Back to the ATP Garage guide libraryInternational / MaxxForce 11/13 / Engine identification and parts fitment

Quick answer: For a MaxxForce 11 or MaxxForce 13 parts request, keep the full installed-engine serial, emissions-label information, truck VIN and actual component identity together. Navistar's 2010-engine training identifies the serial on the crankcase and emissions label. Use that engine record alongside the vehicle record, then have the exact replacement confirmed for the installed configuration. [1] [3]

Application: Parts-identification planning using the cited 2010 MaxxForce 11/13 example and a separately labeled 2015 N13 comparison. Their location and prefix details belong to those documents. The EGR section adds separately scoped 2007-emissions valve, 2010-emissions valve/wiring and cooler-repair examples. Confirm the actual engine and current catalog application before using any historical example.

Where should you begin identifying a MaxxForce 11/13?

Navistar's 2010 MaxxForce 11/13 training guide, copyright 2011, says the two engines are externally identical. For that family, it identifies the serial on the crankcase and emissions label. Its introduction associates the first three serial digits 106 with MaxxForce 11 and 125 with MaxxForce 13. [1]

Copy the complete serial, including every letter and number. The three-digit example helps interpret the stated training application; it does not identify a replacement component or decode every later International engine. Have the supplier check the complete engine identity and requested part together.

Use safely accessible labels and existing service records. If the engraving cannot be read, ask the service provider to confirm it. Keep unclear characters marked as uncertain instead of filling them in from a similar truck's number.

Which emissions and build details belong with the serial?

Photograph the entire label clearly enough that the model year, engine family and other identification text can be read where present. Transcribe the details exactly rather than replacing them with a broad description such as “International MaxxForce.” Record the truck's build information separately.

For comparison, Navistar's 2015 N13 overview places that engine's ESN engraving on the upper left crankcase, above the high-pressure fuel pump and below the head. It locates the emissions label on the upper valve cover and lists identity fields including ESN, model year, rating, displacement, engine family and emissions information. This is a 2015 N13 example; use it to understand the importance of the identification record, while obtaining the matching location information for the actual engine. [2]

That document also warns against interchanging the 2015 N13 turbocharger with a 2013 N13 unit and directs the parts catalog. This is a specific N13 example of why the recorded application matters. [2]

Record	Keep with the request	Useful confirmation
Installed engine	Exact model and complete serial.	Does the lookup match the engine currently fitted?
Emissions label	Full readable photograph and its identification fields.	Which engine/emissions application does the catalog use?
Vehicle	Complete VIN, truck model and build record.	Which chassis and feature configuration is recorded?
Replacement history	Engine or assembly replacement invoices and later modifications.	Does the fitted hardware agree with the original vehicle record?
Requested component	Complete markings, label photos and diagnosed component name.	Which current replacement and included items are confirmed?

Why send both the truck VIN and the engine serial?

International's public Service Information overview describes VIN-based parts and service information, with searches by engine, model, vendor and feature code. That supports keeping the vehicle configuration attached to an engine-parts request. The page is a description of the manufacturer's service system, not a public fitment confirmation for a particular product. [3]

If the engine or a major assembly was replaced, include that history. Ask the person performing the lookup to reconcile the original vehicle record with the installed engine and component. Avoid resolving a mismatch by choosing whichever number returns a convenient search result.

A useful response should identify the application used, the requested assembly and any remaining uncertainty. If the only available record is a truck-year estimate or an unreadable label, say so at the start of the inquiry.

Can an electronic data plate help reconcile the record?

Navistar's 2010 MaxxForce 11/13 Data Plate document NAV_DP_021711, copyright 2011, describes stored EDC fields including VIN, vehicle model, engine serial, rating, controller identity and calibration information. Its FAQ says an electronic service tool displays those values and an authorized dealer can correct module information after replacement. [5]

Ask the service provider to preserve the available electronic identification report alongside clear engine-label and component photographs. If the controller record, fitted engine or original vehicle record disagree, report that conflict and the replacement history before the parts lookup. Do not edit a module record to make a proposed part appear to match. This dated data-plate example is an identification aid; it does not confirm a replacement part or authorize a software change.

Why does the exact MaxxForce or N13 application matter?

There is a concrete diagnostic example. IK1201066, revision 5, July 10, 2015, covers 2010-emissions MaxxForce 11/13 cooling diagnostics. Its April 20, 2015 change log removed N13 and directs the N13 diagnostic manual. A similar engine name therefore does not establish that this particular procedure applies. [4]

Apply the same care to the parts inquiry: preserve the engine name, full serial, label and actual hardware instead of treating a broad listing title as the final application check. The cited diagnostic scope does not establish a universal rule about which parts interchange.

Which MaxxForce 11 components need a model-specific check?

For a MaxxForce 11 request, have each proposed component checked against that installed engine rather than accepting a MaxxForce 13 listing by appearance. Keep the complete serial and emissions/build record attached to the turbo or air-control item, EGR assembly or section, fuel-system item, sensor or other diagnosed component.

For each quote, preserve the actual component markings, connections, replacement history and supplied contents. Ask which engine/chassis application the current catalog confirms and which required setup or installation items are included. These are the details to verify; this guide does not claim that every listed category differs between the 11 and 13.

The cited 2010 training identifies two externally identical engines and distinct scoped displacement prefixes. [1] A combined 11/13 training heading establishes the document's coverage, not universal component interchange. Keep the separate N13 example above separate, too.

How should a MaxxForce 11 EGR assembly be identified?

First name the diagnosed item: an EGR valve, wiring/connector repair, cooler core, cooler section or complete assembly. Keep that component identity with the installed engine model, complete serial, emissions record, VIN and existing markings. An "EGR fault" describes a complaint; it does not specify which package should be ordered.

Keep 2007-emissions valve identification separate

IK1200892 revision 2, April 19, 2017, applies to 2007-emissions MaxxForce 11/13. It distinguishes old/new valve styles using actuator-lever construction, the manufacturer label and heat-shield arrangement. It specifically prohibits adjustment of the new-style valve. [6] Have the service provider compare the installed valve with its matching source illustrations; these cues are not a 2010-emissions identification rule or an adjustment recipe.

Preserve the 2010-emissions valve and wiring record

IK1200739 revision 13, August 27, 2014, gives a separate valve-serial identification process for 2010-emissions MaxxForce 11/13, including cases that require both the serial and part marking. Its wiring path also considers a vehicle build before July 1, 2012 and prior pigtail repair history. [7]

Send complete valve-label and connector photographs, the full fault report and relevant repair history. Have the current catalog and diagnostic procedure confirm the valve/gasket generation and any harness item required. The source also lists N13 and MaxxForce 15, with separate exceptions; its combined title does not authorize copying each branch or part to a MaxxForce 11. No old/new valve cross-reference list is reproduced here.

Distinguish an EGR valve from cooler repair scope

IK1201113 revision 13, November 2, 2015, distinguishes the repair of a confirmed internal HT-cooler leak from external housing or joint findings for its stated 2010-emissions MaxxForce 11/13 example. [8] Ask whether the estimate means a core, section, joint repair or complete cooler. Use the coolant-loss and cooler guide for that diagnostic context; the separately listed 2013 N13 repair scope does not make all N13 cooling diagnostics applicable.

What else helps identify the actual replacement part?

Keep the engine-identification record attached to the diagnosed component. A boost complaint, coolant warning or cold-start concern describes an event; the service findings should name the component being quoted.

Copy the complete existing part number and its revision or suffix where shown.
Include clear label and overall assembly photos obtained safely.
State whether the request is for a complete assembly or a related repair item.
Ask about required seals, hardware, connections and any setup or installation requirements.
Request confirmation of the current replacement application and package contents before ordering.

Send the identification record to ATP

Use our part-fitment request with the VIN, full engine serial, component markings and findings. For the diagnostic context, see the 2010-emissions coolant and cooler guide or the cold-start guide. Fitment and availability require confirmation.

Common MaxxForce 11/13 identification questions

Can appearance alone distinguish the 2010 MaxxForce 11 and 13?

The cited training describes them as externally identical. Use the engine-identification record.

Does a 125 serial prefix identify the exact replacement part?

No. The prefix example concerns displacement in the stated 2010 training application. Keep the full serial and component details.

Should a replacement-engine truck use only its original VIN record?

Provide the VIN alongside the installed engine identity and replacement history, then have any mismatch reconciled.

Can I apply the cited 2010 coolant diagnostic to N13?

Its change log specifically removed N13. Obtain the matching current diagnostic information for that engine.

Does an engine-family name in a product title confirm fitment?

No. Ask for the actual application, component identity and required package contents to be confirmed.

Does shared 11/13 training prove the same part fits both?

No. Confirm the exact component and application using the full installed-engine record and current catalog information.

Is an EGR valve the same requested item as a cooler core?

Name the actual diagnosed item and required package. The cited documents distinguish valve identity from cooler core, section and joint repair scope.

Can I use the 2007 valve-style cues for every later MaxxForce?

No. Keep the 2007-emissions identification example separate from the 2010-emissions valve-serial process and its application limits.
