Inspection
Remedy
Visual inspection
Inspect for shortage of coolant in reservoir tank .
Reinspect after replenishing coolant.
Inspect for coolant pollution after removing radiator cap.
  

Be careful when removing radiator cap from overheated vehicle.

Reinspect after replacing coolant.
Inspect for leakage and loose coolant hoses (radiator hose, heater hose, oil cooler hose, etc.).
Reinspect for leakage after reinstalling hoses and clamps.
Inspect for leakage on water inlet fitting mounting part.
Reinspect for leakage after replacing O-ring.
Reinspect for leakage after tightening to the specified torque.
Inspect drive belt (for normal operation of water pump).
Adjust drive belt tension or replace.
Inspect for leakage on water pump gasket mounting part.
Reinspect for leakage after replacing gasket.
Reinspect for leakage after tightening to the specified torque.
Inspect for loose coolant temperature sensor, cooling fan connector and pin.
Reinstall loose connector.
Replace relevant part if connector pin is damaged.
Inspect operation status of cooling fan.
- Check operation status by switching ON/OFF the heater control A/C.
  

Will not operate in cold ambient temperature.

Check mounting status of ground cable.
Diagnostic device
Inspect self-diagnostic code using KDS/GDS.
Check coolant temperature sensor, wiring, connector, etc.
Unit inspection
Inspect water pump impeller.
Replace water pump.
Inspect for foreign materials and status of thermostat valve.
Inspect unit after removing foreign materials.
Inspect for stuck thermostat valve.
- Immerse thermostat in water heated to over 95°C (203°F), then heat for at least 3 minutes to check valve lift.
  
•

Do not use water below 95°C (203°F).

•

Do not directly heat unit as this will damage thermostat.

Check valve lift.
- Replace thermostat if valve lift is below specification or valve is stuck.

Kia Stinger (CK) 2018-2023 Service Manual: CVVT (Continuous Variable Valve Timing) System

Description and operation Description Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load. By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance through reduction of pumping loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work.

Kia Stinger (CK) 2018-2023 Service Manual: Photo Sensor

Description and operation Description The photo sensor is located at the center of the defrost nozzles. The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar radiation received by its light receiving portion, generates an electromotive force in proportion to the amount of radiation received which is then transferred to the automatic temperature control module so that the solar radiation compensation can be performed.
