Here are the specific reasons for abnormal noise after replacing brake pads: 1. The old brake disc was not resurfaced when installing new brake pads, resulting in improper fit. Improper fit or installing new pads on an unresurfaced old disc will cause the new pads to rub directly against the uneven surface of the old disc, ultimately leading to uneven wear of the new brake pads. 2. There may be defects in the brake system itself, causing the brake pads to only partially contact the brake disc. This increases the pressure per unit area during braking, resulting in abnormal noise. It is recommended to check components such as the caliper and guide pins. 3. Foreign objects may be present, causing the contact surfaces to not fit properly, resulting in abnormal noise.

How to Clean Resin Oil?

Specialized asphalt-removing car wash liquid can be used to clean resin from a car. It has a mild and neutral nature, capable of quickly and effectively removing tar, asphalt, resin, and other adhesive substances from the paint surface. If the resin on the car body is not severe, hot water with a small amount of laundry detergent can be used, along with a brush to scrub off the resin. Here is additional information about resin oil: 1. Epoxy resin oil is a sticky, gray-black substance, typically used as a coating for cars. 2. Its main components include: essential oils, spicy ingredients, pigments, resin, and some non-volatile oils and nucleic acid compounds. 3. It easily sticks to cars or clothing. The cleaning method for epoxy resin oil requires dissolving its synthetic components. When a car is stained with epoxy resin oil, asphalt remover or adhesive remover and other cleaning agents can be used for cleaning.

What does 5w30 mean for engine oil?

Engine oil 5w30 is a multi-grade viscosity. Here is the relevant introduction of engine oil 5w30: 1. The number 5 represents the ability to withstand external low temperatures of -30 degrees Celsius, and the smaller the number, the lower the ambient temperature it can be used in; 2. The number 30 represents the kinematic viscosity standard of 30 at 100 degrees Celsius, and this number indicates the oil's high-temperature resistance index. The larger the value, the better the protective performance of the oil at high temperatures. Here is the introduction to the role of engine oil: 1. It separates the surfaces of relatively sliding parts, thereby reducing wear; 2. It brings heat back to the oil tank and then dissipates it into the air to help the radiator cool the engine; 3. It circulates carbon deposits, sludge, and worn metal particles on engine parts back to the oil tank, flushing away dirt generated on the working surfaces of parts through the flow of the lubricating oil.

Will the particulate filter of the Tayron 330 get clogged if frequently driven on highways?

The particulate filter of the Tayron 330 can get clogged when frequently driven on highways. Relevant details are as follows: 1. Clogging of the particulate filter: This directly results in reduced vehicle acceleration and increased fuel consumption. 2. Introduction to the particulate filter: Abbreviated as GPF, its function is to filter tiny particles from exhaust gases. When a certain accumulation is reached, it automatically burns the captured particles to continue the cycle. Since the implementation of the China VI emission standards, the Tayron has been equipped with GPF to meet emission requirements. 3. Solutions: It is recommended that owners frequently drive on highways, maintaining speeds above 80 km/h. Alternatively, they can rev the engine at a standstill at a 4S shop to help regenerate the particulate filter. However, these methods do not completely resolve the issue, as it is a design flaw.

Can the car start without the key?

If you don't have the car key, the car won't start. For cars that require turning a key to start the engine, the car cannot be started without the key. Similarly, for cars equipped with a push-button start system, the car also cannot be started without the key. Here are the relevant details: 1. For cars equipped with a push-button start system, the driver must bring the car key into the vehicle to start it. If the car has a push-button start system, there is a receiver module on the car body and a transmitter module in the key. Only then can the engine be started by pressing the start button after entering the car. 2. If the car key's battery is dead, the engine can still be started. Cars with a push-button start system have a designated key-sensing area inside the vehicle. If the key's battery is dead, place the key in this designated area to start the engine.
