Refine S2 Universal Thermostat L52G-82-M100 (4A91/4A9T), Efficient Temperature Control

Weifan S2 uses four engines 4A91/4A9T/4A90/4A92; if engine warms slowly, coolant temperature gauge fluctuates, or climate heater is not hot, thermostat sticking is the likely cause. Replacement parts L52G-82, L52G-82-M100 and 32350 installed on the cooling system outlet to accurately control coolant circulation path and maintain optimal operating temperature, preventing overheating or overcooling. Installation medium; about 1 hour; after replacement, improves long-distance driving stability.
