Technical notes
The 7W-5455 is the bar-type aftercooler (charge-air cooler) core for Caterpillar 3500-series engines, including the 3512B marine application as well as the 3508/3516 family. It sits in the aftercooler housing between the turbocharger and intake manifold, cooling pressurized intake air to raise charge density and lower combustion temperatures. It is the alternate/bar-type version of the core; distributors also list a companion core (7W-5456) and related 8N-4793, so confirm the specific aftercooler group, fins-per-inch count, and jacket-water vs. separate-circuit cooling arrangement against your engine's serial-number breakdown before ordering. Reported dimensions are roughly 246 x 1475 x 166 mm. Verify port orientation and tank/gasket compatibility, since 3500-series aftercooler configurations vary by build and rating.

Frequently asked questions
- Does the 7W-5455 aftercooler core fit the Caterpillar 3512B marine engine?
- Yes. Distributor listings show 7W-5455 fitting the 3512B along with 3512 and 3516 (3500/3508 family). Because 3500-series aftercooler configurations vary by serial number and rating, confirm the specific aftercooler group and core before ordering.
- Is 7W-5455 the same as 7W-5456 or 8N-4793?
- No. 7W-5455 is the bar-type core; 7W-5456 and 8N-4793 are related but separate part numbers within the 3500-series aftercooler assembly. Match the exact Caterpillar number to your engine's parts breakdown rather than substituting.
