Can the car be started after being submerged in water and the water recedes?

After a car has been submerged in water and the water recedes, it should not be started. Here are the specific details: 1. Reasons: If a car has been submerged in water, attempting to start it can cause significant damage. After submersion, water may have entered the engine and other components. Starting the engine in this condition can cause severe damage, potentially leading to complete engine failure. In such cases, it is necessary to call a tow truck to transport the vehicle to a repair shop for a thorough inspection of the damage. 2. Insurance Claims: If the vehicle is covered by flood insurance, the insurance company will provide compensation after the vehicle has been submerged. Without flood insurance, the owner must bear the repair costs themselves. Mandatory insurance and some commercial insurance policies do not cover any damages caused by water submersion.

How to Troubleshoot EECU Malfunctions?

EECU troubleshooting methods are as follows: 1. It may be an issue with the CAN bus, or the CAN bus connector may be loose or have poor contact. 2. Inspection revealed that the shutdown switch wiring harness connector (located near the front wheel) had water ingress, resulting in corroded pins. 3. After derusting and rust-proofing the pins, reconnecting them resolved the fault. When communication between the engine ECM and the instrument panel is interrupted, the instrument panel will report this fault. The ECU is a crucial computer in a car, responsible for regulating engine operation. The ECU relies on numerous sensors to collect information and then uses actuators to control engine operation. If the car is equipped with an automatic transmission, there may also be a TCU, which is specifically designed to regulate the transmission.

What is the typical mileage for a vehicle's break-in period?

Car break-in period refers to the initial driving phase of a new vehicle or after a major overhaul, typically ranging from 1,000 to 1,500 kilometers. This is the fundamental mileage required to ensure proper contact, friction, adaptation, and stabilization of mechanical components. Below is relevant information about the break-in period: 1. Concept: The break-in period generally refers to the process where mechanical parts make initial contact, experience friction, and gradually fit together during early operation. 2. Precautions: Avoid emergency braking whenever possible: Emergency braking not only shocks the braking system during break-in but also increases impact loads on the chassis and engine. It's best to avoid emergency braking within the first 300 kilometers of driving. Avoid overloading: Operating a new vehicle at full capacity during the break-in period may damage components. Therefore, during the first 1,000 kilometers, the load should generally not exceed 75%-80% of the rated capacity.

Why does the car air conditioner suddenly stop cooling?

The following are the reasons why the car air conditioner suddenly stops cooling: 1. Clogged air filter: No air or weak airflow from the air conditioner. It is necessary to check whether the air filter is dirty, whether the blower can operate normally, and whether the air conditioning flap motor can switch normally. 2. Lack of Freon: The air conditioning system is low on Freon. It is necessary to check whether the system is leaking. After confirming the repair, add Freon to the standard range. 3. Dirty radiator condenser: The engine cooling system is faulty, causing the water temperature to be too high, such as the cooling fan not working, resulting in poor heat dissipation of the radiator and condenser. 4. Damaged air conditioning sensor: Incorrect data from various sensors such as the air conditioning pressure sensor and evaporator box sensor, causing the air conditioning system to fail to adjust correctly during regulation.

What causes backfiring and poor acceleration when cold but normal operation when warm?

The reasons for backfiring and poor acceleration when cold but normal operation when warm are as follows: 1. Carbon deposits in the throttle body and combustion chamber. During cold starts, the fuel injection duration is extended. Due to carbon deposits, some gasoline is absorbed by the deposits, leading to temporary unstable ignition. Additionally, incomplete combustion causes flammable gas mixtures to ignite in the exhaust pipe, resulting in backfiring. 2. When the engine warms up, the gasoline absorbed by the carbon deposits evaporates, stabilizing the engine. This explains why such issues do not occur when the engine is warm. 3. Causes and prevention of carbon deposits: (1) Prolonged idling can easily lead to the formation of carbon deposits in the car. (2) Regularly performing necessary cleaning of the car's intake system is the most effective way to reduce carbon deposit formation. Therefore, owners can perform necessary cleaning of the car's intake system at around 30,000 kilometers.

How to Adjust a Shimano Derailleur?

Check if all cable housings are in the correct positions, properly seated in their respective frame brackets, and if the shift cable is correctly installed. Shift the lever to a middle gear, such as the 4th gear. Adjust the limit screws: The function of the limit screws is to prevent the chain from falling off the smallest cog or getting caught between the cassette and spokes.
