What Causes the BMW 5 Series Air Conditioning to Not Cool?

The main reasons why the BMW 5 Series air conditioning does not cool include: lack of refrigerant; damaged air conditioning flaps making it difficult to cool; excessively dirty condenser; damaged air conditioning compressor, throttle valve, or expansion valve; aging or loose belts, etc. Here are the details: 1. Solutions: Add refrigerant from the low-pressure side; release some refrigerant from the maintenance port on the low-pressure side of the air conditioning system; tighten the air conditioning compressor drive belt; replace qualified refrigerant and refrigeration oil; replace the compressor. Remove the installed GPS and test the air conditioning to see if it still does not cool. 2. Inspection: First, use a gauge to measure. The static pressure is about 5bar, which is normal. Use a computer diagnostic plan to check the power supply voltage of the electromagnetic clutch. The multimeter measurement result is 12V, which is normal. Then, measure the resistance of the compressor electromagnetic clutch. The result is infinite, while the normal resistance range for an electromagnetic clutch is 2.5-15 ohms. This exceeds the normal range, indicating that the compressor is damaged.

Can a motorcycle battery be charged directly on the vehicle?

Motorcycle batteries can be charged directly on the vehicle. Charging time: When using a charger for slow charging, it generally takes about 10 hours. Owners should not opt for fast charging due to impatience, as fast charging can damage the battery. Additionally, during charging, the voltage should not exceed 14.5 volts, and the current should not exceed one-tenth of the battery's capacity. Typically, the original battery of a motorcycle lasts 2-3 years, which is a normal consumption period. Motorcycle battery maintenance methods: Checking and replenishing the battery fluid level is essential. The fluid level in a motorcycle battery must be between the upper and lower limits and should never fall below the lower limit. If it does, it must be replenished promptly. When replenishing, do not add dilute sulfuric acid, as this can damage the battery due to excessively high electrolyte concentration. Also, avoid adding tap water or river water, as they contain calcium, magnesium ions, and other impurities. During charging, these substances can adhere to the electrode plates due to ionization and damage the battery. Therefore, only pure water, distilled water, or commercially available red battery replenishment fluid should be used. The fluid level in a motorcycle battery should be checked regularly, typically once a month. In summer, when temperatures are higher, it is recommended to check and replenish every two weeks. Note that sealed maintenance-free batteries do not require fluid level checks or replenishment, and their sealed covers should never be opened.

How thick is the sidewall of a 225 tire?

146.25 millimeters. The 225 represents the tire's section width of 225 millimeters, and the 65 represents the tire's aspect ratio, which is the percentage of the tire's section height divided by the tire's width. The tire's section height is the thickness of the tire's sidewall. For a 225/65 tire, the sidewall thickness is 225 × 65% = 146.25 millimeters. Below is a detailed introduction to Michelin's tire series: Pilot: A sports tire focused on high performance and handling, but with higher road noise, lower comfort, and a wear index around 300, making it less durable. It is mainly suited for high-performance sedans or sports cars. Primacy: Michelin's representative product for comfort and quietness, with models like Primacy-LC Bo Yue and Primacy-HP. The LC Bo Yue is positioned for quiet comfort and fuel efficiency, while the HP focuses on quiet comfort and handling. The latest 3ST model emphasizes safety, quietness, and comfort. Energy: Focused on economy and durability, this series offers excellent wear resistance, wet performance, and environmental performance, with models like XM1+, XM2, and MXV8. The XM1+ is positioned for economy and durability, the XM2 for durability and safety, and the MXV8 offers better comfort and handling. Latitude: Designed for SUVs, featuring excellent off-road performance, comfort, wear resistance, and durability, expanding Michelin's product coverage in the SUV tire market.

Why can't fuel be added to the fuel tank?

It may be due to hot weather causing increased internal pressure in the fuel tank, which leads to fuel splashing out during refueling, triggering the fuel pump nozzle to shut off. Alternatively, fast refueling speed can cause fuel splashing and nozzle shut-off, or the complex structural design of the fuel tank's piping system may result in fuel splashing and nozzle shut-off. There are three key points to note when installing a fuel tank: 1. Storage location: The fuel tank must be placed in a safe location to prevent fire hazards. The tank or fuel barrel should be stored separately in a visible area, at an appropriate distance from the diesel generator set, with a strict no-smoking policy enforced. 2. After placement: The highest fuel level must not exceed 2.5 meters above the base of the diesel generator set. If the fuel level in a large fuel depot exceeds 2.5 meters, a daily fuel tank should be installed between the depot and the generator set to ensure the direct fuel delivery pressure does not exceed 2.5 meters. Even when the diesel generator set is turned off, fuel must not be allowed to flow into the diesel engine by gravity through the fuel inlet or injection lines. 3. Resistance requirements: The resistance at the fuel port must not exceed the specified value for all diesel generators. This resistance value is based on the fuel tank being half full.

Will Exhaust Backfire Damage the Car?

Exhaust backfire will not damage the car. Here is a detailed explanation regarding the phenomenon of exhaust backfire: 1. Cause: When the engine is running at high RPM, some of the injected fuel does not completely burn. This unburned fuel then enters the hot exhaust pipe along with the exhaust gases and reignites. The gasoline explodes inside the relatively confined exhaust pipe, producing a crackling sound. 2. Additional Information: Not all cars can produce exhaust backfire sounds. Generally, special exhaust systems or high-displacement performance cars are required to generate backfire sounds. The main component affecting a car's exhaust note is the muffler in the mid and rear sections of the exhaust system.
