Part Number: 4P0251 (Caterpillar reference 4P-0251)
Type: Oil cooler core assembly - core only, no tanks or frame
Function: Holds hydraulic and transmission oil at working temperature, separate from the engine coolant circuit
Material: Carbon, alloy and structural steel - no copper in the build
Weight: 53.0 lbs.
Condition: Aftermarket replacement part
Application: Replaces the oil cooler core on Caterpillar 950F, 950F II and 960F wheel loaders
Shipping Restrictions: Ships to the lower 48 US states only
Note: This is the OIL COOLER core, not the radiator core. Caterpillar catalogues a separate engine radiator core, 4P-0893, against these same three loaders - if the complaint is coolant temperature rather than oil temperature, that is the part you want. Tanks, seals, lines and hardware are not included. Caterpillar publishes no dimensions for this core; measure before ordering. Ships LTL freight.
Common Use Case or Symptoms:
Order this when hydraulic or transmission oil temperature climbs late in a shift, when the loader goes slow and hot after an hour of load-and-carry, or when the cooler is seeping oil onto the rear frame - oil heat and coolant heat are separate problems on these machines and get fixed with separate parts.
Why Choose Broken Tractor?
✅ Oil Circuit Not Coolant: This core carries oil, not engine coolant - a distinction worth getting right before a part is ordered, because both cores fit the same three loaders.
✅ All Steel Construction: Carbon, alloy and structural steel with no copper, which is how Caterpillar builds an oil cooler core to take the pressure.
✅ Three F Series Loaders: 950F, 950F II and 960F share the same core.
