Can a car be fitted with a second-hand engine?
1 Answers
It is possible to replace a car's engine with a second-hand one. As long as the replacement engine comes with the corresponding certification, the replacement can be carried out. However, a technical modification application is required, and only the original manufacturer's engine model can be used. Precautions for replacing a second-hand engine: It is necessary to check whether the water pump fan belt is properly tightened. The belt should not be overly tight. An excessively tight belt can cause it to stretch or break, shortening its lifespan, and may also lead to deformation or bending of the generator shaft, water pump shaft, and premature bearing damage due to excessive tension. The tension of the car engine fan belt should comply with technical requirements, generally with a deflection of 10 to 15 mm during normal assembly. Replacement regulations: Within ten days, the vehicle owner must directly apply for a modification registration with the vehicle management office. Required documents include the engine certification, maintenance list, proof from the maintenance unit, and invoice. Additional documents such as the registration certificate, vehicle license, and owner's ID card are also needed. The registration certificate will be updated accordingly, and a new vehicle license will be issued. Some regions may also require inspection of the old engine. In the case of a free replacement, a proof of the reason for the free replacement must be provided (in the absence of an invoice). After completing all modification procedures, the vehicle insurance information must also be updated.
