An overheating engine is a serious problem that can quickly lead to costly damage if not addressed right away. When your car’s temperature gauge climbs into the red, it’s a clear warning sign that something is wrong within the cooling system. Understanding the most common causes of overheating can help you identify the issue early and get it repaired before it leads to engine failure. At Presto Auto Electric, we provide expert cooling system repair in the greater Carson City area. Here are four common reasons why cars overheat.

Faulty Thermostat

The thermostat controls the flow of coolant between the engine and radiator. When working properly, it opens and closes at the correct temperature to keep the engine within a safe range. If the thermostat becomes stuck closed, coolant can’t circulate, causing the engine to overheat. This is a common issue that often goes unnoticed until the temperature gauge starts climbing unexpectedly.

Low Coolant Levels

Coolant plays a crucial role in regulating your engine’s temperature by absorbing and dissipating heat. If your coolant level is too low due to a leak or lack of maintenance, the engine can’t stay cool. Common leak points include hoses, the radiator, and the water pump. Without sufficient coolant, heat builds up quickly, leading to overheating and potential engine damage if ignored.

Malfunctioning Water Pump

The water pump is at the heart of the cooling system, pushing coolant through the engine and radiator. If it fails, coolant circulation is disrupted. Without proper flow, heat gets trapped inside the engine, causing the temperature to spike. A whining noise or coolant leak can be warning signs of a failing pump.

Clogged or Leaking Radiator

The radiator releases heat from the coolant before it cycles back through the engine. Over time, radiators can become clogged with debris that blocks the flow of coolant. Leaks can also reduce cooling efficiency. When the radiator can’t do its job effectively, the engine temperature rises, leading to overheating, especially during hot weather or heavy driving conditions.
