The Cummins diesel engine has a high temperature after replacing the radiator, and the downpipe is n

The Cummins B-series engine is the same as the domestic diesel engine. The principle is the same, that is, from the surface to the inside, from the outside to the inside, from the simple to the complex.

1. What we consider is whether the engine water tank is short of water (antifreeze), the water in the water tank (whether there is air in the antifreeze), and whether the water tank is blocked.

2. Check whether the water pump belt is slipping and whether the water pump impeller is damaged (the rapid heating up of the engine is likely to be these two reasons).

3. Check whether the thermostat is a fanka, but don't drop the thermostat again, because after the thermostat is dropped, the engine cooling system takes a small cycle, (the resistance of the small cycle is small).

4. Check whether the engine is overheating (you need to check the fuel system such as the amount of fuel injected).

There are several reasons for the large lower exhaust: the piston ring is worn too much, and the piston ring is blowing.

You can take a look at the respirator on the exhaust pipe, shaped like a bowl with a lid on it, remove it and wash the filter screen and then test it.

The water in the water tank is reduced very quickly, you check whether there is a problem with the oil, if the oil is black and does not turn gray and white, it is fine, if there is, then you can be sure that the cylinder liner has trachoma, which needs to be overhauled, by the way, change the ring and the cylinder liner piston, and the lower exhaust can also be solved.

In the future, we should pay attention to maintenance, and we should not leak the water filter, and if there is powder in the water filter, it can reduce rust and corrosion in the body.

Summary. Hello Cummins The main reason why the engine water pipe is not hot is that the upper water pipe of the engine is hot and the water pipe is not hot The reason why the water pipe is not hot is that the thermostat is damaged and cannot be opened or the cooling system has air resistance, and the coolant circulation is not smooth. Thermostat damage:

If you want to remove the thermostat, you should plug the small circulation at this time, so as to ensure that all the coolant is dissipated by the water tank. Automobile heat dissipation is a mixture of air cooling and water cooling, the heat dissipation of the engine is brought to the radiator through the coolant, and the natural wind and the wind of the fan then take the heat of the radiator away. The cooling system has air resistance

Poor sealing of the cooling system at the interface between the antifreeze tank and the water tank can lead to coolant leakage.

Hello dear, it is a pleasure to be able to serve you according to your description Cummins engine sewer pipe is not hot as follows.

Hello Cummins The main reason why the engine water pipe is not hot is that the upper water pipe of the engine is hot and the water pipe is not hot The reason why the water pipe is not hot is that the thermostat is damaged and cannot be opened or the cooling system has the first obstruction of gas mu, and the coolant circulation is not smooth. Damage to the thermostat: If you want to remove the thermostat, you should plug the small circulation at this time, so as to ensure that all the coolant is dissipated by the water tank.

The heat dissipation of the engine is to bring the heat of the engine to the radiator through the coolant, and the natural wind and the wind of the fan will take the heat of the radiator away. The cooling system has air resistance: the cooling system is not tightly sealed at the interface between the antifreeze tank and the water tank, which can lead to coolant leakage.

Hello, the engine is high temperature, but Zhongweiqin is the reason why the upper and lower water pipes are not hot, the thermostat is damaged and cannot be opened normally, resulting in the water in the heat dissipation tank and the water in the engine can not form a large circulation, resulting in high engine temperature. Introduction to thermostats: It is a valve that controls the flow path of coolant.

It is an automatic temperature control device, usually containing a temperature sensing component, which turns on and off the flow of air, gas, or liquid by means of thermal expansion or cold contraction. Introduction of cooling water pump: It is suitable for transporting clean water or liquids with physical and chemical properties in high-pressure operation systems, such as high-rise building water supply, boiler water supply, HVAC system and cold circulation, bathroom and other cold and warm water circulation pressurization and equipment matching, fire protection system and other transportation or pipeline pressurization.

Cemented carbide seals of different materials ensure that there is no leakage in the transportation of different media.

Engine overheating caused by insufficient cooling water. At this point, remember never to open the lid of the antifreeze jug immediately. Start by opening up your car to a ventilated, shady place.

Then open the hood and wait for the cooling water temperature to drop. If you have to open it immediately, you can use a large towel soaked in water and put it on the lid of the antifreeze kettle, and then try to open the lid slowly. When the steam comes out, the hand is quickly removed and when the steam is completely dissipated, finally the lid of the pot is opened and the cooling water is added.

Water leaks can also cause the engine to overheat. There are many small tubes installed on the antifreeze bottle, and it is possible that the hose is loose or damaged, causing water leakage. In case of emergency, you can wrap the damaged pipe with adhesive tape and make up the water before driving.

A faulty thermostat causes the engine to overheat. The thermostat is generally installed on the upper part of the engine. If the cooling water temperature does not reach a certain temperature, water cannot be sent to the tank.

Therefore, it may be due to the thermostat, so that the temperature reaches the base temperature and cannot send water to the tank, or the amount of water delivered is too small, causing the engine to overheat! Happy car.
