This ASHIKA thermostat, part code 38-07-702, is designed to regulate the engine's operating temperature. It plays a crucial role in the cooling system by controlling the flow of coolant. When the engine is cold, the thermostat remains closed, allowing the coolant to circulate within the engine block to reach its optimal operating temperature faster. Once the coolant reaches a specific temperature, the thermostat opens, allowing coolant to flow to the radiator for cooling. This process is essential for fuel efficiency, reduced emissions, and preventing engine overheating or damage. ASHIKA thermostats are manufactured to meet stringent quality standards for reliable performance.
