How Long Does an Overhauled Engine Last?
1 Answers
An overhauled engine typically lasts between 5 to 10 years. Engine overhaul refers to the comprehensive restorative repair process for new vehicles or previously overhauled cars after they have traveled a certain mileage or time period. This involves diagnosis, technical evaluation, and the repair or replacement of automotive components to fully or nearly fully restore the vehicle's technical performance. Precautions after an engine overhaul include: 1. Avoid high engine speeds—do not exceed 3,000 RPM; 2. Allow a warm-up period after a cold start, waiting for the coolant temperature to change before driving, usually about 5 minutes; 3. Adhere to the vehicle's load capacity specifications and avoid exceeding 70% of the maximum load; 4. Minimize sudden acceleration and hard braking, as these actions can cause significant impact damage to the new engine, especially during sudden acceleration, which severely affects the break-in of new engine components and directly impacts the fit clearance between parts; 5. Anticipate and handle unexpected situations early by maintaining steady speeds and avoiding prolonged low-speed driving. Pay attention to gear changes and avoid staying in a single gear for too long; 6. It is recommended to change the engine oil as soon as the break-in period is completed.
