| Description |
| • |
Engine coolant is used for circulating heat in order to heat and cool the transmission oil. |
| • |
Rapidly elevates the transmission oil temperature during the initial cold start of the engine. |
| • |
Prevents over heating of the transmission oil while the vehicle is moving. |
| • |
Transmission oil warm-up and cooling can be done with a single system. |

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: Headlamp Leveling System
