Few things are as stressful for drivers as seeing the temperature gauge climb into the red or spotting steam pouring from under the hood. An overheating car is not only inconvenient, but can also lead to serious engine damage if not addressed quickly. At Gab’s Auto Repair, we provide expert cooling system repair in the greater Phoenix area. Here are four common reasons that vehicles overheat.

Faulty Thermostat

The thermostat controls the flow of coolant through the engine. When working correctly, it ensures that the engine warms up efficiently and stays within a safe operating temperature range. If the thermostat becomes stuck in the closed position, it prevents coolant from circulating, causing heat to build up rapidly. Generally, a malfunctioning thermostat is relatively inexpensive to replace, but ignoring it can result in costly repairs from overheating.

Radiator Issues

The radiator is responsible for dispersing heat from the coolant, and when it isn’t functioning properly, your car can quickly run hot. Clogged radiator passages, leaks, or a failing radiator fan are all common culprits. Dirt, debris, or corrosion inside the radiator can also reduce its effectiveness. Ensuring the radiator is clean and leak-free is essential for keeping your car’s temperature under control.

Water Pump Failure

The water pump is at the heart of the cooling system, circulating coolant throughout the engine and radiator. If the pump malfunctions, coolant circulation will stop, and overheating will occur. Small leaks and whining noises are warning signs. Addressing these issues promptly helps avoid complete pump failure and a potential breakdown.

Low Coolant Levels

Coolant plays the vital role of absorbing heat from the engine and carrying it to the radiator, where it is released. If the coolant level is too low due to leaks, the engine can quickly overheat. Sometimes leaks occur in hoses, the radiator, or the water pump, which allows coolant to escape.
