If the engine malfunction indicator light comes on after a car has been through water, it indicates there is a problem with the engine. This is mostly caused by belt slippage due to water entering the engine. Simply drying the water from the engine belt can resolve the issue. The impact on the car varies depending on the extent of water exposure. Specific details are as follows: If the car can still be driven normally: If only the air filter has taken in some water, it may affect the normal operation of the car's air conditioning. If not cleaned promptly, it can also create a musty odor inside the car. Additionally, if the car is not cleaned immediately after water exposure, residual dirty water in the chassis can corrode body components, potentially damaging the chassis over time. If water enters the engine: It can degrade the quality of the engine oil, accelerating wear on engine components and causing noise or abnormal vibrations while driving. If the car stalls after water exposure: And cannot be restarted, it may lead to severe wear on the engine cylinders, bent valves, or connecting rods. In severe cases, it can even render the engine irreparable. If the car stalls after water exposure, do not attempt to restart it to avoid causing further damage. In such cases, call a tow truck to remove the flooded car and take it to the nearest repair shop for maintenance and repairs.

How to Operate a Car When Wading Through Water?

The operation method for a car wading through water is: 1. If the water condition is unclear, you must get out of the car to scout the path or observe the driving track of the car ahead; 2. Open the engine hood to check the height of the air filter intake from the ground, and estimate it in the water; 3. Before entering the water, park the car for a while to let the engine temperature cool down; 4. When the vehicle enters the water, turn off the air conditioning and use a lower gear; 5. Lightly press the brake while driving to let the water vapor in the brake system evaporate and restore braking performance. The effects after a car wades through water include: 1. The engine may produce insufficient power and experience shaking issues; 2. The high-voltage distribution system may become damp or short-circuited due to water ingress; 3. Water may enter the exhaust pipe; 4. Residual water can prevent the brake disc and brake pads from fully rubbing, causing the car to lose braking force; 5. Debris can easily adhere to the chassis gaps, causing the chassis to rust; 6. Water mist may form inside the headlights, affecting the light transmission effect; 7. The wiring harness and circuit interfaces in the engine compartment may get wet, leading to short circuits.

What is the composition of the engine piston connecting rod assembly?

The composition of the engine piston connecting rod assembly includes: piston, piston rings, piston pin, connecting rod, and connecting rod bearing shells. The working principle of the engine piston connecting rod assembly is: to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, while transforming the force acting on the piston into the torque output by the crankshaft to drive the rotation of the car wheels. Precautions for the installation of the engine piston connecting rod are: 1. Clean the parts before installation, check the fitting clearance, and conduct technical evaluation; 2. When replacing a new cylinder liner, it should be done before installing the water stop ring; 3. Be careful not to scratch the piston or break the piston rings; 4. The vortex chamber pit on the top of the piston and the lubrication oil hole at the small end of the connecting rod should be on the same side and must face upwards.

What are the components of a vehicle's running system?

The components of a vehicle's running system include: the axle, wheels, frame, and suspension. The axle, also known as the shaft, is connected to the frame via the suspension and has wheels mounted at both ends. Its function is to transmit forces in all directions between the frame and the wheels. The wheel is a rigid rim that fixes the inner edge of the tire, supports the tire, and together with the tire, bears the load. The frame is the base of the entire vehicle, connecting all related assemblies into a whole and serving as the assembly foundation of the vehicle. The frame's role is to support the total mass of the vehicle and convert the torque from the transmission system into the driving force for the vehicle's movement. The suspension refers to all the force-transmitting connection devices between the vehicle's frame and axle. Its function is to transmit forces and torques acting between the wheels and the frame, as well as to cushion the impact forces transmitted from uneven road surfaces to the frame or body, reducing the resulting vibrations to ensure smooth vehicle operation.

How to Refuel a Car and What Are the Precautions?

Car refueling steps are as follows: 1. Park the car next to the gas pump at the gas station, with the fuel tank filler facing the pump. The position of the fuel tank cap is indicated on the dashboard, and the arrow points to the location of the fuel tank cap. 2. Turn off the engine. 3. After paying, you can ask the attendant to help refuel or do it yourself. Remove the nozzle from the pump's holder, insert it into the car's fuel tank filler, select the desired gasoline grade (octane rating), and trigger the nozzle; or hold the nozzle while the fuel is flowing; or set the nozzle to flow automatically, which will shut off when the tank is full. 4. Check if the oil level is normal. 5. Tighten and close the fuel tank cap.
