What are the effects of a faulty car thermostat?

[LaMadeline]

Damage caused by a faulty car thermostat: Increased engine wear and shortened engine lifespan. More information about the thermostat is as follows: 1. The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. 2. The thermostat must maintain good technical condition; otherwise, it will severely affect the normal operation of the engine. For example, if the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine warm-up time, resulting in the engine temperature being too low.
