How to Open the Hood of a Qashqai?

How often should spark plugs be replaced in a car?

Under normal maintenance conditions, car spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the user manual for specific guidelines. The following standards can be used as a reference for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage ignition wires according to the firing order and secure the cover plate.

What is the difference between V and H rated tires?

The difference between V and H rated tires mainly lies in their maximum speed under load conditions, with V rated tires having a higher speed capability than H rated tires. The differences between V and H rated tires are as follows: 1. Durability: When tires roll at high speeds, they generate heat due to compression and deformation. Therefore, the higher-grade V rated tires have superior durability. To achieve this, enhancements are made to the tire shoulders and tread patterns, reducing the likelihood of deformation and improving wet traction performance. 2. Speed: Under load conditions, the maximum speed for V rated tires is 240 km/h, while for H rated tires it is 210 km/h. 3. Considerations when replacing tires: Replacing original V rated tires with H rated tires has no impact, as V and H ratings represent the tire's speed category, meaning the driving speed should not exceed the maximum speed. However, it is important to note that when selecting replacement tires, they should be of the same specification, structure, manufacturer, and tread pattern as the original tires to ensure consistency.

What to Do If the Car Has No Tire Pressure Monitoring?

If the car is not equipped with tire pressure monitoring, it is necessary to add a tire pressure monitoring device to prevent driving with underinflated tires. The specific steps to add a tire pressure monitoring device are as follows: 1. Open the packaging and check if all accessories are complete. Remove the original valve stem and install the sensor. 2. Reinstall the tire and wheel, inflate it, and perform a dynamic balance test on the balancing machine. When the display is first inserted into the cigarette lighter socket, the warning light on the display will turn red for about 2 seconds before turning off. Then, the indicator lights for each tire will cycle through. When the indicator light stays on a specific wheel, it means the current reading displayed is the tire pressure value for that wheel. The continuous cycling display of each tire's pressure value allows for clear monitoring of each tire's pressure condition. If the tire pressure fluctuates significantly, falls below, or exceeds the set pressure value, the warning light will illuminate to alert the driver to check the tire pressure. This small display terminal can also effectively and promptly indicate if the tire temperature is too high or if the battery is low.

Do You Need to Keep Your Foot on the Accelerator While Driving?

Whether you need to press the accelerator while driving depends on the road conditions: 1. During driving, if there is no need to slow down or stop, your right foot should remain on the accelerator pedal (vehicles with cruise control do not require continuous pressing of the accelerator pedal once cruise control is activated). 2. During driving, if you need to slow down or stop, your right foot should be moved away from the accelerator pedal and, if necessary, press the brake pedal. If you are preparing to stop, your right foot should be moved away from the accelerator pedal and then press the brake pedal. After coming to a complete stop, if you do not intend to turn off the engine, there is no need to press the accelerator pedal, as the engine will automatically idle.

What kind of engine oil should be used for the Great Wall Fengjun 5 diesel version?

Great Wall Fengjun 5 diesel version can use C35W-30 engine oil. Here is some introduction about engine oil: 1. Engine oil: also known as engine lubricant, it can lubricate and reduce wear, assist in cooling, seal and prevent leakage, prevent rust and corrosion, and cushion shocks for the engine. 2. Composition of engine oil: the base oil of engine oil currently in use is composed of hydrocarbons, poly-alpha-olefins (PAO), and poly-internal-olefins (PIO), all of which are organic compounds made up of carbon and hydrogen. 3. Engine oil viscosity standard: SAE (Society of Automotive Engineers) viscosity classification is used to distinguish the different temperature ranges suitable for lubricating oils.

Does the Throttle Need Cleaning?

The throttle needs cleaning, and the cleaning cycle is approximately every 20,000 to 30,000 kilometers. Steps to clean the throttle: 1. Open the car's engine hood, locate the black air pipe connector where there is a metal component secured with a metal clamp—this is the throttle; 2. Use a screwdriver to loosen the metal clamp on the throttle. It doesn't need to be completely removed, just loosened sufficiently. Then, remove the plastic tube connected to the throttle; 3. After removing the throttle, the inside will be visible, covered in oil stains and carbon deposits. Take out the throttle cleaner, spray it inside the throttle a few times, and watch as the oil stains and carbon deposits dissolve; 4. Wipe it clean with a paper towel, then use your finger or another object to push open the movable baffle inside the throttle. Spray a few more times inside and wipe clean again with a paper towel; 5. Once cleaned, reassemble everything in reverse order. Start the car and let the engine run for a while to expel any remaining debris from the throttle.
