Removal

   

• When working on high voltage system, the work should be performed by technicians who have completed the relevant training. It is because that lack of knowledge of the high voltage system can lead to serious accidents due to electric shock or electric leakage.

• When working a high voltage system, the technician must be recognized and observe "General Safety Information and Caution". If do not follow, serious accidents like electric shock and short circuit are caused.

• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.

   

• Use a fender cover to protect the painted surface.

• Be careful not to damage the connector when disconnecting.

• When disconnecting a quick connector, refer to the following according to the type of quick connector.[Type A]- Remove the while pressing the quick connector clamp (A) in the direction of the arrow.- Do not touch the rubber seal (B) inside the hose.

[Type B]- Pull the quick connector clamp (A) in the direction of the arrow to separate the clamp and remove the hose.- Do not touch the rubber seal (B) inside the hose.

1.Disconnect the battery negative ( - ) terminal and the service interlock connector.(Refer to Battery Control System - "Auxiliary 12 V Battery")

2.Remove the front under cover.(Refer to Motor and Reduction Gear System - "Front Under Cover")

3.Drain the battery system coolant.(Refer to Cooling System - "Battery Coolant")

4.Disconnect the Electric Water Pump (EWP) cooling hose (A).

5.Disconnect the distribution pipe cooling hose (A) after releasing the quick connector.

6.Disconnect the distribution pipe cooling hose (A) after releasing the quick connector.

7.Disconnect the coolant temperature sensor (A), and then disconnect the high-voltage battery cooling hose (B) by releasing the quick connector.

8.Disconnect the motor and reduction gear oil cooler hose (A) after releasing the quick connector.

9.Remove the coolant distribution pipe (A) after removing the bolts and nut.

Tightening torque :16.7 - 23.5 N·m (2.0 - 2.4 kgf·m, 14.5 - 17.3 lb·ft)

Installation

1.Install in the reverse order of removal.

   

Make sure the quick connector is installed securely after installing coolant hose.[Type A]- Make sure the quick connector (A) is installed securely.

[Type B]- Make sure the quick connector and quick connector clamp is installed securely.- Make sure that the quick connector protrusion (A) fits into the groove (B).

2.Fill the high voltage battery system coolant.(Refer to Cooling System - "Battery Coolant")

   

Using the KDS under actuation test, perform air bleeding actuation for Electric Water Pump (EWP).
