If the temperature light comes on in your vehicle, what should you check?

When the temperature light in a vehicle illuminates, it typically indicates that the engine is overheating. One of the primary causes for an engine to overheat is a lack of sufficient coolant. Therefore, checking the coolant levels is essential because coolant helps regulate the engine's temperature by absorbing heat and dissipating it through the radiator. If the coolant is low or absent, it can lead to severe engine damage.

Maintaining proper coolant levels ensures that the engine operates within its designated temperature range, thereby preventing overheating and prolonging the life of the vehicle. It's also important to inspect for any leaks in the cooling system, as this could contribute to reduced coolant levels.

While checking oil levels, battery status, and tire pressure are all important routine maintenance tasks for a vehicle, they are not directly related to the specific function of temperature regulation.
