Why is there water in the trunk?

The reasons for water in the trunk are as follows: 1. Poor rainwater drainage around the trunk lid. 2. Insufficient compression force on the sealing strip at certain positions after closing the trunk lid. 3. Deformation or leakage points in the trunk lid. 4. Corrosion of the sealing strip. Solutions for water ingress in the trunk: 1. Drain the water as soon as possible. There is a rubber drain plug at the bottom of the spare tire compartment in the trunk - remove it to drain the water. 2. Quickly locate the leak source. Check if the trunk lid is deformed, inspect the condition of the surrounding rubber seals, or observe light penetration points with the lid closed (mark these spots). 3. Ventilate the trunk. Remove all items and the trunk liner, then leave the lid open for an hour to prevent mold and rust formation.

What are the symptoms of a faulty plain bearing?

Here are the symptoms of a faulty plain bearing: 1. When turning the steering wheel while stationary or at low speeds, a "squeak... squeak" sound may be heard, and in severe cases, vibration in the steering wheel can be felt. 2. When driving on bumpy roads or over speed bumps, a "thud... thud" sound may be heard. 3. Tire noise becomes noticeably louder during driving, and in severe cases, a "hum... hum" sound may be present. 4. The vehicle may pull to one side. Here is a detailed introduction to plain bearings: 1. Plain bearings use high-precision cylindrical rollers (needle rollers) to increase contact length, allowing these bearings to achieve high load capacity and stiffness in a very compact space. 2. DF plain needle roller bearings and plain cylindrical roller bearings feature profiled surfaces on their needle rollers and cylindrical rollers, which reduce edge stress and improve service life.

Where is the windshield washer fluid added in the car?

Windshield washer fluid is typically added to the dedicated washer fluid reservoir in the engine compartment, which has a standardized windshield washer symbol on the cap. The functions of windshield washer fluid include the following points: 1. Anti-freeze function. During winter driving, due to the temperature difference between inside and outside, a lot of frost can accumulate on the windshield, impairing the driver's visibility. Spraying windshield washer fluid can solve this problem because it contains alcohol and other substances that have anti-freeze properties, helping to melt the frost. However, there are different types of windshield washer fluid. If you need anti-freeze functionality, please purchase a proper anti-freeze windshield washer fluid; otherwise, it may not be effective. 2. Anti-fog function. Windshield washer fluid can form a protective film on the glass, preventing fog from forming on the windshield, thus avoiding impaired driver visibility and potential traffic accidents. 3. Lubrication and anti-static function. Windshield washer fluid has a certain lubricating effect, reducing friction between the wiper blades and the glass, thereby extending the lifespan of the wipers and preventing scratches on the glass.

What are the 3 situations of wheel lock-up?

Wheel lock-up can be divided into three situations: skidding, straight-line braking, and sliding. Skidding: When a car brakes sharply at high speed on wet or icy roads, dangerous situations may occur: the rear of the car deviates from the direction of travel during braking, and in severe cases, the car may spin around, losing directional stability. This phenomenon is called skidding. Straight-line braking: During braking, the driver cannot control the direction of the car, meaning the car loses directional controllability. If braking occurs on a curve, the car may slide off the road or into the opposite lane. Even during straight-line braking, the inability to control direction may prevent the driver from avoiding obstacles ahead. Sliding: The movement of the wheels relative to the road surface is no longer rolling but sliding. The lateral friction force and longitudinal braking force exerted by the road surface on the tires become very small. The slipperier the road, the more likely the wheels are to lock up. Additionally, the higher the initial speed of the car during braking, the greater the danger caused by wheel lock-up.

What are the causes of automatic transmission stalling?

Automatic transmission stalling is caused by: 1. Circuit failure, where a short circuit in the low-voltage line causes stalling; 2. Component failure, such as faults in the ignition coil, capacitor, or electronic ignition module; 3. Fuel system failure, including damage to the fuel pump, fuel line rupture, clogged carburetor fuel inlet, or an empty fuel tank. The solutions for automatic transmission stalling are: 1. Turn on the hazard lights; 2. Step on the brake to stop as soon as possible; 3. After stopping, shift the gear lever into the P position and turn the key to restart the engine; 4. Conduct inspection and repair after stalling occurs. The gears in an automatic transmission include: 1. P (Parking gear, starting gear); 2. R (Reverse gear); 3. N (Neutral gear); 4. D (Drive gear); 5. L (Low gear); 6. S (Sport mode); 7. OD (Overdrive gear).
