Why does the generator radiator overflow

The reason of radiator overflow in generator may be that the water jacket of the injector is not tightly sealed or cracked. There is a water barrier. The waterproof casing is connected to the waterway and sealed with a rubber sealing ring. After long-term operation, the connection between the cylinder head water jacket and the cylinder head will have small cracks due to aging, or the sealing will not be good due to the aging of the rubber. The burned mixture seeps into the water through tiny gaps, causing the water in the radiator to overflow.

The oil cooler may have 2 problems :

• The radiator core has cracks or blisters;

• The sealing rubber ring at the interface between the radiator core and the oil passage of the cylinder is not tight.

In this way, the oil will enter the water, and if too much oil enters the water, it will spill out of the radiator (this is easy to distinguish, because organic oil will spill out of the radiator with the water, and the oil can only become less and less. It will not change in quality). The sewer chamber of the radiator is connected by a plurality of pipes. If due to improper operation, the radiator is more fouled and the pipeline is easily blocked.When the engine runs at high speed, part of the water enters the small circulation through the water pump, and the other part enters the radiator water supply chamber. However, due to blockage of the distribution pipes, water overflowed from the water supply room. At this time, when you touch the top and bottom of the radiator,you will feel a significant temperature difference. When disassembling, just disassemble and assemble the radiator and unblock the pipes below; or add vinegar to the radiator, let the engine run for 5 minutes, and then change the water. After several cycles, the radiator can basically be cleaned.
