A vehicle’s cooling system is responsible for regulating engine temperature and preventing overheating. When this system malfunctions, it can lead to serious engine damage and expensive repairs. Recognizing common cooling system problems can help you address issues before they become severe. At ATL Total Car Care, we provide expert cooling system repair in the greater Murfreesboro area. Here are five common cooling system problems.

Low Coolant Levels

Coolant is essential for maintaining the proper operating temperature of your engine. If coolant levels drop too low, the engine may overheat, potentially causing major damage. Low coolant can be caused by leaks in the radiator, hoses, water pump, or head gasket. If you frequently need to add coolant, it’s important to check for leaks and address them promptly. Ignoring this issue can result in engine overheating and costly repairs.

Radiator Leaks and Clogs

The radiator plays a crucial role in dissipating heat from the coolant before it recirculates through the engine. Over time, radiators can develop leaks due to corrosion and cracks. A leaking radiator reduces the efficiency of the cooling system and can cause coolant loss. Additionally, radiators can become clogged, restricting coolant flow and leading to overheating. Regular radiator maintenance, including flushing the system and checking for leaks, can help prevent these issues.

Malfunctioning Thermostat

The thermostat controls the flow of coolant between the engine and the radiator. If the thermostat becomes stuck in the closed position, it prevents coolant from circulating, causing the engine to overheat. Conversely, if it sticks in the open position, the engine may run too cold. A faulty thermostat should be replaced at the first sign of trouble.

Water Pump Failure

The water pump is responsible for circulating coolant throughout the engine and radiator. If the pump fails, coolant flow is disrupted, leading to overheating. Water pump failure is often caused by worn-out bearings or a broken impeller. Symptoms of a failing water pump include coolant leaks near the pump and a whining noise. Since the water pump is a critical component of the cooling system, timely replacement is essential to prevent severe overheating issues.

Blown Head Gasket

A blown head gasket is one of the most serious cooling system problems. This occurs when the gasket that seals the engine block and cylinder head fails, allowing coolant to leak into the combustion chamber. Symptoms of a blown head gasket include white smoke from the exhaust, coolant loss, and engine overheating.
