Spray some cleaning fluid to start the wiper, and pay attention to whether the wiper movement is smooth and whether there is a loud noise. If so, the wiper may be pressing too hard against the glass and appropriate adjustments must be made. If there are scratches and cannot be wiped clean, it may be necessary to check whether there is aging, cracking, etc., and the wiper blade needs to be replaced.
The most direct way to determine whether the brake pads need to be replaced is to look at the thickness. Generally, the thickness of new brake pads is about 15mm. When only 1/3 (4-5mm) is worn, it should be replaced. Don't wait until the brake pads are worn to the limit and make a "hissing" sound of iron grinding iron before replacing them. At this time, the brake disc may also be damaged.
Like brake pads, frequent emergency braking will increase the loss of the brake disc, so bad driving habits will also directly lead to a reduction in the replacement cycle of the brake disc. The difference is that due to material problems, the brake disc is smaller than the brake disc. The pads are more wear-resistant and the replacement cycle is longer. Under normal circumstances, when the brake pads are replaced 2-3 times, the brake disc needs to be replaced once.
3. Battery
Generally, the service life of Roewe Car batteries is 2-3 years, and the original batteries of new cars can be used for more than 3 years. So if your battery has been used for almost two years, be aware that its service life may have expired. Forgetting to turn off the lights or on-board electrical equipment when getting off the car, not turning off the air conditioner before turning off the vehicle, and using a large amount of electrical equipment without the vehicle, these behaviors will cause damage to the battery.
4. Spark plug
The normal color of the spark plug electrode is off-white. If the electrode is burnt black and has carbon deposits, it means there is a fault. Generally, it should be replaced after driving 20,000-30,000 kilometers. The sign of spark plug replacement is that there is no flashover, or the discharge part of the electrode becomes round due to ablation. In addition, if it is found that the spark plug often deposits carbon and misfires during use, it is usually because the spark plug is too cold and needs to be replaced with a hot spark plug; if there is a hot ignition phenomenon or an impact sound is made in the cylinder, a cold spark plug needs to be used.
5. Tires
The tire replacement cycle is relatively stable among Petrol Car parts. It usually takes about five years. However, during driving, rough road surfaces, unstable tire pressure, or frequent tire punctures will drastically reduce the service life of the tires. , so in addition to checking the tires regularly, trying to maneuver on smooth roads and refusing violent driving are the keys to extending the service life of the tires.
