What Causes the Squeaking Noise When Opening the Car Door?

The reasons for the squeaking noise when opening the car door are: 1. Rusty door hinges; 2. Friction from the door glass sealing strip; 3. Internal wiring harness hitting the door panel; 4. Dust accumulation on the windshield or aging door sealing strips; 5. Door deformation or improper installation. The design requirements for car doors include: 1. Ensuring passenger accessibility with a maximum opening angle of approximately 65 to 70 degrees; 2. Avoiding positional interference with other parts during opening; 3. Reliable locking when closed to prevent accidental opening while driving; 4. Excellent sealing performance; 5. Sufficient transparent area to meet lateral visibility requirements; 6. Adequate strength and rigidity to ensure reliable operation, reduce door vibration, enhance side collision safety, and prevent door sagging.

What does 'Please check the fuel filler cap' mean?

Please check if the fuel filler cap issue is caused by a faulty fuel cap sensor or a broken pull cord. Symptoms of a damaged fuel cap sensor: The car's fuel gauge fluctuates irregularly; the fuel gauge suddenly drops to zero; the fuel gauge reading rises unexpectedly. The fuel level sensor detects the position (height) of fuel in the container by measuring the change in capacitance between the sensor housing and the sensing electrode caused by the fuel, converting this change into a current variation. Broken fuel cap pull cord: When the fuel cap pull cord breaks, it prevents the fuel cap from opening normally. The method to open the fuel tank is as follows: use a small flat-head screwdriver, insert it into the middle rear side of the fuel cap, then slowly turn the screwdriver to the right. This will bend the metal latch inside the fuel cap, allowing it to open. Remember to visit a proper repair shop to replace the pull cord after opening.

Can You Drive with Low Coolant Level?

It is not recommended to drive with low coolant level recently, and it should be replenished promptly. The primary function of engine coolant is to maintain the operating engine within a normal temperature range. It helps cool down the engine when it overheats and also provides anti-freeze, anti-corrosion, and anti-scaling effects. If the engine coolant level is below the minimum mark but there is still some remaining in the reservoir, you can still drive. Although the coolant level is low, there is enough coolant circulating in the cooling system, which won't significantly affect the engine's heat dissipation. However, if the coolant level is so low that it's nearly empty, you should not drive. Continuing to drive will cause the engine temperature to rise increasingly without proper cooling from the coolant, leading to engine damage. Regularly check the car's cooling system and the remaining engine coolant level. If you find the engine coolant is insufficient, replenish it promptly.

Why Do 4S Stores Strongly Recommend Purchasing Extended Warranty?

4S stores strongly recommend purchasing extended warranty to ensure vehicle protection. Extended warranty is a product service that prolongs the vehicle's warranty period. Typically, cars come with a 3-year or 60,000-kilometer warranty. If certain components are damaged due to non-human causes during the warranty period, the 4S store will provide free repairs and replacements. Purchasing an extended warranty can extend the coverage from 3 years or 60,000 kilometers to 5 years or 80,000 kilometers, or even longer. New cars do not require immediate purchase of an extended warranty; it is advisable to assess the vehicle's condition after some use before deciding. If the vehicle's warranty is about to expire and the car is in good condition with no major issues in components, purchasing an extended warranty is not recommended. However, if the vehicle's condition is poor and certain components frequently require repairs, it is advisable to purchase an extended warranty.
