Car Thermostat Teardown — What's Inside and How It

Video Description
Car Thermostat Teardown — clear, concise, and hands‑on. In this short video I disassemble a car thermostat, show the internal wax element, valve, and spring, and perform a controlled heat test to demonstrate when it opens and closes. Learn how the thermostat controls the cooling system, common failure signs (sticking, leakage, delayed opening), quick diagnostic checks, and safe DIY thermostat replacement steps. Keywords: car thermostat, thermostat teardown, thermostat test, cooling system, thermostat replacement, engine overheating, DIY car repair.
