Why does the Baojun 310 occasionally make a grinding noise when starting?

[DeHaven]

If the Baojun 310 occasionally makes a grinding noise when starting, especially during cold starts, it is usually caused by the timing chain lacking lubrication at the moment of ignition, which is a normal phenomenon and does not require repair. Grinding during startup can also be due to a weak battery or starter motor issues. Here are the inspection methods: Timing Belt: Check if the timing belt is broken or has frayed edges. Misalignment: Check if the starter motor is misaligned or if the belt connected to the starter motor is aged or curled. Idle Motor: Inspect the idle motor. It's best to determine if the noise is coming from within the cylinder block. If not, it can generally be confirmed to be related to the car's starting system.
