| Removal |
| 1. | Loosen the drain plug, and drain the engine coolant. Remove the reservoir cap to help drain the coolant faster. (Refer to Cooling System - "Coolant") |
| 2. | Remove the drive belt. (Refer to Timing System - "Drive Belt") |
| 3. | Remove the water pump pulley (A).
|
| 4. | Remove the water pump (A).
|
| Inspection |
| 1. | Check each part for cracks, damage or wear, and replace the water pump assembly if necessary. |
| 2. | Check the bearing for damage, abnormal noise and sluggish rotation, and replace the water pump assembly if necessary. |
| 3. | Check for coolant leakage. If coolant leaks from hole, the seal is defective. Replace the water pump assembly.
|
| Installation |
| 1. | Install the water pump (A) with the new gasket.
|
| 2. | Install the water pump pulley (A).
|
| 3. | Install the drive belt. (Refer to Timing System - "Drive Belt") |
| 4. | Fill the radiator with coolant and check for leaks. (Refer to Cooling System - "Coolant") |
| 5. | Start engine and check for leaks. |
| 6. | Recheck the coolant level. |

Inspection1.Turn the ignition switch ON.2.Connect the GDS.3.Emit intensive light toward the photo sensor using a lamp, and check the output voltage change.4.The voltage will rise with higher intensive light and reduce with lower intensive light.1. Auto light signal2.
DescriptionThe mode control actuator is located at the heater unit.It adjusts the position of the mode door by operating the mode control actuator based on the signal of the A/C control unit. Pressing the mode select switch makes the mode control actuator shift in order of Vent → Bi-Level → Floor → Mix.
