Your vehicle's cooling system plays a crucial role in maintaining the optimal operating temperature of the engine. A malfunctioning cooling system puts your car at serious risk of overheating, which can result in severe engine damage and costly repairs. This makes it important to get to the shop at the first sign of a cooling system problem. At Auto Science, we provide expert cooling system repair in the greater Lewisville, TX area. Here are five symptoms of cooling system trouble.

Overheating

Perhaps the most obvious sign of a cooling system problem is an overheating engine. If you notice your temperature gauge climbing into the red zone or see steam escaping from under the hood, it's a clear indication that your cooling system is struggling. Overheating can be caused by a variety of issues, such as a faulty thermostat, a malfunctioning radiator fan, or low coolant levels.

Coolant Leaks

Keep an eye out for any puddles or stains of bright-colored fluid (commonly green, orange, or pink) beneath your parked car. Coolant leaks can occur due to a damaged radiator, a cracked hose, or a malfunctioning water pump. 

Low Coolant Level

A sudden drop in your coolant level may indicate a leak or an internal issue. Low coolant levels can lead to inadequate heat dissipation, causing the engine to overheat.

Unusual Engine Sounds

A malfunctioning cooling system can result in strange noises coming from your engine. Gurgling or bubbling sounds may indicate air pockets in the cooling system, while grinding noises might suggest a failing water pump. If you notice any unusual sounds while driving, it's important to bring them to the mechanic’s attention ASAP.

Dashboard Warning Lights

If your dashboard displays a warning light—such as the coolant warning light or the check engine light—it's crucial not to ignore it. An illuminated warning light is often an early indicator of a developing problem. By addressing it promptly, you’ll have the best chance of avoiding a more serious issue.
