This is the coolant temperature warning indicator. Here are the detailed explanations: 1. Introduction: The coolant temperature indicator is a bimetallic strip sensor switch screwed into the engine block water jacket. This switch controls the red warning light (high-temperature indicator) on the instrument panel. Within normal operating temperature range, the switch contacts remain open and the indicator stays off. When coolant temperature exceeds normal levels, the switch arm contacts close, illuminating the red warning light. 2. Function: This indicator displays the temperature of engine coolant. When turning the ignition key for vehicle self-check, it will light up for several seconds then turn off. If the coolant temperature light remains illuminated, it means the coolant temperature has exceeded specified limits. You should immediately stop driving until the temperature returns to normal and the light turns off.
