Caterpillar C13 Cylinder Head 345-3752

Engineered for Endurance: Caterpillar C13 ACERT Cylinder Head

Ruich Value is a specialized manufacturer of Heavy Duty Engine Components for the North American and global trucking markets. The Caterpillar C13 ACERT engine offers a unique balance of weight savings and torque, but its twin-turbo configuration places immense thermal stress on the cylinder head. We provide fleet operators with upgraded aftermarket castings designed to handle these extreme operating conditions better than the original designs.

The Caterpillar C13 Cylinder Head (OEM 345-3752) is the updated casting specification for C13 ACERT applications (commonly KCB and LEE serial prefixes). Unlike early castings that were prone to cracking between the exhaust valves, our 345-3752 replacement utilizes a high-molybdenum alloy iron blend. This material improvement, combined with reinforced mounting bosses for the Variable Valve Actuator (VVA) rails, ensures long-term reliability for your vocational or long-haul truck.

Technical Specifications for C13 ACERT Casting

Technician’s Note: Installation & Inspection

Technician’s Note: The C13 ACERT uses a complex Variable Valve Actuator (VVA) assembly that bolts to the top of the head. When installing this head, it is critical to torque the VVA studs to the exact factory specification. Over-torquing can crack the casting bosses, while under-torquing causes VVA oil pressure loss and engine codes. Also, always inspect the twin-turbo exhaust manifold studs for stretching.

Technical FAQ: Caterpillar C13 Cylinder Head

Does this head fit the C11 engine?

Sometimes. The C11 and C13 share the same block architecture and cylinder head casting in many heavy-duty applications. However, specific valve sizes or injector sleeve configurations may vary. Please verify your casting number matches 345-3752 before ordering for a C11.

Does it include the injector sleeves?

Yes, our 345-3752 cylinder head comes as a bare casting with stainless steel injector sleeves pre-installed and reamed to factory spec. You will need to transfer your valves, springs, and VVA components.

Is this for the “Lee” or “KCB” serial number engines?

This cylinder head is compatible with both KCB and LEE serial number prefixes, which are the most common C13 Acert on-highway configurations. It is the updated replacement for earlier part numbers used on these engines.
