How to Remove Stubborn Water Stains from a Car?

What are the reasons for the starter not working?

The reasons for the starter not working are: 1. Insufficient battery charge; 2. Loose or detached starter terminals, switch or solenoid failure; 3. Worn brushes or improper brush alignment, weak springs; 4. Short circuit or open circuit in the field coil or armature coil; 5. Dirty commutator or protruding mica causing poor brush-to-commutator contact. The solutions for a non-working starter are: 1. Charge or replace the battery; 2. Clean the wiring and tighten the terminals; 3. Clean the brush surface or replace the brushes; 4. Repair or replace the assembly; 5. Replace with the recommended suitable engine oil. Precautions for starter use include: 1. Shift the transmission into neutral before starting; 2. Do not operate the starter for more than 5 seconds at a time, with intervals of at least 15 seconds between attempts; 3. Immediately release the ignition switch after the engine starts to cut off the starter and stop its operation; 4. Turn the key back immediately after the engine starts to allow the starter's drive pinion to disengage promptly.

How many kilometers is the break-in period for the Volkswagen CC?

The break-in period for the Volkswagen CC is 5,000 kilometers, which is before the first free maintenance service. Precautions during the break-in period: 1. Avoid emergency braking: During the break-in period, avoid emergency braking, do not exceed a speed of 120 km/h, and avoid full load. 2. Avoid driving in N gear: During daily driving, use a variety of throttle positions to allow the transmission to shift more frequently. During both the break-in period and normal use, try to avoid driving in N gear as it can damage the transmission. This is because in N gear, the lubrication of the transmission oil is at its worst and is unsuitable for high-speed operation. 3. Keep speed below 120 km/h: During the break-in period, do not exceed 120 km/h on the highway. After the break-in period, it is advisable to drive at higher speeds occasionally to help burn off carbon deposits in the cylinders. Occasionally accelerating hard can also be beneficial for the car.

Why Does the Newly Replaced Brake Pads Make Noise at Low Speed?

Brake pad noise can affect normal driving. The reasons and solutions for noise from newly replaced brake pads are as follows: 1. Noise occurs when braking, but not when not braking: This situation is caused by the wear between the brake pads and the brake disc. After prolonged use, the old brake pads and brake disc have formed a certain complementary shape. When new brake pads are installed, the edges of the brake pads may not make even contact with the brake disc, leading to friction and noise. 2. Issues with brake pad material: If non-standard brake pads are used, the larger particles in the material can easily cause noise during braking. 3. Solutions: For the first situation, the edges of the brake pads need to be smoothed to ensure no friction occurs between the brake pads and the brake disc, thus eliminating the noise. If this doesn't work well, a brake disc repair machine can be used to grind and polish the brake disc to solve the problem. For quality issues, it is necessary to replace them with good-quality brake pads.

What does the tire pressure warning light on the Roewe 360 mean?

Here are the specific reasons why the tire pressure warning light on the Roewe 360 may illuminate: 1. Punctured tire: You can use a tire pressure gauge to measure the pressure. The normal values are 2.3 for the front tires and 2.5 for the rear tires. If the pressure is low, inflate the tires and then observe the tire pressure warning light. 2. Excessive tire pressure: The standard tire pressure is 2.4-2.5bar; for reinforced tires, it is 2.8-2.9bar. The maximum pressure should not exceed 3.5bar. Therefore, if any tire exceeds 3.0bar, it will trigger the tire pressure monitoring light. 3. Low tire pressure: When the pressure drops below 1.8bar, it will cause the tire pressure monitoring light to illuminate. Regular checks should be performed to ensure the tire pressure monitor is functioning properly. If the tire pressure monitor does not alert you promptly when an issue arises, it may indicate a problem with the monitor itself.

How to Judge Distance When Turning a Car?

Here is the relevant introduction on judging distance when turning a car: 1. Judging the following distance: When you see the upper edge of the front car's bumper from the lower edge of the windshield, it is about 1m; when you see the lower edge of the front car's bumper from the lower edge of the windshield, it is about 2m; when you see the lower edge of the front car's rear tire from the lower edge of the windshield, it is about 3m. The horizontal line relative to the ground seen from the lower edge of the left rearview mirror is the position of your own car's front. 2. Judging the left and right distance: Adjust the left rearview mirror so that your own car occupies 1/4 of the position, and the upper and lower parts each occupy half, so that both the trunk and the road conditions can be taken into account. Adjust the right rearview mirror similarly so that your own car occupies 1/4 of the position, but the upper and lower ratio is 1:4. For the interior rearview mirror adjustment, first adjust the sitting posture, and then make the upper and lower parts each occupy 1/2, so that basically the rear view can be clearly seen.

Original Spark Plug Model for Classic Focus

Classic Focus spark plug model is TR6F13. What does a spark plug consist of: A spark plug mainly consists of terminal nut, insulator, terminal stud, center electrode, side electrode and shell. What types of spark plugs are there: Main types of spark plugs include: standard spark plug, extended insulator spark plug, electrode spark plug, seat spark plug, pole spark plug, surface gap spark plug. How does a spark plug work: Under high voltage, the air between the center electrode and side electrode of the spark plug will rapidly ionize, forming positive ions and negative free electrons. When the voltage between electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulation property. A discharge channel forms in the gap, resulting in "breakdown" phenomenon. At this moment, the gas forms a luminous body, namely "spark". Along with thermal expansion, a "snapping" sound also occurs. The temperature of this electric spark can reach 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the combustion chamber.
