PACCAR MX-13 EPA13 Cylinder Head – 2190203PE

Replace a damaged or failed cylinder head with this PACCAR MX-13 EPA13 cylinder head, identified by part number 2190203PE. It is intended for compatible PACCAR MX-13 diesel engine applications and cross-references several earlier and related PACCAR cylinder head numbers.

Because PACCAR MX-13 cylinder heads can vary by engine generation, emissions configuration, casting, and serial number, fitment should be confirmed before ordering. Provide your engine serial number and current cylinder head or casting number to Heavy Duty Kits so our parts team can help verify compatibility.

Part Numbers and Cross-References

This PACCAR MX-13 EPA13 cylinder head is associated with the following reference numbers: 1904700, 1904700R, 2115424R, 2115424PE, 2115424PEX, 2128155R, 2128155PE, 2128155PEX, 2146346, 2146346R, 2146346PE, 2146346PEX, 2184938R, 2184938PE, 2184938PEX, 2190203, 2190203R, 2190203RN, 2190203PE, and 2190203PEX.

Cross-reference numbers are supplied as an identification aid. A matching number alone does not guarantee fitment because production changes and engine-specific configurations may apply. Always confirm the replacement using the engine serial number, original part number, casting number, and vehicle application.

When Should a PACCAR MX-13 Cylinder Head Be Replaced?

A cylinder head may require replacement when inspection identifies cracking, damage to the sealing surface, internal coolant or oil leakage, damaged valve or injector areas, or another condition that prevents the head from being reused safely. Common warning signs may include coolant loss, overheating, abnormal exhaust smoke, combustion pressure entering the cooling system, loss of compression, or coolant and oil contamination.

These symptoms can also be caused by other engine components. The cylinder head should be inspected and the root cause of the failure identified before replacement. Correct diagnosis helps prevent damage to the replacement head and reduces the risk of repeated engine failure.

Fitment Verification Before Ordering

To verify whether part number 2190203PE is correct for your PACCAR MX-13 engine, have the following information available:

• PACCAR engine serial number
• Vehicle year, make, and model
• Current cylinder head part number
• Casting number, when available
• EPA or emissions generation
• Clear photographs of the existing cylinder head and identification labels

Do not select an MX-13 cylinder head only by the truck model or advertised engine family. Confirming the complete engine information is especially important when dealing with superseded part numbers or engines that have previously been repaired or replaced.

Installation Recommendations

Installation should be completed by a qualified heavy-duty diesel technician following the current PACCAR service procedures for the specific engine serial number. Before assembly, inspect the engine block, liner protrusion, cooling system, lubrication system, injectors, fasteners, and related sealing surfaces.

Use the correct head gasket and required installation components for the verified engine configuration. Follow the manufacturer’s prescribed tightening sequence, torque procedure, cleanliness requirements, and fluid specifications. The underlying cause of the original cylinder head failure should be corrected before the engine returns to service.

What Is Included?

The exact cylinder head configuration and included components should be confirmed before purchase. Contact Heavy Duty Kits to verify whether the supplied unit is bare, assembled, or loaded and whether valves, springs, injector tubes, camshaft components, gaskets, mounting hardware, or other installation parts are included.

Frequently Asked Questions

What engine does cylinder head 2190203PE fit?

Part number 2190203PE is listed for compatible PACCAR MX-13 EPA13 diesel engine applications. Final compatibility must be checked using the engine serial number and original cylinder head information.

Does 2190203PE replace 1904700 and 2146346?

The product is cross-referenced with 1904700, 2146346, and several related PACCAR numbers. Because supersessions and configurations can vary, contact the Heavy Duty Kits parts team to confirm the correct replacement for your particular engine.

Is this PACCAR MX-13 cylinder head new or remanufactured?

Confirm the product condition with Heavy Duty Kits before ordering. The condition, included components, warranty terms, and any core requirements should be documented on the order.

No. The truck year alone is not enough for reliable cylinder head identification. The engine serial number, EPA generation, original part number, and casting information should also be checked.

How is the MX-13 cylinder head shipped?

This is a heavy engine component that ships by LTL freight. Confirm the delivery address, unloading requirements, freight charges, and inspection procedure before shipment.
