Disassembling the engine does not have a significant impact. Following the normal procedures for disassembly and installation will not harm the machine's performance. Generally, engine disassembly for repairs is only necessary in cases such as water entering the engine, mixing of engine oil and water, or damage to the engine casing leading to oil or water leaks. Inspection criteria for engine overhaul: When there is severe oil consumption and blue smoke emission: If there is oil leakage, it is likely caused by aging valve seals or aligned gaps in the piston rings. For these two scenarios, priority should be given to inspecting these two automotive component groups before deciding whether an engine overhaul is necessary. When the engine produces abnormal noises: If severe knocking sounds are detected, or if the engine's main and connecting rod bearings are severely worn and the crankshaft shows significant wear, an overhaul should be considered. When cylinder wear reaches overhaul standards: Regardless of other symptoms in the car, the ultimate criterion for deciding on an overhaul is the extent of cylinder wear. If the cylinder's out-of-roundness reaches 0.125mm per 100mm of bore diameter, or if the cylinder's taper wear reaches 0.4mm per 100mm of bore diameter, meeting either of these conditions warrants consideration for an overhaul.

Is It Normal to Have Moisture Inside the Headlights?

No, it is not normal. Here are the relevant explanations: 1. Large temperature differences in winter can cause condensation inside the headlights: In the structure of car headlights, there is a ventilation tube connected to the outside. Its purpose is to allow the expanded gas inside the headlights to escape when the headlights are turned on and the temperature rises. When the headlights are turned off, the temperature drops, creating a pressure difference inside, which draws in outside air through the ventilation tube. If the air is humid, it can cause condensation inside the headlights, forming moisture. 2. Moisture is likely to form after heavy rain or car washing: If care is not taken during car washing, such as directly spraying the engine compartment or headlights with a high-pressure water jet, water droplets can flow directly inside. When the vehicle wades through water, since the engine and exhaust system are significant heat sources, rainwater falling on them can generate a large amount of steam. Some of this steam may enter the headlights through the ventilation tube.

What is the Lifetime Warranty for the First Owner?

The first batch of owners who purchase designated vehicle models can enjoy a lifetime warranty. Here are the relevant details: 1. The conditions for these restrictions include: the first owner; the vehicle must be maintained at a 4S shop for its entire lifetime; only the three major components are covered, and already damaged parts are not covered; the lifetime warranty will be voided if major components are replaced. The lifetime warranty is not the same as the vehicle warranty. 2. Additional information: The lifetime warranty is the manufacturer's commitment to the quality of the vehicle at the time of production, and not all damaged parts are covered for free repair. If the vehicle incurs a series of maintenance and repair costs due to normal wear and tear or component deterioration during regular use, and not due to the product itself, these are not covered under the lifetime warranty. This includes but is not limited to oil changes, fluid top-ups, tire rotation, engine carbon cleaning, oil and fuel filter replacements, and engine belt replacements. In summary, the lifetime warranty covers the replacement of parts damaged under non-human circumstances, excluding already damaged components.

What does the FAW-Volkswagen Dual Protection 1699 Package include?

It refers to the additional protection cost beyond the free warranty, with a total payment covering a 6-year warranty. Typically, the warranty period for vehicles is 3 years, but with the Dual Protection, the warranty period extends to 6 years. Here are the relevant details: 1. Vehicle warranty period: During the warranty period, not all repair costs are waived; it depends on the free items specified by the manufacturer. Usually, the owner's manual and the after-sales departments of various car 4S stores have relevant written explanations. 2. Warranty service: Failure to follow the prescribed maintenance schedule. After purchasing a new car, if the owner does not take it to the designated 4S store or the manufacturer's authorized service station for regular maintenance as specified in the transaction price model details, any issues that arise, even within the warranty period, will require the owner to pay a certain repair cost. Unauthorized vehicle modifications. Not covering modified vehicles is almost a consensus among all manufacturers regarding warranty issues. Some brands even stipulate in their warranty terms that if the owner changes the vehicle's purpose without authorization, such as for rental, leasing, or competitive racing, it will be considered an automatic forfeiture of the warranty rights.

How to Solve the Problem of Car Compressor Starting and Stopping Intermittently?

Compressor starting and stopping intermittently is because the air conditioning compressor automatically starts or stops according to the set temperature, rather than running continuously. Below are the relevant explanations: 1. Compressor phenomenon: The intermittent operation of the compressor is a protective phenomenon, representing the recovery time of the compressor's thermal protector. Normally, it only takes a dozen to several dozen minutes, but after long-term use of the compressor, these values may change. 2. Reasons for protection: One reason could be a lack of refrigerant in the system, causing the compressor's exhaust temperature to trigger thermal protection. Even if there are white bubbles at the needle valve, it only indicates the presence of refrigerant in the system, but the amount and whether there is a deficiency cannot be determined. Another reason could be excessively high compressor exhaust pressure, leading to increased operating current and subsequent thermal protection due to current. There are many possible causes, such as poor ventilation of the external heat exchanger, clogged heat exchanger, poor external fan motor, etc. Another possibility is a faulty thermal protector in the compressor, which is quite troublesome and usually requires replacing the compressor.

Where to Check Vehicle Demerit Points?

Methods for checking vehicle demerit points are as follows: 1. Query methods: Visit the service halls of traffic police branches in various districts and counties to check through touch query terminals; Log in to the external service websites of the public security traffic management bureaus of municipal public security departments, locate the vehicle violation query section, enter the license plate number and vehicle engine number, then click to query; Call voice inquiry hotlines; Check violations by sending mobile text messages. 2.
