Fitment Note: Trucks may use different turbocharger configurations depending on engine rating, production year and emission-control system. Confirm the original turbocharger number, mounting flange, compressor outlet and actuator arrangement before purchase.
Q1: Does this S300A113 turbocharger fit the E7 12.0L engine?
Yes, it is designed for selected E7 and EM7 12.0L applications using references such as 173526, 631GC5172M3 or 631GC5172AM4. Check the original turbocharger identification plate and engine configuration before ordering.
Q2: What is the difference between 631GC5172M3, M4, M5 and M6?
These numbers represent different service, production or application references for related S300A113 turbochargers. They may correspond to different production revisions or truck configurations. Confirm the complete turbocharger, including the housing, mounting position and air connections, rather than matching only the base model.
Q3: Can this turbocharger be used on both MR and LE trucks?
It may fit selected MR and LE trucks equipped with the same E7/EM7 engine and matching turbocharger reference. The chassis model alone is not sufficient to confirm compatibility, so compare the original part number and turbocharger configuration before purchase.
Q4: What should be checked before installing the replacement turbocharger?
Replace the engine oil and filter, inspect the oil feed and drain lines, clean the intake system and check the charge-air cooler for oil or debris. Prime the turbocharger with clean engine oil before starting the engine, then inspect the intake, exhaust and oil connections for leaks.
