Key Notes:

• Part Number: 1132923 (Caterpillar reference 113-2923)
• Type: Radiator core assembly - core only, no tanks or frame
• Function: Sheds engine heat from the coolant into the airflow through the cooling pack
• Weight: 118.0 lbs.
• Condition: Aftermarket replacement part
• Application: Replaces the radiator core assembly on Caterpillar 330 and 330 L hydraulic excavators, including the A Series variants
• Shipping Restrictions: Ships to the lower 48 US states only
• Note: Core only - tanks, side frames, hoses, cap and hardware are not included. Caterpillar publishes no dimensions, row count or material for this core, so match the unit being removed by size and tube pattern. Ships LTL freight; inspect the fins and tube ends before signing for delivery.

Common Use Case or Symptoms:

Replace this when a 330 will not hold temperature at full hydraulic load, when the core has been rodded out once already and is weeping again, or when the face is bent and packed beyond what a wash will recover - a machine this size makes heat faster than a tired core can lose it.

Why Choose Broken Tractor?

• ✅ Sized For The 330: A core cut for a 330 cooling pack rather than adapted from a smaller excavator, because the heat load here is not the same.
• ✅ A Series Included: Caterpillar covers the 330-A variants under the same number, which is coverage the supplier list alone does not show.
• ✅ Highest Cost Core In The Range: This is the most expensive radiator core in the section, so confirming the part before ordering matters more here than anywhere else in it.
