What to Do If Changan's First Maintenance Exceeds Three Months?

What are the reasons for rapid consumption of car antifreeze?

The reasons for rapid consumption of car antifreeze are: 1. Radiator damage, poor sealing of upper and lower water chambers causing coolant leakage; 2. Overflow tank, water pump joint surface and loose connections in the cooling system pipelines leading to coolant leakage. Solutions for excessive antifreeze consumption: Regularly inspect all sealing points and connections, ensure proper tightening where needed, and never reuse leak-proof gaskets or tapes. The full name of antifreeze is antifreeze coolant, which prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head during cold winter parking.

What Causes Fluctuating Car Engine Temperature?

Fluctuating engine temperature in a vehicle is usually caused by wiring faults or sensor abnormalities. Related fault descriptions are as follows: Introduction to wiring issues: Primarily involves grounding problems. Poor grounding, insufficient grounding points, or accidental grounding of wires can all lead to unstable engine temperature. First, check the vehicle's grounding points for firmness and signs of rust. Then inspect the instrument cluster's grounding points for looseness or corrosion. Reasons for fluctuating engine temperature: Sudden temperature fluctuations while driving may be caused by system failures, specifically sensor abnormalities. Sensor issues typically stem from quality defects or temporary malfunctions. In such cases, performing a battery reset for initialization can help determine if the fault persists.

What is the reason for the sudden disappearance of the car dashboard speed display?

The reason is the damage to the vehicle speed sensor. Here are the relevant details: 1. Vehicle Speed Sensor: As the information source for the automotive electronic control system, it is a critical component of the system and one of the core research areas in automotive electronic technology. It detects the speed of electronically controlled vehicles, and the control computer uses this input signal to manage engine idle speed, torque converter lock-up in automatic transmissions, automatic transmission shifting, the opening and closing of the engine cooling fan, cruise control, and other functions. 2. Vehicle Speed: Vehicle speed refers to the distance a car travels per unit of time, commonly referred to as speed, with common units being kilometers per hour or meters per second.

How long does it take to get a new car license plate?

If you choose a custom license plate, it usually takes about 15 days to have it made. During the registration process, you will first be issued a temporary license plate and given a receipt for picking up the permanent plate. You can then take this receipt to the vehicle management office to collect your license plate when it's ready. Try to avoid the peak period for new car registrations if possible. The normal working hours of the vehicle management office are from Monday to Friday, 9:00 AM to 5:00 PM. The busiest day of the week is Monday, while Thursday and Friday tend to be the least crowded. You can plan your visit accordingly.

What is the function of automatic transmission fluid in cars?

Automatic transmission fluid in cars serves as a lubricant to maintain system cleanliness and prolong the lifespan of transmission components. It offers resistance to low temperatures and ensures effective lubrication even in cold conditions, reducing fluid loss under harsh operating conditions. Depending on the transmission structure, transmission fluids are categorized into automatic transmission fluid (ATF) and manual transmission fluid. Approximately 95% of automatic transmission fluids are red in color. Beyond lubricating and cooling the planetary gear set, their primary role is to transmit power. Under normal driving conditions, automatic transmission fluid should typically be replaced every 120,000 kilometers, while under severe driving conditions, replacement is recommended every 60,000 kilometers.

Is Waxing Necessary After Vehicle Crystal Coating?

After applying crystal coating to a vehicle, waxing is unnecessary. The circumstances requiring waxing and methods to determine coating failure are as follows: When Waxing Is Needed: If the crystal coating fails, it's advisable to wax the car. Minor scratches are inevitable during daily use, and without proper protection, prolonged exposure can easily lead to paint damage. How to Determine Coating Failure: Hydrophobic Test: If the coating is effective, water droplets will bead up like dewdrops on a lotus leaf when splashed on the paint. If it fails, water will spread and cling to the surface. Crystal coating enhances gloss; if the paint appears dull and the surface attracts dirt easily, the coating has likely failed.
