Exhaust method of Yang Guang 400 rowing boat after adding antifreeze

Automatically exhaust air to return pipe.

As long as the return pipe does not block the smooth flow of water, there is no need to manually exhaust; There are two water pipes on the kettle of this car, one is to feed the engine, and the other is to the return pipe at the water tank or cylinder head. It should be noted that after adding enough water, don't screw on the lid immediately, start the engine, and then screw it on after the running water in return pipe continues. If the lid is tightened in advance, the air in return pipe will not be discharged, and the water in the system will not circulate, which is prone to high temperature.

No water pipe: there is only one water pipe on the kettle, so the car must be vented manually, otherwise how much antifreeze can be transferred out; What I want to say here is that the exhaust position must be selected correctly, otherwise the air exhaust will not be complete.

note:

1. Exhaust must be carried out when the engine is cold.

2. It is forbidden to open the water tank cover or drain valve under the condition of high antifreeze temperature to avoid burns.
