Overview – ENGINE OIL COOLER 4012789 Series
The Cummins ENGINE OIL COOLER 4012789 is part of a proven family of components used across Cummins lubrication positions as the oil cooler shedding heat from the engine oil, and several interchangeable part numbers share the same fitment.
Parts Characteristics
An engine oil cooler that sheds heat from the lubricating oil, so the film stays thick enough to protect the bearings under load. It carries the cooling that the oil cannot do alone, so a true, unblocked cooler keeps the viscosity where it needs to be.
Applicable Models & Applications
Used at Cummins lubrication positions specifying this oil cooler (series). Match the core, the porting and the mount against your old cooler – oil coolers differ in how they flow and bolt.
Maintenance & Replacement
Inspect for weep at the cores and restriction at the passages at every oil service. A cooler that has begun to leak drops the level, and the drop is what starves the bearings.
Confirm the flow and the seals on fit so nothing bypasses the core. A cooler run with a split seal passes oil without cooling it, and the oil is what runs hot.
Replace rather than rod a leaking one where the core is spent. A cooler rodded past its life clogs again, and the clog is what cooks the oil.
Keep the correct engine oil cooler for your engine on the shelf. It is load-critical, and an engine stopped on thin hot oil is an engine waiting on a large part.
