Is It Necessary to Break in a New Car?
1 Answers
It is necessary to break in a new car. The engine and other components of a new car are not yet tightly fitted, so applying gentle throttle helps the parts to better align with each other. Excessive throttle may cause excessive wear on some contact surfaces. Precautions during the break-in period: 1. Warm up before starting: After the engine starts, you can begin driving as long as it maintains a stable RPM. Before the coolant temperature rises, control the speed appropriately, and once the temperature normalizes, you can drive normally. During the break-in period, avoid sudden acceleration and hard braking. 2. Avoid high-speed driving: New cars have speed limits during the initial driving phase. Domestic cars are generally limited to 40-70 km/h, while imported cars are usually restricted to 80% of their maximum speed within the first 1,000 km when the throttle is fully open. Drivers should monitor the engine RPM and speed gauges to ensure both operate at moderate levels. The engine RPM during the break-in period should strictly remain between 2,000-4,000 RPM. 3. Avoid overloading: Fully loading a new car can damage its components. Within the first 1,000 km, domestic cars should not exceed 75%-80% of their rated load capacity, and imported cars should not exceed 90%. Additionally, choose smoother road surfaces to minimize excessive vibration, impact, or sudden braking, reducing stress on the body and powertrain. 4. Do not remove the speed limiter prematurely: The speed limiter is a throttle device installed between the carburetor and the intake pipe. Drivers should not remove it early but should wait until after the initial 1,000 km and the first maintenance check. Imported cars usually do not come with a speed limiter, relying entirely on the driver to control the speed.
