Common Conditions for Vehicles After Rain
Condition 1: Weak Engine Start on Rainy Days
The most critical thing in the rainy season is the maintenance of the car’s&ld; heart&# 39;&# 39;&# 39; engine. Car owners may encounter problems with the engine that are difficult to start on rainy days, and sometimes even if they reluctantly start, they may feel weak.
Solution: The biggest cause of this problem is the leakage of electricity from the ignition system due to moisture.
If it is found that the ignition system is damp and the ignition is poor or the engine performance decreases, you can temporarily use a dry tissue or cloth to wipe the inside and outside of the power distribution panel, as well as the wires. If it is due to aging and leakage, it is necessary to replace it in a timely manner
On rainy days, it is common to wade in water. After wading, the performance of the car may decrease due to multiple water ingress, which can seriously cause the car to not drive normally. Of course, this is also highly likely due to leakage caused by humidity in the ignition system. Because turbid rainwater is the best conductor, the circuit is likely to cause a short circuit when encountering water
If the engine suddenly stalls while driving, do not repeatedly ignite and start it multiple times. You should wait for a while or get off the car to check the circuit, otherwise it is very easy to cause the engine to be scrapped. After the car has successfully waded through the water, maintenance should be carried out on the circuit equipment in a timely manner. The circuit can be wiped dry one by one with a tissue or dry cloth before starting

Condition 2: Side slip during driving
On rainy days, road slip increases the likelihood of side slip during vehicle driving. In addition to good driving habits and skills, the good condition of the brakes and tires is also the key to safe driving. The majority of car brake systems are dual circuit vacuum assisted hydraulic brakes. The brake fluid that transmits braking power has extremely strong water absorption. If water enters the brake fluid, during the braking process, The high temperature of friction will generate water vapor. And gas has compressibility, which can cause brake failure or even failure when compressed in brake fluid
Solution: For some vehicles with severe brake fluid absorption, water droplets can be seen on the brake fluid cup cover. So it is necessary to check the brake fluid during maintenance to ensure the safety of the driver and passengers. Once it is found that the brake fluid in a car absorbs water seriously, it should be sent to a professional repair shop for water removal
In addition, if it is found that the vehicle’s tires are severely worn and the tread patterns disappear before the rainy season, it is necessary to replace them. Some people lower the tire pressure every rainy season, with the aim of increasing the friction area between the tire and the ground, thereby increasing adhesion. However, it is actually counterproductive, making it more likely to cause tire slippage. Maintaining normal tire pressure is crucial

Condition 3: Wiper failure
If you often drive in heavy rain, unclear vision is definitely the biggest hidden danger, and the importance of wipers becomes apparent. At this time, if the wipers are in a condition such as vibration and abnormal noise, you should be careful, as this is likely to be a warning to you.
Solution: The increase in rainy season rain will inevitably make the wipers take on more responsibility, and for the inspection and maintenance of wipers, it is necessary to More meticulous. Because the road surface and visibility on rainy days are not conducive to driving, if the wipers cannot effectively remove rainwater, it will pose a great danger to driving safety. At this time, the wipers play a very important role, so its inspection and maintenance should be more meticulous and in place
The car owner can set the wiper switch to various speed positions, pay attention to whether there is vibration and abnormal noise during the operation of the wiper, check whether the wiper maintains a certain speed at different speeds, observe the wiping status, and whether there is uneven oscillation or missing scraping of the wiper support rod. Either of these two faults indicates damage to the wiper blades. At this point, you can pull up the wiper and touch it with your fingers on the rubber wiper blade to check for damage and elasticity. If the blades age, harden or crack, they should be replaced in a timely manner. The task of replacing blades is not complicated and can be done by oneself. Remember to first figure out which specification of wiper blades this car uses

Vehicle Maintenance Manual After Rain
1. Dehumidification inside the car
Actually, dehumidification should be done during rainy days. When it rains, turn on the cold air, which not only removes fog, but also has dehumidification function. When the rain stops, it is even more important to pay attention to removing accumulated moisture as soon as possible, otherwise it is prone to mold and other conditions. In addition to the welding of the door and the welding parts of the car body, the hinges and locks inside the door are prone to rust and corrosion Iron parts, such as those covered by door trim panels, are also prone to moisture. Therefore, on sunny days, car owners can find a cool place to open all doors and trunk covers, allowing moisture to be discharged and ventilated inside the car. Then, remove the foot rest and seat cover inside the car, rinse and dry them
2. Check the sunroof
The sunroof is a weak link in a car, and cannot form a plane with the roof. Therefore, it is destined to become a location for storing rainwater and dirt.
. When maintaining after rain, the first step is to clean the sediment or leaves adhering to the sunroof sealing strip, check if the sealing strip is deformed or has gaps, to prevent excessive rainwater from seeping into the sunroof and causing water leakage inside the car. Secondly, lubricate the sunroof guide rails. If the sunroof is not closed in a timely manner or leaks during rainy days, allowing rainwater to flow into the guide rails, it will dilute the lubricating oil on the guide rails. If left unattended for a long time, it will lead to insufficient lubrication of the sunroof guide rails and affect the tightness of the sunroof closing. Therefore, during maintenance after rain, it is necessary to check the lubrication of the sunroof guide rails and add lubricant in a timely manner
3. Maintenance of the chassis
The chassis is the area closest to the ground and is particularly affected by road conditions. Generally, this area is most prone to rust and spots, and the wheel cavity may even become loose and perforated.
. Therefore, it is necessary to pay attention to the cleaning and rust prevention treatment of the car chassis. When encountering heavy rain weather, the car can be cleaned after driving home. Firstly, some acidic substances can be washed away. Secondly, after driving in the rain, there will be sludge residue on the inside of the tires and chassis, and moisture will hide inside, which can easily lead to rust in these areas
4. Maintenance of the brake system
Due to the easy fusion of brake oil and water, during the rainy season, a large amount of wet water vapor accumulates on the brake cylinder and easily enters the brake fluid. If there is water entering the brake fluid, the high temperature generated by friction during the braking process will cause the water to vaporize.
. And gas has compressibility, which can cause brake failure or even failure when compressed in brake fluid. Therefore, after rainy days, it is necessary to pay attention to the oil inspection of the brake system and the bleeding treatment of the brake system
5. Check the circuit
The ignition system of a car may experience electrical leakage due to humidity. Once electrical leakage occurs, it will make it difficult for the engine to start.
. Therefore, in order for your car to operate normally, it is necessary to check the circuit in a timely manner after rain, and the most crucial thing is to check the high-voltage line. If there is water involved, the circuit equipment should be promptly treated afterwards. Non fiber tissues and textiles can be used to dry the circuits one by one before starting. Additionally, checking the brake system is also important. Due to the strong adsorption capacity of the braking system, rainwater can easily enter the brake fluid, which can affect the braking effect and in severe cases, may cause braking failure
