Cooling System
The cooling system in your vehicle is key for maintaining the engine’s correct temperature and to prevent overheating. It circulates coolant (also known as antifreeze) through the engine, helping to dissipate heat generated during basic operation. Without a properly functioning cooling system, the engine can overheat and cause significant damage. You can find yourself with steamrolling from under your hood and stuck without a working vehicle!
Signs Your Cooling System Is Not Working
You need to have a working cooling system to keep your vehicle running. If the system isn’t working the way it should, it can lead to engine damage and even total failure, which can have you spending big money on repairs. Here are some signs that indicate your cooling system may not be working properly:
- Overheating Engine: One of the most obvious signs of a failing cooling system is if the engine temperature gauge starts rising into the red zone, or if you see the “Check Engine” or “Engine Overheat” warning lights. As annoying as this light can be, it lets you know that your engine isn’t cooling the way it should and you need to get it fixed before bigger problems happen.
- Coolant Leaks: If you notice puddles of coolant (often brightly colored green, orange, or pink) under your vehicle, it could indicate a leak in the cooling system. You don’t want to drive with a leak because there may not be enough liquid to keep the engine parts cooled down.
- Low Coolant Levels: If you consistently find that your coolant levels are low, it could mean there’s an issue with the cooling system, such as a leak or an inability of the system to circulate coolant properly. Low coolant levels can prevent proper cooling, causing the engine to overheat.
- Strange Noises from the Engine: You never want to feel like you’re in a manufacturing plant while inside your car. If you hear grinding, whining, or bubbling noises coming from the engine or radiator, it may indicate issues such as a faulty water pump, clogged radiator, or air trapped in the system. These noises can signal that the coolant is not circulating properly or there’s a problem with one of the cooling components.
- Steam Coming from Under the Hood: If you notice steam rising from under the hood, it’s a sign that the engine is overheating, and the coolant may not be functioning correctly. This could be due to low coolant levels, a failing radiator, or a blocked hose and should be addressed immediately to avoid engine damage.
