Chapter 21, Problem 1RQ
What is normal operating coolant temperature?
Expert Solution & Answer
To determine
State the normal operating temperature of a coolant.
Explanation of Solution
A thermostat is referred as a temperature-controlled valve located at the engine coolant exit on most engines to control the minimum normal operating temperature. It is used to control the normal operating coolant temperature between high-temperature and low-temperature extremes.
The coolant temperature usually depends on the thermostat rating. The engines equipped with a
