Where to Add Transmission Oil for BAIC Senova?

The transmission oil filling port for BAIC Senova is located at the bottom of the transmission. There are two screw ports in this position - one is the drain plug screw and the other is the fill plug screw. After unscrewing the fill plug, you can add transmission oil. Here is additional information: 1. It should be noted that when replacing new transmission oil, the old transmission oil needs to be completely drained first. Loosen the screw to let the dirty oil flow out completely, wipe the drain port clean, tighten the screw back, and then you can add new transmission oil. 2. The replacement cycle for transmission oil is two years or 60,000 kilometers. The replacement cycle of transmission oil is calculated in the same way as the car maintenance cycle, mainly based on the vehicle's mileage and usage time, but it also needs to be determined according to the actual usage condition of the vehicle. Function of transmission oil: Transmission oil mainly serves to lubricate and clean. During operation, it can protect the transmission and extend its service life. The quality of transmission oil directly affects the working efficiency of the transmission. It also has certain antioxidant properties, which to some extent reduces component corrosion.

Why is there water leaking under the car?

Water dripping under the car is a normal phenomenon. Here are the specific reasons for water dripping under the car: 1. Air conditioning condensation: Dripping occurs after running the air conditioning for a while, which is normal. This happens because during air conditioning operation, moisture in the cabin condenses on the evaporator to form water droplets, which are then discharged outside the vehicle through the drain pan and drain pipe. 2. Exhaust emissions: When gasoline is injected into the cylinder and mixed with air, it fully combusts in the combustion chamber, primarily producing carbon dioxide and water. Some of this water is emitted into the atmosphere as gaseous water vapor at high temperatures, while some is discharged in liquid form.

What to Do After Paying Off a Car Loan?

After paying off the car loan, you should contact the lending bank within 10 working days after the final payment is made to obtain the loan clearance certificate and retrieve the mortgaged documents. Below are the required materials for handling the vehicle release procedure: 1. Vehicle-related documents: Original "Vehicle Registration Certificate" and "Motor Vehicle Mortgage Registration/Pledge Filing Application Form," stamped with the official seal of the mortgagee. 2. Borrower-related documents: Identity proofs and copies of both the vehicle owner and the mortgagee, along with a power of attorney from the mortgagee stamped with the official seal.

Should the Mustang use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the Mustang should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, the Mustang's fuel cap also indicates the recommended octane rating. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the required gasoline grade. High compression ratio engines can still be tuned to use lower octane gasoline because factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Mustang occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the current tank is used up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, manifesting as poorer performance in actual driving experience. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane number, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is generated during the upward stroke. This resistance makes the engine run very unstably. Mild knocking only increases noise without significant engine damage, but severe knocking indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What are the disadvantages of double-wishbone independent suspension?

The disadvantages of double-wishbone independent suspension are that it occupies a large space and has high costs. Below is relevant information about independent suspension: 1. Function of independent suspension: As a connecting force-transmitting component between the frame (or body) and the axle (or wheels), the independent suspension of a car is also an important part to ensure driving safety. 2. Classification of independent suspension: Independent suspension is divided into two main categories: single-wishbone independent suspension and double-wishbone independent suspension. 3. Advantages of independent suspension When the wheels on both sides of an independent suspension are impacted, they do not affect each other. Moreover, due to the lighter weight of this suspension and its strong buffering and shock absorption capabilities, the ride comfort is relatively good.

What is the Difference Between Minor and Major Car Maintenance?

Difference between minor and major car maintenance: Minor maintenance refers to routine service items performed at the manufacturer-specified time or mileage intervals to ensure vehicle performance after driving a certain distance, including oil and oil filter replacement. Major maintenance, based on minor maintenance, involves replacing the oil, oil filter, air filter, and fuel filter at the manufacturer-specified intervals. Minor maintenance includes: 1. Engine oil: Engine oil is the lubricant for engine operation. It lubricates, cleans, cools, seals, and reduces friction in the engine, significantly lowering wear on engine components and extending their lifespan. 2. Oil filter: A component that filters the engine oil. Engine oil contains certain amounts of gums, impurities, water, and additives. During engine operation, metal particles from friction, airborne impurities, and oil oxidation products are all filtered by the oil filter. If unfiltered oil enters the circulation system, it could adversely affect engine performance and longevity. Major maintenance includes: In addition to oil and oil filter replacement, major car maintenance also involves the following two items: 1. Air filter: The engine inhales large amounts of air during operation. Without filtration, dust in the air can accelerate wear on the piston group and cylinder. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring." The air filter's role is to remove dust and particles from the air, ensuring the cylinder receives sufficient, clean air. 2. Fuel filter: The fuel filter provides the engine with clean fuel by filtering out water and impurities from the gasoline, optimizing engine performance and offering the best protection.
