cores for Cat excavators, and the listing title shows which one you are getting. For example, the 320C has a complete water radiator, part 2364430, as well as engine radiator core 1932767, while the 320B has a combined oil cooler and radiator core, part 1843896. The best way to get the right one is to match the part number stamped on the unit you are replacing.

What radiator fits a Caterpillar 349 or 345D excavator?

Broken Tractor offers radiator part 383-6407 for the 345C MH, 345D, 345D L, 349, 349D, 349D L, 349D2 and 349D2 L in two versions, an all-metal radiator and a dimple tube core radiator (SKU 383-6407-DT). For the newer 349E, 349E L, 349E L-VG, 349F, 349F L, 349F LXE and 352F, we carry radiator part 335-4191. Confirm your exact model and suffix against the fitment list on each product.
