How to diagnose and eliminate abnormal coolant consumption of automobiles?

Hello according to your description, check the external water leak first, then the internal water leak (white water vapor is emitted from the exhaust pipe), and then check if the water tank is frozen (sometimes the water drain switch is frozen in the open position).

General inspection of the cooling system.

a) Inspection of radiators and water jackets:

Mainly check whether there is mud, oil, deformation of heat sinks, etc. on the outside;

The main internal inspection is scale, oil stain, etc.; Can be cleaned with chemical solvents.

The cause of limescale: hard water filling.

The cause of oil pollution: the waterway is connected to the oil channel.

b) Inspection of the amount of coolant:

Method: The coolant level of the expansion tank should be between "low" and "full".

The danger of too low liquid level: easy to boil.

Reason: There is a leak somewhere, and it should be repaired in time.

3) Check the tension of the fan belt:

Hazards: Too loose: slipping, reducing the speed of pumps and generators, affecting their work, and accelerating the wear of belts;

Too tight: Pump bearings, generator bearings, and fan belts wear out faster.

Adjust the inspection method:

The bracket of the mobile generator (or the movement of the idler) is realized, adjusting it to the appropriate place to press the belt with the thumb and its downward displacement is 6, 13 mm.

4) Inspection of silicone oil clutch:

Method: Insert the end of the bimetal temperature sensing spring with a screwdriver, and turn the spring counterclockwise until it feels crushed, then the distance between the outer end of the measurement and the fixing groove should be 13mm, and the valve shaft should be able to rotate with the rotation of the spring.

In the event of a malfunction, the locking block behind the fan can be used to drive it directly and repair it when it returns to the station.

5) Inspection of thermostats:

Method: Place the thermostat in hot water, then heat it, check the temperature of the open and fully opened valves, and the lift of the valve when fully opened.

In view of the importance of temperature saving (failure to carry out large cycles can cause the engine to overheat and pull the cylinder), it is necessary to check it regularly (usually 5000km) and replace it if necessary. Hope mine is helpful to you, hope, thank you!!

Common causes of high engine water temperature are:1. The antifreeze in the engine cooling system is missing, which may be the leakage point of the engine, such as water pump leakage, pipeline damage, water tank damage, etc.;

2. The thermostat in the engine cooling system is faulty, resulting in high water temperature;

3. The cooling fan in the engine cooling system is not working properly, resulting in poor heat dissipation of the coolant;

4. The water pump in the engine cooling system is faulty, and the water pump does not rotate smoothly, resulting in poor flow of coolant.

If the coolant temperature of the car is too high, the vehicle should be stopped immediately and the engine should be turned off under the premise of safety. Open the cover of the machine to dissipate heat, and contact the repair agency for treatment. Avoid damage to the internal parts of the engine due to the high water temperature of the engine.

It is recommended that you use a decoder to decode, find the fault, and then go to the repair shop to find a professional for you to detect and repair, I hope my help to you, hope.

Driving at too high a temperature will cause the engine to pull the cylinder, and there are many reasons for the temperature to be too high: thermostat failure, fan failure, etc.

Hello, there is a fault phenomenon.

First of all, the water temperature gauge indicates that the temperature is high, even until the red line or water temperature warning light is on.

Secondly, there was smoke from the engine compartment and there was a burning smell.

Then, the water level in the kettle rises or even flows backwards, and the engine cooling fan keeps working. Hope.

The causes of abnormal coolant consumption are: damage to the radiator cover and gasket; coolant leakage; Coolant leaks from the cooling system into the engine; excessive fouling or clogging of the cooling jacket or radiator; Poor water seal of the water pump or excessive wear and leakage of the impeller seal gasket. Under normal circumstances, coolant is basically not consumed, and it is normal for coolant to lose 10% to 25% per year.

When it is found that the coolant consumption is abnormal, when the engine is running, first check whether there is any water leakage outside the cooling system, which can be eliminated by fastening. Leaking water from a pump drain hole is often mistaken for a leaking radiator outlet pipe. Dry, clean strips of wood can be extended to the pump drain hole for inspection.

If there is water on the sticks, the pump is leaking. If there is no external water leakage, it should be considered an internal water leak in the cooling system. If a large amount of water vapor is vented from the exhaust pipe while the engine is running, or if the dipstick is pulled out and there is coolant in the oil, the water jacket can crack or the waterway hole of the cylinder gasket is damaged, causing coolant to leak into the crankcase, cylinder, or intake and exhaust channels.

If the coolant of the car is depleted too quickly, check the whole car for water leaks. If there is no water leakage, the cylinder bed is corroded and the compressed gas is flushed into the waterway. In other words, the punch press needs to remove the cylinder head and replace the cylinder head and cylinder gasket.

Check the dipstick for bubbles and milky substances. If there is, it means that the cylinder head gasket is snorting, which is a phenomenon of oil rushing into the waterway. If there is no gas in the waterway, check the seal of the tank cover.

It is recommended to replace the water tank cover with one factory. It is recommended to check the drain valve of the water tank for water seepage and see if there is water rushing into the engine oil in the cylinder bed. If it is not a maintenance person, it is recommended to go to the repair shop for inspection.

First of all, it is recommended that you check the engine and heater tank for water leaks. It can sometimes be mistaken for air-conditioning water.

Secondly, it is recommended that you check if the engine is boiling water. Generally, the cylinder gasket is damaged or the cylinder head and cylinder block are cracked. Check for symptoms of water ingress into the engine.

Most of the reasons for excessive coolant consumption in automobiles are leaks, and there are two main reasons:

1.The radiator was damaged, and the poor sealing of the upper and lower water chambers led to coolant leakage.

2.Coolant leaks are caused by poor sealing of the joint surfaces of the overflow box and the water pump and the pipe fittings of the various lines of the cooling system.

3.In addition to leakage, there is another reason, such as damage to the cylinder gasket, the flatness of the joint surface between the cylinder head and the cylinder block, and the warping and loosening of the fastening bolts of the cylinder head, which leads to the high temperature and high pressure gas in the cylinder entering the cooling system, resulting in excessive consumption of coolant.

Regularly inspect the seals and their connections, and the part that should be tightened must be tightened, but do not exceed the specified tightening torque to avoid bad tightening. There is a torque table in the instruction manual for reference. Leak-proof gaskets, tapes, etc.

Do not reuse. Maintenance workers often use the seals you removed and put them on as they are, so they have to be replaced. This not only avoids excessive coolant consumption, but also effectively prevents oil pipe leaks and transmission leaks.

Normally, the coolant is not consumed too quickly or excessively. If the coolant is used too quickly, there may be air in the cooling system. When the engine is running, the vehicle is automatically emptied.

When the air runs out, the coolant decreases. It is also possible that there is a vulnerability. In this case, the owner had better go to the 4S shop and check it carefully.

Normal engine antifreeze does not decrease. Basically, there will be a small compensation tank on the cooling system. When the tank is pressurized, it releases the pressure into the compensating tank.

When there is a lack of water, it will inhale itself to make up for the effect. If there is a shortage of water almost every day, check the engine for leaks, check that the water tank cover is intact, the leaking liquid will evaporate if exposed to direct exposure, or the engine cylinder gasket will be damaged, resulting in antifreeze loss. Reasons for the sudden and large consumption of antifreeze in vehicles:

1。Abnormal consumption of antifreeze: abnormal consumption of antifreeze, or before leaving the car in winter, although antifreeze is added, the way is significantly shortened; 2.

Causes: Leakage: radiator, inlet and outlet pipes, water pumps (water seals, impeller gaskets), cylinder gasket waterway holes, cylinder channeling grooves; After parking in winter, the drainage or the foundation freezes; 3.

Fault diagnosis and troubleshooting method: first check the external water leakage, then check the internal water leakage (white water vapor coming out of the exhaust pipe), and then check whether the water tank is frozen (sometimes the drain switch freezes in the open position).

1. The radiator is damaged, and the leakage of coolant is caused by poor sealing of the upper and lower water chambers.

2. The leakage of coolant is caused by loose fittings of the overflow tank, water pump joint surface and various pipelines of the cooling system, resulting in leakage of coolant.

In addition to the leakage, there is also a reason for the damage of the cylinder gasket, the flatness of the joint surface between the cylinder head and the cylinder block, the warping, and the loosening of the fastening bolts of the cylinder head, which leads to the high temperature and high pressure gas in the cylinder entering the cooling system, resulting in excessive coolant consumption.

Regularly inspect the seals and their connections, and the tightening places must be tightened, but must not exceed the specified tightening torque, so as not to be broken, and there is a torque table on the manual that can be consulted. Leak-proof gaskets, tapes, etc. must not be used for the second time, repairmen often use the sealing ring you removed, and install it intact, and they must replace it, so that not only can avoid the phenomenon of excessive coolant consumption, but also the leakage of oil pipelines and oil leakage of the gearbox can be very effective in preventing blindness.

1. The radiator is damaged, and the leakage of coolant is caused by poor sealing of the upper and lower water chambers. 2. Check the water pipeline to see if there is leakage, and check each nozzle to see if it is caused by water seepage in the nozzle. 3. Check whether the water tank cover is faulty, generally if the water tank cover is not good, it will also appear in the bush when the water temperature is high.

The refrigerant is consumed too much, and it must be leaking.

1.First of all, start with the pot filled with refrigerant liquid. See if the inlet and return pipes are rotten, and if the kettle is broken.

Check the joints and pipes along the water pipe.

2.Check the cooling water tank to see if there is any damage or leakage.

3.Check the engine water pump assembly for any leaks.

4.Check the exhaust pipe for a lot of white smoke. Determine whether the cylinder mattress is flushed. Liquid leaks into the cylinder. (In winter, white gas is normally emitted).

Step by step, you can find the leakage of the hole.

What are the reasons for the rapid consumption of automobile coolant spring and old? How do you remove coolant from a car? In the absence of exposure, the consumption is too fast, it may be that the engine temperature is too high or the refrigeration liquid enters the oil.

Most of the reasons for the rapid consumption of automobile coolant are leakage, and there are two main reasons for Qixian: 1. The rental radiator is damaged, and the leakage of coolant is caused by poor sealing of the upper and lower water chambers.

What are the causes of car coolant depletion too fast? How to rule it out? I think that in this case, if you are fast, a noisy code is that you have frequent maintenance of the engine without lead, and it is too little to replace the oil of the engine.

What is the cause of the rapid consumption of automobile coolant? How does the radical exclusion tell you? Generally, when the coolant is consumed too fast, the temperature of the machine is too high, and the engine is first checked for fault.

If it is the reason why the car's coolant is consumed too quickly, the most important thing is a change in the consumption degree of her car's coolant.

What are the causes of car coolant depletion too fast? How to get rid of the branches that it consumes too quickly, and the reason is the performance problem? If you eliminate the disadvantages, you can install it directly.

Most of the reasons for the rapid consumption of cooling and slippery travel fluid are leakage, mainly due to the following two reasons: 1. The radiator is damaged, and the leakage of coolant is caused by the poor sealing of the upper and lower water chambers. 2. The joint surface of the overflow tank, the water pump and the pipe joints of each pipeline of the cooling system are loose, and the seal is poor, resulting in the phenomenon of coolant leakage.

What are the causes of car engine coolant depletion too fast? Today, I will analyze it for you. 1. The design of the cooling system is unreasonable (generally there are no immature cars, especially the Xinchang Hanche without this fault in the bridge, and most cars do not need to be considered); 2. Coolant leakage.
