Key Notes:

• Part Number: 2W0181 (Caterpillar reference 2W-0181)
• Type: Folded radiator core - core only, no tanks or frame
• Construction: Folded core, which is a different architecture from the stacked modular cores used on Caterpillar dozers
• Dimensions: 2007 mm x 109 mm
• Material: Alloy copper, alloy brass and alloy mixed metals
• Weight: 45.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces a folded radiator core on Caterpillar 3500 series engines and gen sets, G3512 and G3516 gas engines, and 784 through 793C trucks
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: Core only - end tank seals, gaskets, tanks and hardware are not included. This is a true folded core, not one of the Advanced Modular Cooling System strips found elsewhere in this catalog, and at 109 mm it is the shallowest core stocked. Caterpillar catalogues it against engines, gen sets, marine auxiliaries and mining trucks alike. Ships LTL freight.

Common Use Case or Symptoms:

Fit these when a 3500 series package or a mining truck is losing cooling capacity and the core is past cleaning - a gen set running continuous duty and a haul truck on a long grade put the same steady heat load through this core, and both plug it from the face.

Why Choose Broken Tractor?

• ✅ Copper And Brass Build: Alloy copper with brass, which solders and repairs the traditional way and is why these cores stay serviceable for decades.
• ✅ Engines And Mining Trucks: 3500 series power units, gas engines, gen sets and 785 through 793C trucks on one core - the widest coverage of anything in this section.
• ✅ Shallowest Core Stocked: 109 mm deep, which separates it immediately from the 137 mm and deeper modules elsewhere in the range.
