Superseding & Cross-Reference Numbers:

• Caterpillar publishes no replacement or superseding number for 108-2387.
• Caterpillar lists radiator seals 4P-9942 and 4P-9943 with this module, stocked separately - the seals are what make a module stack watertight and are normally renewed at the same time.

Key Notes:

• Part Number: 1082387 (Caterpillar reference 108-2387)
• Type: Modular radiator core section - one module, not a complete radiator
• Construction: Caterpillar improved multi row module design, stacked side by side to make up the radiator
• Dimensions: 1280 mm x 137 mm
• Material: Structural, carbon and alloy steel
• Weight: 40.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces a radiator core module on Caterpillar D5M and D6M track-type tractors, 938G through 962G wheel loaders, IT toolcarriers, the 527 track skidder and the 561M pipelayer
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: This is ONE module. A machine's radiator is built from several of these stacked together, so count how many your machine carries and how many are damaged before ordering. End tanks, seals, frame and hardware are not included. Ships LTL freight.

Common Use Case or Symptoms:

Order these when one section of a modular radiator is leaking or plugged - the point of the design is that a damaged module comes out on its own without touching the rest of the stack, which turns a full radiator replacement into an afternoon.

Why Choose Broken Tractor?

• ✅ One Module At A Time: Modular construction means a single damaged section is replaced rather than the whole radiator - that is the entire reason Caterpillar built it this way.
• ✅ Nine Machine Families: Dozers, wheel loaders, toolcarriers, a track skidder and a pipelayer all share this module.
• ✅ Seals Named Separately: The two end tank seals are identified in the listing, because a module goes back in dry without them.
