Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

• ALFA-ROMEO > ALFA-ROMEO 147 156 1 9 JTD > FIAT M737AT 19Z EURO 4

This GT1749V turbocharger is listed for Alfa Romeo 147 and 156 models equipped with the 1.9 JTD engine. The application path references the Fiat M737AT 19Z Euro 4 engine code. Buyers should verify fitment by matching the 777251-5001S part number against their specific vehicle VIN and engine details. Cross-reference numbers such as 55188690, 55205177, and 71724094 serve as reference points to confirm the correct replacement application. Treat these application clues as verification aids rather than confirmed fitment. Always check the original turbocharger markings on the vehicle to ensure the correct model and configuration before ordering.
