Tire cracks require replacement under the following conditions: 1. Crack length exceeds 6mm: Cracks shorter than 6mm can be repaired at a service shop. Otherwise, tire replacement is necessary as damage to internal materials cannot be repaired. 2. Numerous small cracks: If the tire shows signs of aging with countless small cracks at the tread groove base or sidewall that are about to reach the carcass, immediate replacement is required. 3. Groove depth: When groove depth falls below 1.6mm, replacement is needed; otherwise, continued use is acceptable. 4. Bulges: Any bulging should prompt immediate tire replacement.

What are the causes of the Ford Focus hatchback's radiator boiling over?

Ford Focus hatchback radiator boiling over can be caused by the following situations: low water level in the radiator, radiator leakage, poor water circulation, or malfunctioning electric fan. You can avoid this issue by the following methods: 1. Replace the coolant before problems arise to eliminate "boiling over" caused by insufficient or deteriorated coolant. 2. Determine whether the water pump and thermostat are functioning properly. Check if the belt connected to the water pump is too loose and whether there is "slippage" in the belt connected to the water pump when the engine starts normally. 3. When the water temperature rises significantly, the electric fan at the front of the engine will automatically rotate to help the radiator dissipate heat better. If the fan does not rotate or fails to operate at high/low speed, check the wiring, fuse, and relay, and repair them accordingly.
