Introduction The diesel engine has just been serviced and the water temperature is normal, but why is the water tank leaking? This means there is pressure in the water tank. There are several possible reasons: 1. It is likely that the cylindrical mattress is installed

The diesel engine has just been serviced and the water temperature is normal, but why is the water t

This means that there is pressure in the tank.

There are several possible reasons:

1. It is likely that the cylindrical mattress is installed upside down.

2. The old cylindrical mattress was used (the new cylindrical mattress was not replaced).

3. Use a damaged cylindrical mattress.

4. The process of tightening the cylinder head bolts is incorrect, resulting in failure of the cylinder mattress seal.

Causes of water leaking from the engine water tank:

1. The injector water blocking sleeve is not closed properly or has cracks. There is a blockage between the injector and the injector. Cylinder head on this series of engines. The water jacket and the water blocking jacket are connected with the water channel and sealed with a rubber sealing ring. After long-term use, the cylinder head will produce tiny cracks at the water jacket seals. and the cylinder headdue to aging, or the seal will not be tight due to aging of the rubber.

Well, the burnt mixture will enter the waterway through this small crack, causing the water to overflow into the water tank. ;

2. The water tank is too dirty: The upper and lower water chambers of the water tank are connected by several water distribution pipes if it is used carelessly and more taxes accumulate in it. The water tank makes it easy to block the water distribution pipe. When the engine runs at high speed, part of the water flows through the water pump and enters the small circulation, and the other part enters the water tank. water chamber, but because the water distribution pipe is not smooth, the water overflows from the upper water chamber. At this time, when you touch the upper and lower parts of the water tank with your hands, you will find ano obvious temperature difference. When disposing, simply disassemble the water tank and clean the water distribution pipe; or add vinegar to the water tank and run the engine for 5 minutes before changing the water. After several cycles, the water tank can be cleaned. This method is practical. and profitable. Low;

3. Oil cooler problem: At the oil cooler, the oil pressure is higher than the water pressure. There may be two reasons for the failure of the oil cooler: one is that the radiator core has cracks or blisters; the other is that the rubber sealing ring at the interface between the radiator core and the cylinder oil passage is not tightly closed. As a result, engine oil enters the water. Once excess engine oil enters the water, it overflows from the water tank.
