Auto oil maintenance is very important，Because it is related to the service life of the vehicle and the personal safety of the passengers。Whether it is lubricant or brake fluid or coolant，Too much or too little is not a good phenomenon。View it clearly，You can remedy it in time，To avoid causing a big mistake to affect driving safety。

Under normal circumstances of brake fluid，The height of the brake fluid is higher than the lowest point，But no need to reach the highest point。Usually, the degree of wear of the number of brake pads of the brake liquid as a corresponding change。If you just replaced the new brake pads, pay attention。Because the new brake pads are thicker，Will overflow the added brake fluid，Notice that the brake fluid droplets have a lot of corrosiveness on the body paint or chassis。If the height of the brake fluid is reduced below the lowest point，It means that you should replace the brake pad。such as seabet mybrake liquid dry，It will lead to a decline in the brake pedal，Slaughter。If the reduction of the brake fluid is not caused by the wear of the brake pads，but caused by leaks，Must be supplemented immediately，and ask the car dealer to repair。Because it is about safety，Do not neglect the meaning。

Steward lubricating oil is generally speaking，As long as the steering device is at the highest point and the lowest point, it is okay。You can also do it by yourself，Special liquid with ATFD2 model，But be sure to pay attention to the same type of liquid of lubricating oil as the automatic transmission，Otherwise, it will be harmful and unhelpful。The lubricant in the steering device will leak a little and it will be obvious，I can understand at a glance when the engine stops running。When the steeringr lubricating oil occurs，The oil pump with filtration effect will dry、Heat，and even worn，Usually accompanied by harsh sounds。In this case，The steering wheel will become very heavy，Although it does not affect the function of steering，But it should be filled with lubricating oil in time，until the steering device becomes relaxed and free。​​But if there is a leak，It is best to ask a car dealer to check，Repair in time。

Under normal circumstances，The position of the oil staying on the ruler should be at the middle of the highest point and the lowest point。When checking the oil，The car must be parked on the horizontal plane，and the engine will be turned off for more than 5 minutes，or wait for the engine to cool。If it is a gasoline engine，Too many oil will erode the cylinder pad。Diesel engine is more dangerous，SeabetMotor oil may be mixed into the cylinder body co -ignition。In this case, even if the throttle is cut off，The engine cannot stop running，On the contrary, it will keep running at a high speed until all the oil consumption is exhausted，The engine is often scrapped! In this situation，To step on the brakes to make the engine run at low speed。Never step on the clutch or stop，That thing will be worse。If the oil is filled too much when the oil is replaced，Let the excess oil be released immediately，Then start again。The oil level is too low、Insufficient oil will cause the engine to increase wear without lubrication。

Under normal condition，The height of the coolant should be between the highest and lowest points，If the color of the coolant becomes darker and turbid，Explain the decline in quality，Need to be replaced。How many coolant is easy to view。But you need to wait for the engine to stop running，After completely cooling down，Because the level of coolant will change during the engine operation，Not easy to be accurate。increased abnormally such as coolant，Reflect that the engine has potential problems。You can discharge excess coolant first，Dowry it to the highest point。Then continue to view。If the coolant continues to rise，It is necessary to find a car dealer to check and repair it immediately。If the level of coolant is reduced to the lowest point，Explain that the engine is short of water，Will warm up。At high temperature，The operation of the engine will cause the cylinder deformation，or the cylinder pad is burned。When replenishing the coolant，It is best to use the same brand product stipulated by seabet loginthe manufacturer。Of course under emergencies，You can also add water。
