Do new cars need a break-in period nowadays?

New cars definitely require a break-in period. Even for the same model with identical manufacturing processes, standards, and components, each vehicle will still have assembly variations when exposed to different environments, times, and temperatures. Therefore, manufacturing and assembly tolerances are unavoidable. The break-in process for new cars aims to minimize discrepancies between moving parts and bring the vehicle to its optimal operating condition. Here's relevant information: 1. Speed during break-in: Generally, it's recommended not to exceed 80 km/h for the first 500 km, 100 km/h at 1,000 km mileage, and 120 km/h between 1,000-1,500 km. This facilitates proper engine break-in. 2. Engine RPM: The engine break-in isn't solely related to speed but also involves RPM. Typically, maintaining engine speed between 2,000-4,000 RPM during break-in is most appropriate. Consistently driving at extremely low speeds or undertaking long-distance high-speed journeys during break-in doesn't benefit the process and may even cause component stress cracks or other detrimental conditions.

How to Call the Owner to Move the Car When It's Blocked?

When your vehicle is blocked by another car, you can notify the owner through the following methods: 1. Call the 114 hotline: You need to provide your license plate number and phone number to 114, along with the other party's license plate number. 114 will notify the owner to move the car via text message or phone call. 2. Call 122 or 110: Dial 122 or 110 to seek assistance from the traffic-specific hotline. Inform them of the situation, and the traffic hotline will contact the owner. 3. Use the One-Click Move Car feature: The One-Click Move Car feature is a convenient service introduced by the 12123 traffic management department. When you need to move a car, using this feature will automatically compare the vehicle information in the database. The system will then query and retrieve the owner's phone number in the background and send a move car notification via SMS or app push message.

Does the 2021 Corolla come with a particulate filter?

2021 Corolla models do not come with a particulate filter. The 2021 Corolla has a total of 12 variants, none of which include a particulate filter, yet they still meet the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they are released into the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. Inside the filter, densely arranged bag-style filters capture the carbon particles on a metal fiber felt filter. When the accumulated particulate matter reaches a certain level, a burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the 2021 Corolla has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe for an additional cylindrical section. If present, that is the particulate filter.

Is It Necessary to Replace the CV Joint If It's Leaking Oil?

CV joint leakage requires replacement. The primary reason for CV joint oil leakage is the damage to the external rubber boot, which leads to insufficient lubrication of the CV joint, causing severe wear and damage. It is recommended to replace it to avoid major losses due to minor issues. CV joints can be divided into three types: outer CV joint, inner CV joint (tripod type), and inner CV joint (six-ball type). The specific descriptions are as follows: 1. Outer CV Joint: In this type of CV joint, the steel balls are fixed in six windows of a cage between the inner race and the outer race. The steel balls are positioned exactly halfway in both the inner race and the outer race to determine the angle of the universal joint. The smooth surface treatment allows the movement of the universal joint to function like a helical gear. The six steel balls each push their respective ball tracks in the inner race and outer race, transmitting torque through the steel balls instead of gear teeth. 2. Inner CV Joint (Tripod Type): The tripod-type constant velocity joint does not have steel balls but uses three bearings with needle rollers that can slide within three tracks in the outer race. It is mainly used for the inner CV joint of four-wheel-drive vehicles, suitable for positions where the torsion angle is not large. It can slide inward and outward to accommodate the length changes of the drive shaft during vehicle movement. 3. Inner CV Joint (Six-Ball Type): This sliding-type constant velocity joint product has a different design concept, where torque is transmitted by steel balls in inclined tracks. The product performs exceptionally well, surpassing the TJ-type inner CV joint, but has a shorter sliding distance, which can address noise issues. It is widely used in four-wheel-drive vehicles.

What to Do If There Are Small Bubbles After Applying the Film?

Depending on the number and size of the bubbles, you can either replace the film or smooth them out. Below are some solutions for dealing with small bubbles after applying the film: 1. Many large bubbles: If there are numerous large bubbles that are difficult to smooth out, it is recommended to replace the film entirely, as this not only affects aesthetics but also driving safety. 2. Few but large bubbles: If there are not many bubbles but they are large, you can make a small cut and use a squeegee and a heat gun to slowly smooth them out. 3. Few and small bubbles: If there are only a few small bubbles, you can puncture them with a needle and then press them flat. 4. Sudden occurrence of many large bubbles: If bubbles suddenly appear in large numbers and are big enough to affect driving safety, you can gently lift the edge where the bubbles are, similar to applying a phone screen protector, and then reapply the film following the proper procedure. However, this method is only suitable for emergencies, and it is recommended to replace the film as soon as possible afterward.
