Seven Common Vehicle Faults in Hot Weather

Boiling is actually caused by high engine temperature. Generally, the cooling system of a car is all right, which will not happen under the normal use of the car. Too little cooling liquid and deterioration easily affect the cooling effect, and it is also easy to boil in traffic jams and long-term idle driving.

Prevent boiling:

Check antifreeze regularly, fill it if it is missing, and change it if it is broken!

If there is leakage, it should be repaired in time;

Ensure that the cooling fan can work normally;

Don't let the water tank get too much dust, which will affect the heat dissipation.

Don't use cars too much. Remember to rest when the water temperature is too high.

Summer disease 2: air conditioning odor

When the air conditioner is turned on, the smell of mildew or decay comes to my face, and in many cases, a lot of dust is brought out, which makes the driver and passengers in the car very uncomfortable.

Solve the odor:

If the air outside is terrible, temporarily turn on the internal circulation;

Pay attention to the cleanliness of the air-conditioning system. If the air-conditioning filter is too dirty to produce odor, or the air-conditioning pipe has not been cleaned for a long time, solve it according to the reasons;

The evaporation box smells, so you can ask a professional for help.

Summer disease 3: the air output of air conditioner is small.

Turn on the air conditioner and find that the air volume is very small and there is no feeling of wind.

Solution:

The air conditioning filter screen is dirty and blocked, which easily leads to low air volume and needs to be replaced;

The blower is broken and needs to be repaired or replaced.

Summer disease 4: the air conditioner does not cool.

I haven't turned on the cold air conditioner for half a year, so I want to use it at high temperature. I found that the refrigeration was not enough, and I was still driving in a sweat.

Possible problems:

For human reasons, the air outlet is not opened, or the external circulation is opened, so the cooling effect of window opening is not obvious;

The air conditioning filter screen is blocked, and cold air cannot enter;

Leakage may occur if the refrigerant pressure is too high or too low;

The heat dissipation of the condenser is abnormal and the fan does not turn;

The air conditioner compressor is damaged and needs maintenance.

Summer disease 5: flat tire

When the ground temperature is high, the tire will be challenged. If the tires driving at high speed are unhealthy, the probability of puncture will increase, which is particularly dangerous.

Tire before puncture:

1, check the condition of the tire before going out, such as the depth of the pattern and whether there are cracks.

2. Keep the tire pressure normal. Too high or too low tire pressure will make tires more prone to puncture;

3, don't drive for a long time, in high temperature, should shorten the interval between parking and rest.

Summer disease 6: gearbox temperature is too high

This fault is mainly aimed at some automatic gearboxes equipped with gearbox alarm, which is similar to high engine temperature. If the temperature is too high to continue to use the gearbox, the gearbox will be in a protective state, cutting off or weakening the power output. If this state is maintained for a long time, it will have a great impact on the gearbox.

Preventive suggestions:

Once you find an alarm, you should immediately pull over to dissipate heat;

If it happens frequently, consider checking whether the transmission oil is too dirty or checking the transmission cooling system.

Summer disease 7: skylight door leaks

It is rainy in summer. If the skylight door is neglected to clean the sink, the rubber strip will be deformed, which will easily cause the door to leak in heavy rain.

Preventive suggestions:

1. If there is already a severely deformed rubber strip, replace the sealing rubber strip;

2, skylight drainage groove should be cleaned in time, don't let foreign body damage for a long time.
