How to Prevent Transmission Failures in GAC Trumpchi GS4?

Methods to prevent transmission failures in GAC Trumpchi GS4 are as follows: 1. Master the transmission oil replacement cycle: The internal control mechanism of an automatic transmission is very precise with small matching gaps, so the oil replacement cycle for most automatic transmissions is generally two years or 40,000~60,000 kilometers. During normal use, the operating temperature of transmission oil is usually around 120 degrees Celsius, thus requiring high-quality oil that must be kept clean. Secondly, prolonged use of transmission oil can lead to sludge formation, which may increase wear on friction plates and components, and also affect system oil pressure, thereby impacting power transmission. Thirdly, sludge in dirty oil can hinder the movement of valves in the valve body, affecting oil pressure control and causing abnormal transmission operation. Regular inspections are necessary. 2. Correctly replace transmission oil: A better method is dynamic oil replacement, using specialized transmission cleaning equipment to fully circulate the old oil during transmission operation, draining it completely before adding new transmission oil, achieving a replacement rate of over 90% and ensuring effective oil change. 3. Check if the automatic transmission oil level is normal: The method for checking automatic transmission oil differs from engine oil. Engine oil is checked when the engine is cold, while transmission oil needs to be preheated to about 50°C, then the gear lever should be shifted through all gears for 2 seconds each before placing it in park. At this point, the oil level on the dipstick should be between the maximum and minimum marks. If it is insufficient, add oil of the same quality promptly.

Will Insurance Cover the Car if It's Flooded in Heavy Rain?

Whether insurance covers a car flooded in heavy rain depends on the following scenarios: Stalling and getting flooded during driving: If you have vehicle damage insurance, but the car stalls and gets flooded while driving through water, coverage depends on the extent of the vehicle damage. Parked state: If you have vehicle damage insurance and the car is flooded while parked (e.g., in a garage or parking lot), coverage depends on the degree of damage to the car. No water ingress insurance: If you have water ingress insurance, the insurance company will cover the damage. Without water ingress insurance, only parts other than the engine may be covered. Restarting after stalling: If the car stalls in water and is restarted, resulting in damage, the insurance company will not cover the loss due to the restart. After the car is flooded, you can file a claim through vehicle damage insurance. After the incident, the owner should not attempt to move or start the vehicle but should report the incident to the insurance company immediately.

What Causes Blue Smoke When Going Uphill but Not on Flat Roads?

The phenomenon of blue smoke appearing when going uphill but not on flat roads is generally caused by oil burning. The reasons for this phenomenon are as follows: Thinning of Piston Rings and Cylinder Walls: The most common cause is that, under normal engine operation, the piston rings and cylinder walls, which are in constant relative motion, gradually wear thin over time. This creates a certain gap between the two contact surfaces, allowing engine oil to seep up into the combustion chamber through this gap. Under high temperature and pressure, the oil burns, resulting in blue exhaust emissions. Additionally, the air-fuel mixture may also leak down through the gap between the piston rings and cylinder walls, entering the crankcase. This reduces the engine's compression ratio, leading to a loss of power in the vehicle. Hardening and Cracking of Valve Stem Seals: Another reason is the hardening and cracking of valve stem seals. Engine oil in the valve chamber can seep through these cracks and flow down along the worn valve stems into the combustion chamber, where it is burned off. This causes the vehicle to exhibit blue smoke due to oil consumption.

Where is the Maintenance Manual?

The maintenance manual is usually handed over to the car owner by the 4S store along with the user manual when picking up a new car. Introduction to the Car Maintenance Manual: The car maintenance manual is provided by the 4S store at the time of purchase, one for each person, used to record vehicle maintenance information. It also allows car owners to check related maintenance content and precautions. Vehicle information that owners want to know can also be found, such as maintenance mileage and specific items for each maintenance. Maintenance According to the Manual: It is recommended to follow the maintenance manual for operation and maintenance. Regularly perform maintenance for the car owner, such as changing the engine oil every 5,000 kilometers. Some vehicles may have reminders.

Is it mandatory to purchase insurance at a 4S store?

Insurance does not have to be purchased at a 4S store. A 4S store is merely a service provider and has no authority to force car owners to buy vehicle insurance. If coercion occurs, consumers can report it to the relevant authorities. Legal provisions: According to the "Automobile Sales Management Measures": Dealers must not restrict consumers to specific providers of auto parts, accessories, financial services, insurance, rescue services, or after-sales services; nor can they force consumers to purchase insurance or require them to use vehicle registration services. Multiple purchasing channels: Car insurance can be purchased through various channels, not just 4S stores. Consumers can buy car insurance through both online and offline channels, as long as the channels are legitimate and qualified.

What Causes the Wheels to Cross the Line During Parallel Parking?

Parallel parking with wheels crossing the line may be due to improper control of the 30-50 cm distance from the edge line, resulting in the wheels crossing the line when entering or exiting the parking space. Here are detailed explanations and solutions: 30-50 cm distance from the edge line: Before starting parallel parking, ensure the vehicle is properly positioned, maintaining a 30-50 cm distance between the right side of the car and the edge line. Otherwise, significant errors may occur. Wheels crossing the line when entering the parking space: Turning the steering wheel too early can cause insufficient space in front of the vehicle, leaving excessive space behind and increasing the risk of crossing the edge line. Therefore, the first reference point must be accurately observed. Wheels crossing the line when exiting the parking space: It’s essential to ensure the wheels do not cross the line both when entering and exiting the parking space. Turning the wheel too early or too late can affect whether the car crosses the line, so timing is crucial.
