1. Tech A states thermostats in automotive engine are used to adjust the temperature of the engine. Tech B states radiators absorb heat from the air to keep the engine warm. Which Tech is correct?

• TECH A

• TECH B

• BOTH TECHS

• NEITHER TECH

The function of a thermostat is:

• uses an impeller to force coolant through the engine coolant passages.

• stays closed until operating temperature is reached, then allows coolant flow

• stores coolant

• primary heat exchanger for the vehicle engine

If the thermostat does not open, the engine will typically:

• turn off

• overheat

• lose oil

• leak coolant

Tech A states the thermostat temperature can be adjusted to suit operational demands. Tech B states the thermostat is necessary for a vehicle to maintain operating temperature as designed.
