The purpose of a thermostat in an engine cooling system is to
A. Prevent the coolant from boiling
B. Allow the engine to warm up quickly
C. Indicate the coolant temperature
D. Pressurise the system to raise the boiling point
Answer: Option B
Solution (By Examveda Team)
When the engine is cold, the thermostat is closed and prevents coolant from flowing into the engine and allows the engine to warm up.Once the engine has warmed, the thermostat will open and allow coolant to flow and cool the engine when it starts to get too hot.
This function is vital for optimal engine performance.
