What Causes Severe Vibration When the Car Air Conditioner is On?

How to Detect a Car Radiator Leak?

Check the car radiator for leaks by following these steps: 1. Check if the radiator cap is tightly secured. Frequent bumps during driving may loosen the radiator cap. If it's loose, tighten it. 2. Inspect the engine oil for signs of emulsification. Remove the engine oil filler cap to check for emulsification. If present, disassemble the engine and replace the cylinder head gasket. 3. Identify the leak location in the radiator. Try pressurizing the radiator with air to see where water seeps out under pressure, then decide on a repair plan based on the leak location. 4. Examine the radiator rubber hoses for leaks. If the hose connection is leaking, tighten the hose clamp with a screwdriver. If the hose is cracked, replace it with a new one at a repair shop. 5. Assess the radiator's quality. If the radiator has quality issues, replace it with a high-quality one at a repair shop.

Should a car use 92 or 95 octane gasoline?

Generally, naturally aspirated engine cars require 92 octane gasoline, while turbocharged engine cars usually need 95 octane gasoline. Some supercars equipped with large-displacement naturally aspirated multi-cylinder engines typically require 98 octane gasoline. Different octane ratings indicate varying levels of octane content - the higher the rating, the greater the octane content and the better the gasoline's anti-knock performance. When refueling, it's best to use the specified octane rating. Here's how to check your car's required fuel grade: 1. Consult the vehicle owner's manual. 2. Check the fuel grade marked on the fuel tank cap.

Is the Auto Start-Stop Function Useful?

Auto start-stop function is useful. It can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. Here are some precautions when using the engine auto start-stop: 1. Turn off start-stop in traffic jams: Repeated start-stop not only increases fuel consumption but also adds burden to the engine. 2. Turn off start-stop on slopes: Although the auto start-stop time is very brief, the engine start-stop on slopes may cause insufficient brake assistance. 3. Turn off start-stop when using air conditioning: Because the air conditioning requires relatively high power consumption, and when the engine is stopped, the vehicle's power may not be enough to drive the air conditioning, making passengers feel uncomfortable. 4. Turn off start-stop when wading: When the vehicle is wading, the speed is relatively low. At this time, once the brake is stepped on, the auto start-stop will intervene, and the engine will stop working, then the exhaust pipe will have negative atmospheric pressure, which will cause water to flow into the exhaust pipe. If the engine is started again, it will seriously damage the engine.
