What are the opening temperatures of the two thermostats in the Nissan 2.0?
1 Answers
Nissan 2.0's two thermostats typically open at around 85-90 degrees Celsius. A thermostat is a valve that controls the flow path of coolant. It is an automatic temperature-regulating device, usually containing a temperature-sensing component that opens or closes the flow of air, gas, or liquid through thermal expansion or contraction. Introduction to thermostats: They automatically adjust the amount of coolant entering the radiator based on the coolant temperature, altering the circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it can severely affect the engine's normal operation. For instance, if the thermostat's main valve opens too late, it can cause engine overheating; if it opens too early, it prolongs the engine warm-up time, resulting in the engine temperature being too low. Thermostat arrangement: In general water-cooled systems, the coolant flows from the engine block into the cylinder head. Most thermostats are arranged in the cylinder head outlet pipeline. The advantage of this arrangement is its simple structure, making it easy to remove air bubbles from the cooling system; the drawback is that oscillation phenomena may occur when the thermostat is operating.
