What is the solution for false high temperature in cars?

False high temperature in cars can be resolved by replacing the thermostat. False high temperature refers to a situation where the coolant temperature is not high, but the gauge indicates a high temperature. The function of the thermostat is to automatically adjust the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. Methods to determine if the thermostat is damaged include: 1. After starting the engine, open the filler cap of the coolant reservoir and observe if there is any water flow inside. If there is no flow, it indicates that the thermostat is damaged or there is debris stuck between the main valve switches. 2. After starting the engine, feel the upper and lower radiator hoses. If their temperatures are the same, it means the thermostat is damaged.

What gear should be used for uphill driving in a Corolla automatic transmission?

You can use the M gear. Reason: Generally, the M gear is used more frequently, and using a lower gear for uphill driving is more reliable; the M gear is a low-speed gear, and using first or second gear is more suitable for uphill driving. Extension: The Corolla automatic transmission has five gears, which are P (Parking gear), R (Reverse gear), N (Neutral gear), D (Drive gear), and M (Manual gear). This car uses a stepped gear arrangement, also known as a serpentine gear arrangement, which is a very common design for automatic transmission gears, often seen in Japanese cars. Its advantages and disadvantages are the opposite of the straight-line arrangement: the advantage is that it is less likely to shift into the wrong gear, while the disadvantage is that the operation is not as smooth and direct as the straight-line arrangement.

What kind of water should be added to the windshield washer reservoir?

Windshield washer reservoir should be filled with automotive-specific windshield washer fluid. The following are the functions of automotive windshield washer fluid: 1. Cleaning performance. The surfactants in automotive windshield washer fluid usually have functions such as wetting, permeation, and solubilization, thereby achieving the effect of cleaning and removing dirt. 2. Anti-freezing performance. The presence of alcohol and ethylene glycol can lower the freezing point of the liquid, thus providing an anti-freezing effect. 3. Anti-fog performance. A single-molecule protective layer will form on the glass surface, ensuring the windshield remains clear and transparent. The following are the steps to add water to the windshield washer reservoir: 1. Open the car's front hood and locate the blue cap behind the left headlight. 2. Find the white tube connected to a white jug-shaped object, with a fan-shaped symbol on the cap indicating the windshield washer. 3. Open the cap and add water directly. If there is not much foam, you can mix in a little dishwashing detergent.

Can the Mazda 3 Axela Add 4 Liters of Engine Oil?

2.0 engine oil adding 5 liters is sufficient, the Mazda 3 Axela can add 4 liters of engine oil. Background of engine oil development: In the mid-19th century, people did not yet recognize the importance of gasoline, and kerosene for lamps was widely used at that time. Petroleum refining then relied on simple distillation processes to separate components with different boiling points from petroleum. Kerosene components have a higher boiling point and were safer to use in lamps, becoming the main product of crude oil refining, while gasoline and other components were often burned as fuel. Carcinogens in engine oil: On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) released a preliminary reference list of carcinogens, with engine exhaust and gasoline listed in the Group 2B carcinogens list.

Reasons Why Tesla Phone Key Fails to Detect

No need to point the key at the Model-S, but it must be within the detection range (this depends on the strength of the key battery). The specific details are as follows: 1. If the Model-S cannot detect the key, the touchscreen will display a message indicating that the key is out of range. Place the key in a position where the Model-S can effectively detect it. Radio frequency devices with similar frequencies near the 12V power socket may interfere with the key. 2. If this happens, move the key at least 30cm away from other electronic devices (such as mobile phones, laptops, etc.). If the key still doesn't work, the battery may need to be replaced. It's important to note that the Tesla Model-3 features a keyless design, and the provided card key can also unlock the car doors.

Is the Cayenne wheel hub cast or forged?

21-inch wheels are forged, and they must be forged. Wheels below 20 inches are cast. Comparison between forging and casting: Forging is better. Forged wheels are stronger and lighter than cast ones. Not just for wheels, but generally for structural components, forged parts are more expensive than cast ones, and of course, their quality is also superior. Seat design: The 2021 Porsche Cayenne features sport-style seats with raised sides, integrated headrests, and a racing bucket seat design that not only offers strong visual appeal but also provides electric adjustment for leg and lumbar support in the front seats, along with ample space for both the driver and passengers.
