What Causes the Loud Roaring Noise Around 2000 RPM in the Engine?

The loud buzzing noise when the engine reaches around 2000 RPM is generally caused by the operation of the electric cooling fan for the radiator during idle, or excessive clearance between pistons and cylinder walls during low-speed or gear changes. Below are the relevant explanations: 1. External environmental factors: Affected by weather conditions, if the car is in winter when temperatures are generally lower and the cold engine maintains high-speed operation, the phenomenon of loud engine noise is normal. 2. Internal engine failure: The engine is composed of various components, and if any internal part malfunctions, it may prevent the engine from operating normally, leading to increased noise. For example, blocked valves inside the car engine can cause increased noise. 3. Engine oil issues: Engine oil serves multiple purposes such as lubrication and cleaning for internal engine components. Therefore, if the oil is insufficient or deteriorated, it cannot provide the necessary lubrication, leading to increased wear during engine operation and consequently louder noise.

Is 8 Fuel Consumption Considered High?

For different vehicle models, the specific situation varies. A fuel consumption of 8 indicates that the vehicle consumes 8 liters per 100 kilometers. For a 2.0-liter engine, this can be considered relatively low fuel consumption. However, for a 1.5-liter or 1.6-liter engine, it is just average and not considered high. Below are some factors that affect fuel consumption: 1. Road conditions: When selecting a route, try to choose one that is less congested and shorter in distance to save more fuel. 2. Tire pressure: Some car owners might think that in hot summer weather, tires expand due to heat and therefore slightly reduce tire pressure. In reality, maintaining proper tire pressure is crucial for both fuel efficiency and tire lifespan. If a tire is underinflated by 40Kpa, its lifespan could decrease by 10,000 kilometers, and fuel consumption could increase by 3%. If tire pressure drops by 30%, at a speed of 40km/h, fuel consumption might increase by 5%-10%.

How to Turn on the Rear Air Conditioning in Geely Boyue?

Adjust the air conditioning mode to the upper vent position, and cool air will flow to the rear. Related instructions are as follows: 1. Turn on the internal circulation: The heating switch for the Geely Boyue is located at the internal circulation knob on the air conditioning control panel. 2. Reduce fuel consumption: When the Boyue's engine is just started in winter, there is no warm air (as the radiator temperature is insufficient to heat the air for warm airflow). Turning on the heating at this time will cause the engine to accelerate warming up.

Is a car considered flood-damaged if the engine didn't take in water?

As long as the interior, seats, and other internal components of the car did not take in water, it is not considered a flood-damaged vehicle. Below is relevant information: 1. Hazards: Flood damage causes significant harm to vehicles, particularly to the internal electronic control systems. The mixed rainwater is highly corrosive, damaging electrical functions and especially affecting future usage. If a car has been submerged, never attempt to start or run the engine, as this can cause severe deformation of the engine connecting rod. If a car is waterlogged, it is very prone to rusting of body components, shortening its service life and reducing safety. 2. Methods to identify flood-damaged cars: (1) Open the engine compartment. If the car has been submerged in water, even after cleaning, some wiring harnesses in the engine compartment will still show signs of mud or water stains. (2) If the interior has taken in water, the car must have been dried out. Seats that have been soaked and then dried will more or less still show signs of water damage.

Is No Deductible Coverage Unavailable Without Purchasing Vehicle Damage Insurance?

If you do not purchase vehicle damage insurance but have third-party liability insurance, you can still buy no deductible coverage. No deductible coverage can only be purchased as an add-on to commercial insurance and cannot be sold separately. Below is relevant information about auto insurance: 1. No Deductible Coverage: No deductible coverage is an add-on that requires a 'primary insurance' as a prerequisite for purchase and cannot be bought independently. Its insurance liability typically refers to 'after a special agreement, in the event of an accident, the portion of the deductible amount calculated according to the deductible rate stipulated in the primary insurance policy, which should be borne by the insured, will be covered by the insurance company within the liability limit.' The process for no deductible coverage is the same as that for regular insurance claims. 2. Vehicle Damage Insurance: Vehicle damage insurance under auto insurance is a commercial insurance and is voluntary to purchase. Vehicle Damage Insurance: When the insured or an authorized driver causes an insurance accident while driving the insured vehicle, resulting in damage to the insured vehicle, the insurance company will compensate within a reasonable range. Common types of vehicle damage include collisions, overturning (rollover), and natural disasters (such as hailstorms, heavy rain, explosions, etc.).
