DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a method for exchanging coolant for a vehicle engine, a method for cleaning the same, and a device according to the present invention will be described below with reference to the drawings. 1 is a radiator connected to an engine 3 by a lower hose 2. A radiator cap opening 1a of the radiator 1 is provided with an adapter 10 shown in FIG. The adapter 10 includes a coupler plug 10a, a lid 10b, and a joint 10c. The coupler plug 10a is connected to the new liquid tank 9 via the first connection pipe 21, and the lid 10b is similar to a conventional radiator cap. The joining portion 10c has a tapered shape formed of rubber or the like, and the joining portion 10c is prepared in various sizes depending on the size and depth of the radiator cap opening 1a of the radiator 1.

A heater 11 is provided in the new liquid tank 9 and a water level gauge 9a is provided. The heater 11 heats the new liquid, and the level of the new liquid is measured by the water level meter 9a. The new liquid tank 9 is connected to the replenishing tank 14 via the second connection pipe 22. When the new liquid in the new liquid tank 9 decreases to a predetermined water level, a new liquid is discharged from the replenishing tank 14 by a pump (not shown). It is automatically supplied into the tank 9.

Further, the waste liquid tank 13 is provided with a third connection pipe 23.
And connected to the upper hose 4 of the engine 3 to collect cooling waste liquid and accumulated matter (scale, sand, oxides, etc.) from the water jacket (not shown) of the engine 3 into the waste liquid tank 13. It is configured to be able to.

Next, the operation will be described. First, the car engine is turned on, and the engine is warmed by warm-up operation. Next, in the connection state of FIG. 1, the new liquid is supplied to the new liquid tank 9 to a predetermined water level, and the new liquid is 40-8
Warm to 0 ° C. When the power is turned on, a new liquid is sent into the radiator 1 by a pump (not shown). In this case, since the temperature of the new liquid is maintained at 40 to 80 ° C., the new liquid can pass through a heat-sensitive valve (not shown) in the radiator 1. When the new liquid is being supplied to the radiator 1, the engine is in operation. Therefore, the new liquid is automatically circulated by the circulation pump (not shown) of the engine 3, and the old cooling waste liquid is supplied to the third hose from the upper hose 4.
It is automatically sent out into the waste liquid tank 13 through the connection pipe 23 and collected. It should be noted that when the fresh liquid in the fresh liquid tank 9 decreases to the predetermined water level, the new liquid is replenished from the replenishing tank 14, and when the fresh liquid is less than the predetermined water level, the heater 11
Are controlled so as not to operate, and empty cooking of the new liquid tank 9 is prevented.

When water is put in the new liquid tank 9 instead of the new liquid, the water is supplied to the radiator 1 and the engine 3.
By supplying the waste water to the water jacket and collecting the waste in the waste liquid tank 13, it is possible to collect and wash the stagnant substances such as scale, sand, oxides, and the like that have accumulated in the radiator 1 and the engine.

[0019]

As described above, the method and apparatus for exchanging coolant for a vehicle engine according to the present invention have the following advantages. That is, the new liquid tank and the waste liquid tank are connected to the radiator and the engine, and the filling of the new liquid and the collection of the waste liquid can be performed automatically, thereby preventing pollution and improving the processing speed.
