FAW Besturn B30/X40 Senya R7 Thermostat 1306050-26L Cooling System Temperature Control Assembly Original Factory Quality

FAW Pentium B30, X40, and Senya R7 owners: original thermostat 1306050-26L is the key component controlling coolant circulation in the cooling system. It opens or closes the valve based on engine temperature to keep coolant within the optimal operating range. Use genuine-quality parts; ensure precise fit after installation. When thermostat ages or fails, typical symptoms include fluctuating water temperature gauge, slow warm-up, or prone to overheating; replacement restores normal engine operating temperature, stabilizing fuel economy and power output.
