What Causes the Car Temperature Gauge to Light Up?

[BriellaFitz]

When the car temperature gauge lights up, it indicates a fault in the engine's cooling system. The temperature gauge will illuminate under two circumstances: when the vehicle is low on coolant, or when the engine is overheating. If the temperature warning light comes on, the first step is to pull over to a safe location and check if the coolant level is low. If it is, you should top it up and inspect for any leaks. If leaks are found, they should be repaired as soon as possible. If the coolant level is normal, the issue is likely engine overheating, and you should seek professional assistance to diagnose and fix the underlying problem. Most vehicle temperature gauges are analog, with the needle pointing within the normal range (around 95°C) when the temperature is optimal, staying clear of the red zone.
