Summer is coming and the rainy season is coming again. Cars are most vulnerable to moisture and short circuit in rainy days.
In order to prolong the service life of the car and ensure our driving safety, ten car maintenance strategies in rainy season are summarized for your reference. A windshield should be clean.
Because when it rains cats and dogs, no matter how the windshield wipers of the car are wiped, the sight will not be clear and the vision will become very small.
To cope with such a situation, you should clean the windshield in front of the car at ordinary times.
Also, if the road surface of the car is relatively wet, the splashed mud must be cleaned with cleaning liquid. Second, keep the rear window of the rearview mirror clean.
The rearview mirror and the rear window will be contaminated with water drops, which will make you feel slow about the distance, so the eyes are easy to feel tired, so before starting, please clean the rearview mirrors and rear windows on both sides. Three check the wiper system.
Scraping caused by poor sight is a common car insurance accident in rainy days. The windshield wiper is indispensable for keeping a good sight when driving in the rain.
When it rains heavily, what appears in front of the driver is a vast expanse of white. If the wiper's ability to sweep water is seriously reduced, it will directly affect driving safety.
Therefore, in rainy days, the wiper system should be specially checked to see if the rubber of the wiper blade is aging, whether the blade of the wiper blade is deformed, whether the glass cleaning solution is sufficient, and whether the spray nozzle is normal, also remember to remove the debris between the wipers. Fourth, the Skylight drain tank should be cleaned.
If it is not used for a long time or the air in the environment is dirty, a lot of dirt will accumulate inside the skylight. For example: dust, leaves, etc.
These sundries will be rushed into the skylight drain tank by rainwater to block the skylight drain pipe, and when the drain pipe is blocked, the accumulated water in the drain tank will enter the interior of the vehicle after exceeding the height of the drain tank, causing damage to the interior of the vehicle.
The skylight drain pipe is generally located at the four corners of the skylight, connecting the skylight drain tank and the drain hole near the door or the front and rear fender. Five check the tightness of the vehicle.
The problem that is easy to occur in rainy days is that the water in the car causes the short circuit of the line.
The vehicle has rubber sealing strips on the door frame. On the one hand, it ensures the sound insulation of the vehicle, and on the other hand, it ensures the sealing performance of the whole vehicle.
In terms of vehicle sealing, old vehicles need special attention. They need to check and clean the door, the bottom drain hole and the rubber sealing ring on the chassis. If the drain hole is blocked or the rubber sealing ring is not sealed well, when driving in rainy days or passing through waterlogged roads, it is easy to cause water inflow in the car, and if serious, it will cause short circuit of the car power line and damage to the vehicle controller. Six, check the tire pressure.
Driving in rainy days will put forward higher requirements for tires.
The depth of fetal lines in rainy season should not be less than 2 to 3mm, and it is best to ensure that it is above 4mm.
Because the tread depth is too low, it is easy to form a water film between the tread and the water surface, resulting in vehicle deviation, tail flick and lengthening of braking distance.
It is best to use a special measuring ruler to measure the depth of the tread. If not, it can be replaced by a coin or a small wooden stick.
In addition, too low tire pressure will also aggravate the degree of skid.
Although the tire pressure is too low, it increases the friction force between the tire and the ground, thus increasing the adhesion force, but compared with the pressure per unit area of the tire and the ground, this adhesion force is very limited.
When a car brake
s in the rain, the most important thing is to have enough pressure to discharge the rain between the tires and the road surface to stop the car, so it is safer to maintain a high tire pressure in rainy days. Seven check the vehicle lights.
Before driving in rainy days, check whether the vehicle lights are complete, especially the front and rear fog lamps, because the fog lamps provide good lighting for the front and rear of the vehicle in low visibility weather, it will be used very frequently in rainy days and will not cause any problems. Eight check the brakes.
The brake part should also be checked to see if there is any oil leakage, whether the brake is normal, and whether the wear degree of the brake disc and brake pad is within the safe range. Nine, maintain a safe driving distance.
Due to the blurred vision in rainy days, car owners should ensure a wider safe distance than usual during driving. When driving in rain, they should pay attention to the driving speed and direction of the front car at any time, never accelerate overtaking because of the slow speed of the front car.
On the expressway, due to the relatively high speed of each lane, the driver's angle of view becomes narrower, and the road surface is slippery. When overtaking forcibly, it is easy to cause the wheel to slip by slightly moving the direction, causing accidents such as vehicle rollover.
Ten, avoid the vehicle passing through the road with deep water.
When driving in rainy days, pay attention to avoid passing through places with deep accumulated water.
If you have to wade in the driving, you should set the gearbox at 1-2 Low speed pass in one breath (
Automatic models without manual mode can also be hung in L gear)
, Do not rush at high gear and low speed to make the vehicle pass slowly and smoothly, and avoid inhaling water into the air filter, causing the engine to enter the water and turn off.
