1. The main reasons why the engine cannot start are: Check the distributor, spark plugs, high voltage lines, etc. have become damp due to the car being exposed to rain or washing. Check whether the battery voltage is sufficient;
Treatment method: turn off the vehicle first, dry the wet parts before starting the vehicle; use the connector cable to connect to other batteries (turtles) in the vehicle for temporary power supply; , so that Start the vehicle.
2. The vehicle stalls when changing gear. The main reasons are: the engine idle speed is too low; the idle speed shut-off valve is not tightened and the plug is falling out.
Treatment method: Adjust the gear to the correct idle ratio according to vehicle conditions; if the idle stop valve or part capIf the connector falls out, simply reinsert it.
3. The steering wheel shakes when the vehicle is moving. The main reasons are: if there are mud, stones and other debris stuck on the vehicle tires, the tires are deformed by the impact or the wheel weights; to fall ; all-wheel drive is not carried out after replacing the tire position.
Treatment method: Remove stones from the gaps between tires and debris stuck to the wheels. To avoid potential safety hazards, deformed tires should be replaced in time and find a nearby auto repair shop to install a balance weight. You should quickly find a professional auto repair shop for four-wheel alignment to avoid potential safety hazards.
Detailed information:
In addition, the system refrigerationair conditioners The principle is that the refrigerant evaporates quickly and absorbs heat, causing the temperature of the air passing through it to drop quickly. Since the evaporator temperature is low and the air temperature is high, the particles of water molecules in the air will condense into water droplets on the evaporator;
And dust in the air or small lint on clothes, seats, etc. The substances tend to stick to the surface of the condenser, causing mold and bacteria to multiply in large numbers. Therefore, the air conditioning filter element of the air conditioning system should be replaced regularly to clean the air passages and ensure the health of car drivers and passengers.
After wading through water on a rainy day, the generator belt continued to squeal, both at idle and while driving. In slow motion, I poured waterur the belt and it stopped squealing afterwards. for a moment he squeaked again. What will happen if it continues to squeak and you ignore it? After wading through water on a rainy day, the generator belt continues to squeal at idle and while driving. and it stops squeaking. After a while, it squeaks again. If it continues to squeak, what will happen if you ignore it? The power supply to the car's alternator is too low. Especially if the car is cold or the headlights are on and the windows are raised and lowered, you will feel that the power supply is insufficient. The correct solution in 2015 I appeared In this case, the 4S generator solution was broken. was to replace the generator assembly. Finally, I spent 50 yuan at a friend's house to replace the bearing, and the problem was solved. In this case, it is likely that there is a problem with the generator bearings. ImageNote that when the rotation of the generator is blocked, the rotation of the belt will also increase the friction, so abnormal friction and noise will also occur. If the belt is not loose, the bearing is probably the cause. It is easy to check the tightness of the belt. Press the belt between the two wheels to see if the belt is tight. If it's just a belt, because it's loose, it's very easy to tighten the belt. If you ignore this noise, the belt will soon be scrapped. In this case, you can go to the store to check. In this case, there may be sand or other foreign objects on the belt. It can be removed and cleaned or replaced. @2019
