What is the water leakage in the engine room of diesel engine?

You have to find out if there is water or oil nearby. Fill it with water and run for a period of time, such as three or four days, to see if there is any water loss. If the water tank drain pipe leaks, either the rubber ring of the water tank cover is aging or there is something wrong with the inside of your engine. Under normal circumstances, water will not be lost for no reason. Water shortage or water on the ground is caused by engine failure, and the cylinder gasket is slightly damaged, which can't be found unless it is a professional maintenance person. At first, it just leaked a little, but after a long time, it broke down and I couldn't go. 2. Or there is something wrong with your thermostat, which is not fully opened. The water temperature rises and the circulation is not good, which leads to the high temperature opening the water tank cover and flowing into the ground. 3. There is something wrong with the ignition timing, which is also hot. 4. The aging of the machine is also high temperature. These will cause high temperature, water shortage and water leakage.
