||
Overheating |
• Engine overheating • Temperature gauge rising to HI |
• Inspect GDS/KDS scanner. |
① Check DTC code. ② By using KDS/GDS, check for current flowing in wiring connecting to WTS. |
Additionally inspect wiring and connector. |
• Inspect coolant leakage. |
Inspect leakage from EHRS and coolant tube (including WTS assembly). (Visually
check for signs of efflorescence after evaporation of coolant.) |
For unit failure, replace EHRS and coolant tube. |
||
• Inspect operation of EHRS valve (vehicle inspection). |
Drive until the engine coolant is sufficiently warmed up, and then inspect operation of wax actuator.[Visually check the lifting amount of wax actuator: Over 8 mm (0.315 in.) at 80°C (176°F), or over 9 mm (0.354 in.) at 90°C. (194°F)] |
For unit failure, replace EHRS. |
||
• Inspect operation of EHRS valve (unit inspection). |
① Remove the wax actuator. ② Rotate the valve lever to check for smooth operation.
|
For unit failure, replace EHRS. |

Overheating |
• Engine overheating • Temperature gauge rising to HI |
• Inspect operation of wax actuator. |
① Remove the wax actuator. ② Immerse wax actuator in water and gradually heat the water. ③ Inspect the opening temperature and forward stroke of the valve. [Opening temperature: 71 ± 2°C (159.8 ± 35.6°F), Forward stroke : at 80°C (176°F) 8.85 ± 0.65 mm (0.348 ± 0.026 in.]
|
For unit failure, replace EHRS. |
• Inspect WTS. |
① Remove the WTS. [Disconnect connector (a). → Remove clip (b).] ② Immerse temperature detector of WTS in water and gradually heat the water. ③ Check the resistance according to temperature. [20°C (68°F) : 2.45 ± 0.14 kΩ, 110°C (230°F) : 0.1471 ± 0.002 kΩ]
|
For unit failure, replace WTS. |
