The temperature indicator light will come on when the engine overheats.

• A. True
• B. False
• C. It comes on only when the fuel level is low
• D. It indicates oil pressure

Answer: (A)

The temperature indicator light is tied to the engine’s cooling system and will illuminate when the coolant temperature exceeds a safe limit, signaling overheating. That’s why this statement is true—the light is specifically there to warn you that the engine is running too hot. It isn’t triggered by low fuel or by oil pressure, which have their own separate warning lights. When you see the temperature light, pull over safely, wait for the engine to cool before checking anything, and check for obvious causes like low coolant or a blocked radiator or fan; if the light stays on after taking simple steps, seek mechanical help.
