Description:
PP-246-2389 Caterpillar Oil Cooler
This Seakamp Oil Cooler is a marine-grade replacement designed for Caterpillar marine diesel engines used in commercial workboats and yachts, most commonly fitted to the C12 family. The unit has a 4" x 12" core.
The oil cooler routes engine lubricating oil through a tube-and-shell heat exchanger where raw water (or, in some applications, engine coolant) absorbs heat from the oil before it returns to the engine's lubrication circuit. Maintaining stable oil temperature is essential for consistent viscosity, oil-film integrity and component wear protection.
Oil that runs too hot loses viscosity and protective film strength, accelerating wear on bearings, camshafts and turbocharger shafts. A correctly functioning oil cooler keeps oil in its design temperature band, extending oil service life and protecting the engine's most expensive internal components.
Manufactured to match OEM dimensions, port orientation and mounting geometry, the 246-2389 is a true direct-fit replacement for the original Caterpillar component. It installs without modification to existing hoses, brackets or pipework, making it suitable for planned maintenance, corrosion replacement or preventative servicing.
