First need to address the reasonable control of a good cooling fan.The cooling fan of the original car to control the coolant temperature signal received by the engine control unit according to the cooling fan turned on and off,the engine control unit of local damage,the restoration of the related electronic components is extremely difficult.Therefore,the maintenance staff decided to switch to a new cooling fan control mechanism,carburetor type Xiali the cooling fan control mode applies here.

Remove the coolant temperature switch,a thread at the loading with the match three links,including the interface.Three links,the structure is a modified internal exchange tee yellow brass (brass in many hardware stores can be easily purchased,modified work please turner production) after a good amount of size.Another at both ends of the three-way interface,one end of the installation removed to the coolant temperature switch,and plug and; one end fitted with a carburetor Xiali coolant temperature switch.Next,cut off from the engine control unit leads to the cooling fan auto relay control line and the line of control is transferred to a plug on the carburetor coolant temperature switch.Conversion is completed the test,the cooling fan has completely returned to normal work.

Comments: In the engine control unit is difficult to repair,carburetor type the Xiali engine cooling fluid temperature switch to control the operation of the cooling fan to avoid the replacement of relatively expensive engine control unit.The conversion work in a more critical aspect is the production of the trigeminal interface.Turner hands must match with the engine block,internal thread,external thread size match with the old and new two temperature switches,accurate measurement,and to ensure the smooth flow of internal waterways.
