What procedures are required for replacing a car engine?

To change the engine number, the vehicle owner must apply for a modification registration with the vehicle management office within ten days after the change. They need to fill out the "Motor Vehicle Modification Registration Application Form," submit the required legal documents and certificates, and have the vehicle inspected. Relevant information about car engines is as follows: 1. Introduction: A car engine is the device that provides power to the vehicle, acting as the heart of the car and determining its performance, fuel efficiency, stability, and environmental friendliness. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Based on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, hybrid engines, and other types.
I just had my engine replaced last year, and this process needs to be done step by step. First, go to the vehicle management office to obtain a vehicle modification certificate, requiring your ID card, vehicle license, and vehicle registration certificate. The engine must be of the same brand and model, and it's best to keep the original purchase receipt. The installation certificate issued by a familiar repair shop was quite important in my case. During the inspection, the police were particularly strict, repeatedly checking the new engine number and chassis number with tracing paper. Luckily, I had the mechanic re-engrave the numbers clearly beforehand. The emission test was even more thorough than the annual inspection—if the exhaust failed, you'd have to remove and replace it again. Finally, it took two working days to get the new vehicle license, and remember to ask your insurance company to update the policy information simultaneously. The whole process took a week, so I recommend booking an inspection slot in advance to avoid long queues.
Last week, I just helped a friend complete the engine replacement procedures. First, you need to find a certified repair shop for the removal and installation, and they must provide a repair certificate and proof of engine origin. Remember to bring the original vehicle owner's ID, the vehicle registration certificate (green book), and the vehicle license, as the DMV will need copies for their records. The most critical part is the vehicle inspection—the stamped serial number on the new engine must match the factory standard. My friend's car had to be reworked because the number was slightly misaligned. The replacement engine must be brand new or a legally sourced used part; smuggled engines will outright fail the inspection. After submitting the documents, keep the acceptance slip—the new vehicle license will be issued within five business days, and the old one will be invalidated with a corner cut off. I recommend letting the repair shop handle the paperwork to save yourself unnecessary trips.
