Here are the possible causes for the radiator light to come on:
• Low Coolant Level: If the coolant level in the radiator or reservoir is low, it can cause the engine to overheat. Check the coolant level and top it off if necessary.
• Coolant Leak: If there is a leak in the cooling system, such as a broken radiator hose or a bad water pump, it can cause the coolant level to drop and the engine to overheat. Inspect the cooling system for any leaks.
• Faulty Thermostat: A malfunctioning thermostat may not allow the coolant to flow properly through the engine, causing it to overheat. Test the thermostat to see if it is working correctly.
• Radiator Fan Failure: The radiator fan helps to dissipate heat from the engine. If the fan is not working properly or the radiator is blocked with debris, the engine may overheat. Check the fan and clean the radiator if necessary.
It’s important to address the issue as soon as possible when you see the radiator light come on. Driving with an overheated engine can cause severe damage to the engine and other parts of the car, resulting in costly repairs or even a total breakdown. If the light comes on while you’re driving, pull over to the side of the road in a safe location and let the engine cool down before continuing. If the light stays on or comes back on, take your car to a qualified mechanic for diagnosis and repair.
