Here are the specific reasons why the Haval H6 suddenly fails to start: 1. Carbon deposits in the engine causing ignition difficulties: Accompanied by slight shaking at idle, cleaning the throttle and fuel injectors can resolve the issue. 2. Weak ignition energy from the spark plugs: Failure to replace the spark plugs after the maintenance cycle leads to a significant drop in ignition energy, causing misfires in severe cases. 3. Insufficient fuel line low pressure: Low oil pressure in the low-pressure fuel line directly results in the engine requiring a second ignition. Specific checks can be performed on the fuel pressure regulator, fuel pump, fuel filter, and internal pipelines. 4. Battery depletion: Jump-starting the car using another vehicle or battery can solve the problem. 5. Incorrect engine timing: Mismatched engine timing can cause difficulties in starting. Certain models may experience timing belt misalignment when replacing the generator belt, leading to ignition problems.

Is It Necessary to Add Engine Anti-Wear Additives for a New Car?

It is not necessary to add engine anti-wear additives during the first maintenance of a new car. Because the first maintenance may occur just after or even before the break-in period, during which the new car is not suitable for using engine anti-wear additives. At this stage, the car requires the driver to operate it correctly for proper vehicle break-in, ensuring smoother performance in the future. Using anti-wear additives at this time is not only wasteful but may also create dependency for the vehicle. Below are some precautions for the first maintenance: 1. Generally, the first maintenance only requires an oil change and filter replacement. If the service suggests replacing other parts, the customer should be cautious to avoid being deceived. The first maintenance is for a new car, and if too many components are replaced or added, it raises questions about the car's quality. 2. During the first maintenance, ask the 4S shop technician to perform basic vehicle inspections, such as checking the car's coolant, fuel filter, air filter, power steering fluid, etc., to ensure they meet specifications. 3. Before the first maintenance, it’s best to review the vehicle maintenance manual and follow its instructions to avoid being misled by the 4S shop.

What Causes the Noise in the Power Steering Pump?

The noise in the power steering pump may be caused by the pressure relief valve operating, a clogged filter, a faulty power steering pump, or insufficient power steering fluid. Below are the specific details: Pressure Relief Valve Operating: The sound produced when the pressure relief valve is operating is normal; Clogged Filter: A clogged filter can cause the pump to make noise. Over time, the oil reservoir with a filter can become clogged with dust, debris, or oil sludge, requiring the filter to be cleaned; Faulty Power Steering Pump: Issues with the power steering pump, such as air intake, leaking high-pressure oil pipes, or problems with the oil reservoir, require repair at a 4S shop; Insufficient Power Steering Fluid: If there is insufficient power steering fluid, simply add more. When adding fluid, be careful not to mix different types of oil, as mixing power steering fluids can accelerate oil degradation, increase mechanical wear, and potentially lead to mechanical failures.
