Is the engine replaced at a 4S store an original one?

[McElla]

Normally, the engines replaced at 4S stores are original. After the claim is confirmed, the dealer places an order with the manufacturer, who then ships an unopened engine. To prevent some individuals from seeking personal gain by swapping the new engine, it's best to be present during the unboxing and assembly, ensuring the engine is in its original packaging and being opened for the first time. For added assurance, you can also inspect certain components of the engine assembly (such as screw threads, sealant, etc.). Impact of engine replacement on the car: A car with a replaced engine will depreciate in value, but there is no exact figure—it depends on the post-replacement usage. Additionally, the reason for replacement is a crucial factor. If it's just a standard engine replacement with no installation or matching errors, there's generally little impact. However, if the engine was replaced due to a traffic accident, the car's market value will likely depreciate significantly, as accident vehicles are generally perceived to have lower safety ratings.
