Where is the automotive thermostat typically installed?

[VanKimberly]

Engine thermostats are installed in the following specific locations: 1. The engine thermostat is installed at the upper coolant outlet of the engine. Traditionally, most engine thermostats were installed at the upper coolant outlet of the engine. This design facilitates maintenance and allows air to be easily expelled when replacing coolant, reducing the likelihood of cavitation in the water system. The advantage of this arrangement is its simple structure and ease of removing air bubbles from the cooling system; however, its drawback is that the thermostat may produce oscillations during operation. 2. Installed in the radiator's outlet pipe. This arrangement can mitigate or eliminate thermostat oscillations and allows for precise control of coolant temperature. However, it features a more complex structure and higher cost, making it more commonly used in high-performance vehicles or cars frequently driven at high speeds during winter.
