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.

Frequently asked questions
- Which engines does the Caterpillar 10R-5664 oil cooler fit?
- Distributor listings identify it as the remanufactured lube oil cooler for the Caterpillar 3512B and 3512C diesel engines. Verify against your engine's serial-number arrangement before ordering, as 3500-series oil coolers differ by application.
- Is the 10R-5664 a new or remanufactured part?
- It is a Cat Reman part: a factory-remanufactured oil cooler rebuilt to same-as-new specification and backed by Caterpillar's 12-month Reman parts warranty. It is typically sold with a returnable-core requirement or core deposit.
- Does this part fit gas (G3512) engines?
- No. The corroborated application is the 3512B/3512C diesel platform. Spark-ignited gas variants such as the G3512 are a different engine family and should not be assumed compatible without confirmation.
