A car can be turned off without shifting to P gear, but it may damage the transmission and engine. It is recommended to shift to P gear before parking and turning off the engine. The P gear mechanically locks the output shaft of the transmission to secure the car, preventing it from moving. If the car is turned off without shifting to P gear on uneven ground, it may move slightly. This happens because the P gear transmission has a locking mechanism that engages with the transmission gears. Any movement at this point can cause impact to the transmission gears, leading to slight forward movement of the car. The P gear is a common gear in automatic transmission vehicles, usually located at the frontmost position of the gear shift console, ahead of the R gear, designed to lock the axle and keep the car stationary on slopes.

You can actually turn off the car without shifting to P gear, which I've learned from years of driving experience. Theoretically, the engine will stop, and the car can be shut down, but it just doesn't feel right when operating. For example, if you turn off the car in other gears, the vehicle might shake slightly, and the transmission could suffer impact. Once, I was in a hurry and turned off the car without shifting to P gear—the car shook violently, warning lights came on, and it gave me quite a scare. Doing this long-term can accelerate gear wear, and repairs can be costly. Most importantly, there's a safety risk: if parked on a slope without locking, the car could roll and cause an accident. Developing a good habit is simple—after stopping, firmly press the brake to stabilize the car, then shift to P gear, pull the handbrake tight, and finally turn off the engine. Don’t cut corners—details determine driving safety.

What Causes the Car Fan Not to Rotate?

Here are the specific reasons why a car fan may not rotate: The water temperature has not reached the required level: The car radiator fan operates with electronic temperature control, and generally, the fan only starts rotating normally when the internal water temperature reaches the required level. If the temperature is too low, the radiator fan will not rotate. Long-term wear: Prolonged use of the fan can cause severe wear, as the motor may degrade. Once the motor's bushing wears out, it can easily burn out. Motor overheating: The fan assembly includes a motor, which has an overheating circuit breaker. If a short circuit occurs in the coil winding, it can cause a rapid increase in heat generation, leading to the motor not rotating.

What is the Mazda 6 coolant replacement tutorial?

Mazda 6 coolant replacement tutorial is: 1. Open the vehicle's engine hood and secure the support rod; 2. Locate the coolant reservoir in the engine compartment; 3. Find the coolant drain plug at the bottom of the vehicle's radiator, open the plug to drain the coolant; 4. After draining the coolant, tighten the cap; 5. Check to ensure the coolant is completely drained; 6. Pour new coolant up to the marked level. Functions of coolant: 1. Provides anti-corrosion protection for cooling system components; 2. Prevents scale formation, avoiding reduced radiator efficiency; 3. Ensures the engine operates within the normal temperature range.

What Causes the Buzzing Noise When Driving a Car?

Car driving with a buzzing noise is caused by: excessive carbon deposits in the engine, poor gasoline filtration, low-quality gasoline, aging spark plugs, engine malfunction, or cylinder failure. Solutions to the buzzing noise when driving a car include: 1. Replace the engine oil; 2. Clean carbon deposits from the engine; 3. Replace the spark plugs; 4. Conduct a comprehensive inspection and repair of the vehicle. The working principle of the engine: 1. Mix air and gasoline in a certain ratio to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to generate thermal energy; 3. The high-temperature and high-pressure gas acts on the top of the piston, driving the piston to perform reciprocating linear motion, and the mechanical energy is output through the connecting rod, crankshaft, and flywheel mechanism.

What procedures are required for vehicle transfer and file extraction?

There are many procedures required for vehicle transfer and file extraction. Documents: Vehicle license; Motor vehicle registration certificate; Motor vehicle registration supplementary form; ID card, driving license; Vehicle purchase tax certificate. Insurance: Compulsory traffic insurance policy for the current year; ID cards of both buyer and seller. For non-local residents, a temporary residence permit is required, and the buyer's temporary residence permit must be valid for at least one year. This requires careful attention. Materials needed for second-hand car transfer: Original and photocopy of the seller's ID card. Original and photocopy of the buyer's ID card. Original and photocopy of the motor vehicle registration certificate of the vehicle to be transferred. Original and photocopy of the vehicle license.

What are the effects of converting a car to natural gas?

Converting a car to natural gas can result in insufficient power, manifesting as sluggish acceleration and slow speed increase, which is particularly noticeable when using the air conditioning in summer. This is the most significant drawback. Below is an introduction to engine-related content: Energy conversion: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. Device: An engine can refer to both a power generation device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of an engine originates from English, with its original meaning referring to a "mechanical device that generates power."

Why does the engine shake and lose power after driving through water?

After a vehicle drives through water, engine shaking occurs because a small amount of water enters the high-voltage wires, and the engine air filter element gets soaked, leading to increased intake resistance and water entering the combustion chamber, resulting in poor ignition system performance.
