Picture of the location of the water blockage of the diesel engine, as well as the illustrated tutorial for the replacement and removal of the water blockage

Diesel engines are divided into two types of dry cylinder liners: if it is a dry cylinder liner, there is no water blockage; if it is a wet cylinder liner, the water blockage is generally at the front and rear ends or both sides of the body, near the lower part of the cylinder liner.

Before replacing the water block, you need to drain the water, then remove the air filter and intake pipe, then move the turbocharger and generator away, and remove the heating pipe to see the water block. The engine water plug is a replaceable round cup-shaped metal plug. When removing the water plug, knock down one side of the water plug, knock it to the other side and lift it up, then use pliers to clamp it out, but it is best to drill a hole and hook it out. , To avoid accidentally knocking in the old water plug. After removing the old water plug, install a new one.

If the engine water plug is exposed to high temperature liquid for a long time, rust may occur for a long time. If the engine water plug on the cylinder head is rusted through, the liquid in the water channel will leak out, mix with the oil, and the engine will not be cooled enough, and a high temperature alarm will be issued. , And it will cause the oil to lose lubricity and increase engine wear.
