Caterpillar publishes no replacement or superseding number for 141-5975.
Broken Tractor also stocks the complete 325B radiator under 1099516 (Caterpillar 109-9516) for the 322B L, 325B and 325B L. That is the whole radiator; this number is the core alone.
Key Notes:
Part Number: 1415975 (Caterpillar reference 141-5975)
Type: Engine radiator core - core only, no tanks or frame
Function: Circulates coolant through finned tubes and channels air across them to hold engine temperature
Weight: 115.0 lbs.
Condition: Aftermarket replacement part
Application: Replaces the engine radiator core on Caterpillar 322B and 325B series hydraulic excavators
Shipping Restrictions: Ships to the lower 48 US states only
Note: Core only - tanks, side frames, hoses, cap and mounting hardware are not included, and the tanks are normally transferred from the old unit by a radiator shop. Caterpillar publishes 134 lbs for this core against the supplier's 115 lbs, so the shipped weight may be higher than shown. Ships LTL freight; inspect on arrival.
Common Use Case or Symptoms:
Fit this when a 322B or 325B loses cooling capacity under load - a core that has lost a third of its fins still looks intact from the walkway but will not hold temperature on a hot day with the boom working, and pressure testing is the only way to be sure.
Why Choose Broken Tractor?
✅ Core Or Whole Radiator: The complete radiator for these machines is stocked separately, so a shop with tank capability and one without can both be served.
✅ Four B Series Variants: Covers the 322B L and LN alongside the 325B L and LN on one core.
✅ Freight Weight Flagged: The OEM weight runs 19 lbs above the supplier figure, and knowing that before booking a freight quote is worth something.
