If the vehicle's water exposure is not severe, simply replacing the affected components may suffice; however, if the engine sustains serious damage requiring major overhaul, this will impact its service life. Main causes of engine stalling include: water entering the exhaust pipe; electrical system short circuits due to water intrusion; water penetrating engine intake mechanisms into cylinders. Additional details: Reasons for flooded car stalling: Moisture or water-induced short circuits in high-voltage distributor systems causing stalling, which prevents exhaust emission. Intake system water ingress (at air filter) leading to stalling. This scenario is relatively rare and typically occurs only under high water levels.

The impact of repairing a water-flooded car is indeed significant. With years of experience in automotive research, I've observed common issues such as water entering the engine and damage to the electrical system, as water can cause component rust and short circuits. Even after repairs, residual moisture may corrode circuits or affect sensors, leading to reduced power or dashboard warning lights. Over time, these problems become more apparent, such as shortened battery life or malfunctioning air conditioning. It's advisable to regularly inspect wiring and the chassis to prevent new issues after rain. If the flooding was deep, mechanical components like the transmission may also be affected, causing gear-shifting difficulties. In summary, thorough testing of all functions post-repair is essential to avoid subsequent troubles.

Where is the car's air conditioning located?

Car air conditioning is installed on the engine. The air intake for the air conditioning is located under the wipers at the rear of the engine compartment, while the air vents are positioned in the middle of the dashboard and near the windows on both sides. Here is some related information: 1. The working principle of car air conditioning is as follows: The high-temperature, high-pressure refrigerant from the compressor enters the condenser through a high-pressure hose. Because the outside temperature is lower than the refrigerant temperature entering the condenser, with the help of the condenser fan, a large amount of heat from the refrigerant in the condenser is carried away by the outside air, thus condensing the high-temperature, high-pressure gas into a high-temperature, high-pressure liquid. 2. When this high-temperature, high-pressure liquid flows through the throttle expansion valve, due to the throttling effect, its volume suddenly increases and the pressure drops, turning into a low-temperature, low-pressure mist that enters the evaporator, where it vaporizes at a constant pressure.

What are the steps for refrigerant charging?

Refrigerant charging steps are as follows: Connect the manifold gauge to the compressor and refrigerant tank. Purge air from the charging hoses. Bring the system pressure to 0.4MPa. Turn on the air conditioning, open the manual valve on the manifold gauge, and charge refrigerant to the specified value. Extension: Air conditioning refrigerant is essentially the working medium in the refrigeration cycle, utilizing phase changes of the refrigerant to transfer heat - absorbing heat when vaporizing in the evaporator and releasing heat when condensing in the condenser. Currently, there are over 80 substances that can be used as refrigerants, with the most common being ammonia, Freon compounds, water, and some hydrocarbons.

China VI Emission Standard Symbol Identification?

The China VI emission standard symbol is identified as VI. More information about China VI is as follows: 1. The emission limits for China VI standards are: China VI A: Carbon monoxide 700mg/km, Non-methane hydrocarbons 68mg/km, Nitrogen oxides 60mg/km, PM particulate matter 4.5mg/km, etc.; China VI B: Carbon monoxide 500mg/km, Non-methane hydrocarbons 35mg/km, Nitrogen oxides 35mg/km, PM particulate matter 3mg/km, etc. 2. After the implementation of the China VI standard, it will only affect the registration of new China V vehicles. Already registered and annually inspected China V vehicles will not be affected in normal use.

Is it better to use 92 or 95 octane gasoline for the CR-V?

For CR-V models equipped with naturally aspirated engines, 92 octane gasoline can be used; for models with turbocharged engines, it is recommended to use 95 octane gasoline. Below are specific details about refueling the car: 1. Although 95 octane gasoline has higher anti-knock properties and better performance, vehicles designed for lower octane should not blindly opt for higher octane gasoline. Higher octane numbers are more suitable for engines with larger compression ratios, while engines designed for 92 octane often have smaller compression ratios. Using 95 octane gasoline may increase engine knocking. 2. Different octane grades of gasoline should not be mixed. For example, mixing 92 and 95 octane gasoline, even if done occasionally, could potentially affect the engine over time, leading to issues such as carbon buildup in the engine and increased fuel consumption.

How to Drain Engine Oil?

There are two common methods to drain engine oil: one is by removing the drain plug to let the oil flow out, and the other is by using an oil pump. It can be difficult to control the amount of oil flowing out when removing the drain plug. Alternatively, you can purchase an 80 cm long transparent hose from a hardware store to siphon the oil out. Additional information: 1. If thick blue smoke comes out of the exhaust pipe when the car is running, it indicates oil burning. Oil burning refers to engine oil entering the combustion chamber and mixing with the fuel, which can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, higher fuel consumption, and in severe cases, irreversible engine damage. 2. Another way to detect oil burning is to fill the engine with oil, drive for 1000 kilometers, and then weigh the oil filter. Repeat this process several times. If the oil consumption exceeds 0.3 liters per 1000 kilometers, it indicates an oil burning issue.
