1. The general causes of engine overheating are: starting The machine is mainly overheated.It is caused by insufficient cooling water, poor radiator cover and thermosulator, loose or broken fan belt, blocked cooling water and insufficient oil in the lubricating oil system. The temperature control switch is out of control or failed, the relay and circuit are in poor contact, the fuse is broken, and the ignition time is too late.
2. The first fan problem. The fan motor does not move or the fan clutch fails, and the temperature cannot be cooled down normally. The exhaust problem is that the ternary catalyst is blocked or the tube breaks, causing the exhaust to be blocked and the engine to overheat.
3. Hello, the main reasons for the overheating of the car engine are probably as follows. First, the excessive water temperature of the engine caused by the loss of vehicle engine coolant. In this case, it is necessary to check whether the relevant water pipes have coolant leakage in time? If there is, it needs to be dealt with or replaced in time.
4. In order to give full play to the power and economy of the engine and extend its service life, it is necessary to ensure that the engine works at room temperature (80-90℃). However, after long-term operation after leaving the factory, the engine overheats due to wear, improper use, adjustment parameter changes and other factors, resulting in engine damage.
1. Replace the engine water temperature meter: Damage to the engine water temperature meter may lead to excessive temperature, and the water temperature meter should be replaced. Replace or repair defective parts: If all the above methods cannot solve the problem, check the engine at a professional vehicle repair shop. It may be necessary to replace or repair the engine cooling system, fan, water pump and other defective parts.
2. The treatment method of engine overheating is as follows: if the engine overheats, stop driving, and then open the engine hood to emit the heat of the engine. Most cars use water-cooled engines and rely on coolant circulation to take away heat.
3. Thermoster failure The function of the thermoster is to automatically adjust the amount of water entering the radiator according to the temperature of the cooling water, change the circulation range of the water, so as to adjust the heat dissipation ability of the cooling system and ensure that the engine works within the appropriate temperature range. If the thermostor fails, the car cooling system may not be able to perform a large cycle, resulting in an increase in the water temperature.
4. After finding that the engine is overheating in the process of driving the vehicle, you must slow down and find a safe place to park. Don't turn off the car after parking, let itIt has been idling, because after the car is turned off, the circulation fan will stop, and the antifreeze will also stop circulating, so that the heat of the engine cannot be brought out.
5. If the pump and fan belt are too loose or broken, the engine temperature is too high, and you need to go to the repair shop to replace the relevant parts; the radiator cover net or radiator core ventilation duct is blocked by debris, resulting in poor heat dissipation, resulting in excessive engine temperature.
1. When the engine overheats, the water temperature alarm light on the dashboard of the car will light up, and sometimes the engine compartment will be accompanied by "opening the pot". If the owner finds this situation, he should not continue to drive. Because if you continue to drive without knowing the specific cause of the failure, it may cause irreversible wear and tear to the engine.
2. After finding that the engine is overheating in the process of driving the vehicle, be sure to slow down and find a safe place to park. Don't turn off the car after parking, let it idle all the time, because after the car turns off, the circulating fan will stop, and the antifreeze will also stop circulating, so that the heat of the engine cannot be brought out.
3. Engine overheating treatment method: stop driving, and then open the engine cover to exhaust heat for the engine; if the engine water temperature shows that the engine is overheated during driving, you need to turn off the air conditioner; drive the car to a safe place and let the engine idle for a few minutes until the water temperature meter pointer returns to " The position between H" and "C".
4. If you want to add antifreeze at this time, you must wait until the temperature of the cooling water drops before adding antifreeze.Overhaul the electronic fan. After the water temperature is too high to the red line, the fan does not rotate, indicating that the fan temperature control switch has been burned out. At this time, the hood should be opened and the engine should be left for half an hour to wait for the temperature to drop for overhaul.
5. Insufficient coolant. Coolant leakage or lack of coolant will cause the engine water temperature to rise. At this time, we should check the coolant situation. If it is insufficient, first add it to the appropriate position, and then check whether the liquid level has dropped seriously in a few days. If so, we need to find the leakage location.
1. The first fan problem. The fan motor does not move or the fan clutch fails, and the temperature cannot be cooled down normally. The exhaust problem is that the ternary catalyst is blocked or the tube breaks, causing the exhaust to be blocked and the engine to overheat.
2. The cause and treatment method of excessive engine temperature are: lack or leakage of coolant. The treatment method is to replenish the coolant, and the cause of the leakage needs to be identified; the outer surface or inside of the water tank is blocked by dirt, which affects the heat dissipation or coolant circulation of the water tank. The treatment method is to clean the water tank or replace the new water tank.
3. Insufficient coolant. Coolant leakage or lack of coolant will cause the engine water temperature to rise. At this time, we should check the coolant situation. If it is insufficient, first add it to the appropriate position, and then check whether the liquid level has dropped seriously in a few days. If so, we need to find the leakage location.
4. Fan failure. The failure of the fan affects the normal operation of the fan. The specific reason is that the control switch process of the fan electromagnetic clutch or the fan motor is too late and too early to close;The fan never turns; the fan silicone oil high joint fails. 2 Insufficient coolant. The coolant is insufficient, and the internal consumption star is too large.
5. When the temperature and pressure of the upper and lower water pipes of the radiator will be different when the thermostor cannot be turned on. At working temperature, the opening of the main valve of the thermostulator is insufficient or fails to open, so that the water of the cooling system cannot enter the radiator (for large circulation).
1. The first fan problem. The fan motor does not move or the fan clutch fails, and the temperature cannot be cooled down normally. The exhaust problem is that the ternary catalyst is blocked or the tube breaks, causing the exhaust to be blocked and the engine to overheat.
2. For example, the reason for the high temperature is that the iron between the engine and the car frame is not good, resulting in the inaccurate feedback value of the water temperature sensor, resulting in the water temperature meter. The solution is to find a professional electrician to check or do it yourself. When you do it yourself, you only need to lead two from the negative pole of the battery to the engine and the car frame respectively. It can be solved by making the wire and iron.
3. CoolantInadequate Coolant leakage or lack of coolant will cause the engine water temperature to rise. At this time, we should check the coolant. If it is insufficient, first add it to the appropriate position, and then check whether the liquid level drops seriously in a few days. If so, we need to find the leakage location.
Solution for excessive water tank temperature: insufficient cooling water, resulting in engine overheating. At this time, you can't add cold water immediately, otherwise it is easy to cause deformation and cracking. You should first drive the vehicle to a ventilated and shady place, open the hood, and add water after the cooling water temperature drops.
The emergency response method when the water temperature of the vehicle is too high is as follows: the first step is to find a safe place to park and let the vehicle idle. Please do not turn off the engine.Because the cooling fan and coolant stop circulating after the engine is turned off, the engine becomes hotter.
If the temperature of the garage is too high, the following solutions should be taken: after parking on the side, the car should be turned off first to avoid engine damage. It should be noted that there are many reasons for excessive water temperature, and there is probably only one for each fault. Turn off all other functions in order to keep the waterproof temperature too high, resulting in engine damage.
Dealing with high water temperature of the car: When we encounter an alarm that the water temperature is too high, we should first slow down, and then drive the car to the side of the road. Don't rush to turn off the engine, because if the water temperature is too high, it will cause the piston, steel wall, cylinder, crankshaft, etc. to be too high, the oil to become thinner and lose the lubrication effect.
