No, it must be installed according to specifications, otherwise it will fall off and cause the engine to be scrapped.
There are oil passages and water passages inside the engine block. They cannot be formed into one piece during casting. Various oil and water passages must be dealt with later. there will be gaps of different sizes on the cylinder block. A hole will need to be plugged later, especially the waterway water seal. Due to long-term contact with antifreeze, the common ethylene glycol antifreeze on the market will form acidic substances. high temperatures. If the preservative content of the antifreeze is not sufficient. If it meets the standard, it will gradually fail over time and be unable to neutralize acidic substances, resulting in antifreeze corrosion and water blockage.
After removing the timing chain covern, there is a water cap on the engine block. This water cap has been corroded, but it is not completely rusted and the antifreeze has not leaked from the cylinder. The water cap on the cylinder head is completely rusted. Antifreeze in the cylinder head water channel has flowed out and mixed with the engine oil. The engine oil has completely lost its lubricating effect. photo below, above the timing gear. The engine oil has been emulsified.
The water cap had just become corroded and rusted, and antifreeze began to slowly seep into the engine oil. The car owner did not notice that the engine noise became louder when the engine oil began to lose. Its lubricating effect, the car owner replaced it. Engine oil and engine returned to normal. When the antifreeze leaked again, it ultimately caused a high temperature alarm.
Tips for replacing the boengine water cap:
1. Before replacing the engine water cap, you must drain the water, then remove the air filter and intake pipe, then remove the compressor. Walk away from the generator and remove the heater hose to see the water blockage.
2. The engine water cap is a replaceable round cup-shaped metal cap. When removing the water cap, pull down one side of the water cap until the other side tilts, then use pliers to remove it. . Then install the new water cap.
How to drain the water tank of the diesel generator. Generator manufacturers believe that because the external ambient temperature is too low, the cooling water should be discharged after 15 minutes of shutdown when the water temperature has dropped, not immediately, otherwise the temperature difference between the fuselage and the external environment will be too important. , causing a breakdown of the generatordiesel generator. Some parts of the unit are deformed, which in turn affects the performance of the diesel engine (such as cylinder head deformation, etc.). When the cooling water stops flowing, it is best to shake the diesel generator several times. At that time, the remaining cooling water that does not flow easily will flow out due to the vibration of the diesel engine. can prevent the water on the cylinder head from freezing. If it falls, cooling water will flow into the engine oil pan. The operator should also note that if the water drain switch is not removed, the water drain switch must be in the open state after water draining is completed to avoid the remaining cooling water cannot flow temporarily for various reasons and freezes. the corresponding parts of the diesel engine. Generator manufacturers remind users not to turn on the switchof water release and everything will be fine when draining the water. They also need to pay attention to the specific water flow conditions to see if the water flow is steady and whether it is getting smaller. or faster and slower. If these conditions occur, it means that the cooling water contains impurities that impede the circulation of the water. The water flows normally. At this time, it is best to remove the water drain switch and let the cooling water flow directly from the body. If the water flow is still not smooth, use hard, thin steel objects such as wire to dredge it until the water flow is smooth.
