Technical notes

The 10R-5664 is a Cat Reman lube oil cooler for the 3512B/3512C diesel platform, supplied as a factory-remanufactured assembly rather than a new unit. It serves the engine lubrication circuit, transferring heat from engine oil to jacket water across a tube-bundle/core heat exchanger to hold oil within its operating temperature band under sustained marine and power-generation duty. As a Cat Reman item it is rebuilt to original specification with replaced wear components and is sold on a returnable-core basis, so a serviceable old cooler must be exchanged or a core deposit paid. Distributor listings price the assembly around $3,800 plus a core charge near $2,380. Confirm the unit against the specific engine arrangement/serial number before ordering, since 3500-series oil coolers vary by application.

Compliance

Marine and power-generation engine service component with no standalone regulatory certification; Cat Reman units carry Caterpillar's same-as-new 12-month parts warranty.

Does this part fit gas (G3512) engines?
