2949052 294-9052 Radiator Kit CAT 3512 3516 3406 Excavator Engine Cooling Parts

The 2949052 radiator kit is a complete cooling assembly prepared for CAT 3512, 3516 and 3406 diesel engines. It is the number our workshop customers reach for when a machine has been running hot, when a core has been punctured by debris, or when an engine is out of the frame for a scheduled overhaul and the cooling side is being renewed at the same time as the internals. The kit is supplied as 2949052 and carried as 294-9052, and it arrives with the radiator core, upper and lower header tanks, side frames, mounting brackets, rubber isolators and connecting hardware already matched as one set, so a shop does not have to chase individual components across several suppliers while a machine sits idle.

Where the original mounting detail is worn or cracked, the same order is normally combined with 4N-3311, which we also list as 4N3311. The two references belong together in most 3512, 3516 and 3406 rebuild plans: the radiator kit handles heat rejection, and the mounting set covers the support and bracket detail that rarely survives several thousand hours of vibration in an excavator frame. Supplying both under one part number family keeps fitment consistent and avoids the mismatch that appears when a substitute bracket is bolted to an original core.

Part Numbers Behind the 294-9052 Radiator Kit

Cooling assemblies for this engine group are quoted in several writing styles, and the way a purchasing system stores a reference is often not the way a workshop writes it on a job card. We supply the radiator assembly as 2949052 and as 294-9052, and we pair it with 4N-3311 and 4N3311 for the mounting side of the same job, so an enquiry typed in either style reaches the correct kit on the first attempt. The wider cooling group follows the same double listing: the 295-5458 radiator kit used on 3508, 3512 and 3516 engines is also written as 2955458, the 376-4216 water pump for C13 units is listed as 3764216, the 377-3016 thermostat for C9.3 engines is listed as 3773016, the 497-3990 thermostat assembly for C7.1 machines is listed as 4973990, the 9Y-3333 heat exchanger core for 3304 and 3306 engines is listed as 9Y3333, the 296-8388 impeller for C12, C15, C18 and 3406E engines is listed as 2968388, and the 472-7445 oil cooler base for C13 applications is listed as 4727445.

Cooling and Air Side Ordered With the Kit

A radiator replacement rarely stops at the core. Filters are normally added to the same sheet: the 4P-5500 filter set for 3508, 3512 and 3516 engines alongside its 4P5500 equivalent, the 1R-0726 oil filter with the 1R0726 reference, the 243-6350 air filter or 2436350 unit for C9 machines, the 106-3969 air filter and 1063969 counterpart for C15 and C18 engines, and the 326-1644 fuel water separator or 3261644 separator for 3406B installations. Mounting hardware and sealing items travel with them, covered by the 520-7951 screw bolt and 5207951 equivalent for 3512 assemblies, the 227-1204 gasket or 2271204 gasket for C15, C18 and 3406 engines, and the 2W-0494 rear idler gear plus 2W0494 reference where the front gear train is being refreshed at the same time.

Engine Parts Ordered Alongside the Cooling Work

Once the cooling side is opened up, the mechanical list usually follows. Fuel side demand centres on the 236-0962 injector and 2360962 equivalent for C-9 units, the 557-7627 injector or 5577627 unit for C7 and C9 engines, and the 326-4635 pump head with its 3264635 counterpart for 320D and 323D machines. Internal parts are covered by the 574-9895 piston ring kit and 5749895 equivalent for C7.1, the 391-3732 piston kit or 3913732 kit for the same family, the 341-8888 valve push rod and 3418888 rod for C10, C12, 3176C and 3196 engines, and the 7E-2464 valve seal set or 7E2464 set for 3306, 3406 and 3304 engines. On the control side, machines that share a harness with the 3412 installation are quoted with the 348-2387 module or 3482387 equivalent, the 320-3060 pressure sensor and 3203060 reference, the 201-1283 harness assembly with 2011283, and the 134-0670 control device or 1340670 unit used on C15, C18 and 3512 arrangements.

Typical Applications

• 3512 engines - mining haul trucks, continuous power generator sets and marine propulsion support where sustained load demands stable coolant temperature.
• 3516 engines - large excavators, heavy generator sets, dredging and offshore support equipment operating in high-hour duty cycles.
• 3406 engines - wheel loaders, dozers, excavators and industrial power units in quarry, construction and agricultural fleets.

Stock Planning Advice

Workshops supporting a mixed fleet of 3512, 3516 and 3406 engines normally keep one radiator kit as a changeover unit and rotate the failed core into a rebuild line, which shortens the time a machine spends waiting for parts. Because 2949052 and 294-9052 cover the same assembly, a single set on the shelf protects several machines, and holding 4N-3311 alongside it covers the support parts most often found worn at the same service interval. Distributors serving several workshops in one region often order in multiples of three or five sets so that a stock-out does not appear during the rainy season, when access to mining and construction sites becomes slow.
