3 Common Signs of a Failing Cooling System
Your car’s cooling system plays a critical role in keeping the engine at the right operating temperature. It circulates coolant through the engine and radiator to prevent overheating and protects the engine from serious damage. When the cooling system begins to fail, the results can be very costly if ignored. At Integrity Fleet Service, we provide expert automotive cooling system repair in the greater Gilbert, AZ area. By recognizing the signs of cooling system trouble early, you have a better chance of avoiding breakdowns and extending the life of your vehicle.
Rising Temperature Gauge
One of the clearest signs of a failing cooling system is a temperature gauge that climbs higher than normal. If the needle frequently moves into the red zone or fluctuates unexpectedly, it means the cooling system is struggling to regulate engine heat. This could be due to a coolant leak, clogged radiator, or faulty thermostat. Ignoring the warning can quickly lead to engine overheating.
Coolant Leaks
Coolant leaks are another common indication of cooling system trouble. If you notice bright green, orange, or pink fluid (your cooling might be a different color) under your vehicle, then there could be coolant escaping from a hose, radiator, or water pump. Low coolant levels caused by leaks prevent the system from functioning properly, increasing the risk of overheating. Even small leaks should be addressed right away to prevent major damage.
Sweet Smell or Steam
A failing cooling system often makes itself known through unusual smells and/or visible steam. A sweet, syrupy odor inside or outside the car commonly points to leaking coolant. Steam rising from under the hood while driving is a sign that the engine is dangerously hot. If you see steam, it’s best to pull over safely as soon as you can—and then let the engine cool before investigating further.
