Restore C15 Acert Power: Caterpillar Cylinder Head for MXS/NXS Series

Ruich Value specializes in supplying Heavy Duty Engine Components that keep commercial fleets moving. When downtime costs thousands per day, you need a replacement solution that matches the durability of the original equipment without the dealership markup. Our cylinder head program specifically targets the rigorous demands of the Caterpillar C15 Acert engine family.

The Caterpillar C15 Acert Cylinder Head (OEM 245-4324) is engineered to handle the extreme cylinder pressures and heat cycles typical of Twin Turbo applications. Unlike standard single-turbo heads, this casting features reinforced internal webbing and optimized coolant passages to prevent the common cracking issues found in high-mileage SDP, MXS, and NXS engine serials. Whether you are rebuilding a Kenworth W900 or a Peterbilt 379, this head restores the compression and reliability your rig demands.

Technician’s Note: Installation & Inspection

Technician’s Note: When replacing a C15 Acert head, critically inspect the liner projection (protrusion). Acert engines run significantly higher cylinder pressures than the older 3406E; if liner height is uneven or low, the new head gasket will fail prematurely under boost. We also recommend replacing the bridge hold-down bolts, as they are prone to stretching.

Technical FAQ: Caterpillar C15 Acert Cylinder Head

Does this head fit the Single Turbo C15 (6NZ)?

No, this cylinder head (245-4324) is specifically designed for the Twin Turbo C15 ACERT engines (MXS, NXS, BXS serials). If you have an earlier Single Turbo C15 or 3406E, you likely need part number 110-5096. Please confirm your engine serial prefix before ordering from Ruich Value.

Is the cylinder head supplied loaded with valves?

Standard supply is a “Bare Cylinder Head” (casting with guides and seats installed). However, loaded heads with valves, springs, and rotators can be assembled upon request. Contact our sales team for loaded options.

Do I need new head bolts?

Yes. Caterpillar C15 head bolts are torque-to-yield. Reusing old bolts carries a high risk of snapping or failing to hold the correct clamping force, leading to gasket failure.
