Restore reliable cooling performance with the XYWZV Engine Coolant Thermostat, engineered to fit select Hyundai and Kia models and their 3.3L and 3.8L V6 engines. Designed as a direct OE replacement for the original parts 25500-3L300 and 255003L300, this component is built to help your engine reach and hold the optimal temperature with minimal effort.

Why it matters

While driving through hot days, cold starts, or spirited highway runs, a properly functioning thermostat can contribute to steadier thermal management and potentially more predictable engine response. It’s not a guarantee of improved mileage or power, but it’s a plausible step toward maintaining your vehicle’s cooling system health.
