BAIC Weiwang M20 high speed fan relay is always light burning

Hello, if it is burned out at high speed, it is still a short circuit problem of the fan itself, and it is not ruled out that the line is caused by a short circuit and heating.

Hello, this situation is generally caused by line failure or fan contactor, go to the repair shop to repair the line to replace the contactor.

The most direct reason for this situation is that the switches, circuits, plugs or relay contacts of the headlights need to be overhauled, and the short circuit problem is not easy to find, and it needs to be operated by a professional automotive electrician.

This is usually caused by a problem with the fan relay or line contact. It is recommended to go to the repair shop for a detailed inspection.

This situation is generally caused by line failure or fan contactor, and the contactor is replaced by overhauling the line.

Hello, check if there is a problem with the electronic dispersion, or if there is a problem with the quality of the relay.

In this case, you mainly check whether the resistance of the fan is normal, which may be caused by damage to the fan motor.

In this case, there may be a short circuit in the line or electronic equipment, and you need to go to the maintenance station for further investigation!

In this case, check the wiring and resistance of the lower fan. Most of them are short circuits caused by this situation, and you can check them.

This situation is obvious, check the relevant connection line must be caused by a short circuit problem, you can go to the repair station to further investigate.

Hello, check the wiring between the relay and the electronic fan, if there is no problem, it is the problem of the electronic fan.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

BAIC Weiwang Aimer 21 taxi radiator began to ring What's going on, this is because this radiator will produce a certain amount of harm, no way, really a few uses, so I think this should be the need to buy this radiator to use the balance, otherwise these radiators will always think, so this should be necessary to make some conditions for the temperature to be suitable, so I think this should still need to be paid attention to.

1. The cooling water in the engine water tank reaches the boiling point, and produces a large amount of water vapor, which will produce a large number of bubbles, and a part of the cooling system is occupied by bubbles, which will make the cylinder wall around the serious water deficit, so that the engine lacks cooling, and will reduce the strength of the piston, piston ring, connecting rod and other components, and even deform, and can not bear the normal load, and at the same time, it will also destroy the normal gap between the parts, so that the normal oil film can not be maintained between the parts, and the engine will pull the cylinder and pull the swag. In other cases, the entire engine can be damaged or even scrapped.

2. Selection of antifreeze: the freezing point of antifreeze is 10 lower than the minimum temperature in winter in the place of residence. The mainstream brand products of antifreeze are basically 40-60 yuan a barrel, with a capacity of 4 liters (the volume of the general car water tank is almost 4L).

The ** of the original concentrated antifreeze may be slightly more expensive, generally about 80 yuan a bottle, and the capacity is about that. When replacing the antifreeze, it is necessary to add it in proportion, and in general, the ratio of antifreeze to water is 1:1 or 1:

A ratio of 2 is sufficient.

3. The replacement cycle and replacement method of antifreeze.

The recommended replacement cycle of the original antifreeze will vary from manufacturer to manufacturer, but the vast majority of them recommend that car owners replace the vehicle antifreeze every 2 years, and some manufacturers show that their original antifreeze replacement cycle is 4 or 5 years. But no matter what, in short, it has to be replaced, which is nothing more than the length of the replacement cycle.

4. When replacing the antifreeze, the first and most important thing is to wait for the vehicle to cool down, and do not replace the antifreeze when the engine is at a high temperature. First, there will be a risk of burns, and secondly, the release of antifreeze during the "hot car" will also affect the cooling of the vehicle.

5. When filling with new antifreeze, you can directly pour about about (depending on the model) of antifreeze into the storage tank, and stop filling after the liquid level height reaches the upper limit max position. At this time, unscrew the drain screw next to the "water pipe", and continue to start filling the antifreeze, see the antifreeze gushing out of the drain screw continuously and without bubbles, and then tighten the drain screw, so far the first time to fill the antifreeze and release the air The work is basically completed.

After starting the vehicle, idle for 3-5 minutes to let the vehicle enter the normal working temperature, and make the new antifreeze can be fully circulated in the waterway in the car, and then turn off the engine, open the reservoir will find that the liquid level height has decreased, then only need to add an appropriate amount of antifreeze to keep the liquid level between max and min.
