Does Using the Car's Air Conditioner to Blow Hot Air Consume Fuel?

1 Answers

Using the car's air conditioner to blow hot air does not consume fuel. For the heating system, there is no situation where it increases fuel consumption because the engine generates a large amount of heat after starting, and the cooling system assists in dissipating this heat. Therefore, the water-based heating system does not add extra fuel consumption during heat exchange. Here are some precautions when using the heating system: 1. First, do not turn on the heater immediately after starting the car because the heater relies on the engine's coolant temperature. When the engine is just started, the coolant temperature is low. Turning on the heater at this time will not only blow cold air but also increase the engine load, affecting the rise in coolant temperature. 2. Secondly, many new drivers are confused about whether to turn on the AC switch when using the heater in winter. Here are the correct steps to turn on the heater: Do not turn on the AC switch, remember not to turn it on. As shown in the figure below, adjusting the air conditioner to the red zone will blow hot air. Turn on the left-side internal circulation to warm up the car faster. You can also switch to external circulation after the interior temperature has risen.

What to Do When There's Abnormal Noise Upon Releasing the Accelerator?

When abnormal noise occurs upon releasing the accelerator, you should first check whether it is due to a cold start, inappropriate engine oil, or a backfire fault in the engine. Here are the detailed explanations: 1. Abnormal noise during cold start: When starting a cold engine, the oil pump cannot immediately establish oil pressure, causing insufficient lubrication of the valves and resulting in abnormal noise. After the car has been parked for a long time, the engine oil flows back to the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure, especially in the upper part of the engine, leading to insufficient lubrication of the valves. The hydraulic lifters and mechanical rocker arms fail to operate properly, causing abnormal noise. Solution: Reduce the number of times the car is turned off. 2. Abnormal noise caused by inappropriate engine oil: If the engine oil viscosity is too high, it may not provide sufficient lubrication, leading to abnormal noise. Solution: Replace with the required gasoline.

How to Deal with Rust Spots on the Car Body?

The methods for dealing with rust spots on the car body are as follows: 1. Clay bar: You can use a clay bar to scrub the car body surface during washing. A clay bar is a paint-safe material that can remove stubborn stains from the car body surface. To remove rust spots on white car paint, you need to rub back and forth vigorously several times until clean. 2. Polishing: If the clay bar cannot remove rust spots on white car paint, you can use polishing to eliminate them. Polishing can also remove minor scratches on the car body. 3. Touch-up paint: When the above two methods fail to remove rust spots on white car paint, you can lightly sand the area and then use white touch-up paint to dab a small amount of paint. 4. Preventive measures for rust spots: Wash the car frequently, apply protective measures for the paint such as waxing, sealing, coating, or ceramic coating. Avoid parking under trees, as many trees secrete sap that is difficult to remove from the car. Also, wash the car immediately after rain, as 90% of rust spots on the car body are caused by acidic substances in rainwater.

Can a New Car with a Manufacturing Date Over 6 Months Be Accepted?

Vehicles with a production date exceeding 6 months are considered inventory cars. Due to prolonged storage, these inventory cars may experience issues such as degraded engine oil, battery depletion, premature paint deterioration, damp electronic components, and aging rubber parts. Continuing to drive such vehicles can significantly reduce their service life. Therefore, purchasing a brand-new car is more reliable. Below are methods to identify inventory cars: 1. Check the production date: Vehicles with a manufacturing date over half a year can be identified as inventory cars. 2. Inspect tire rubber for aging: Inventory cars stored outdoors are prone to rubber aging due to exposure to high temperatures, sun, and rain, as are other rubber components (wiper blades, sunroof seals, etc.). 3. Examine the chassis: Before purchasing, request the 4S store staff to lift the vehicle and check for shock absorber oil leaks and rust on the exhaust pipe and muffler.

Do tires need to be replaced at 60,000 kilometers?

60,000 kilometers is the time to replace tires. The typical service life of tires is 4 to 6 years or 60,000 to 100,000 kilometers. Tires with tread depth below 1.6mm should be replaced immediately. Continued use may lead to risks such as tire blowouts or reduced grip causing skidding. Precautions for tire usage: 1. Avoid curbs to prevent tire compression: Tires can endure significant pressure, which may lead to ruptures, especially in summer when tires are less stable and more prone to bursting; 2. Avoid prolonged exposure to sunlight: Most commonly used tires contain a high proportion of rubber, which can age and soften under high temperatures. In summer, avoid prolonged exposure to direct sunlight as it may also cause tires to expand and crack, reducing their lifespan; 3. Avoid turning the steering wheel while stationary: Doing so concentrates tire wear on the same contact patch, leading to localized severe wear and shortened service life.
