Engine Overheating in Cold Weather: Why It Happens

Engine Overheating in Cold WeatherEngine overheating isn’t solely a summertime occurrence. Even with the nippy fall weather in Monroe, car engines can and do incur damage due to excess heat. We’ll explain the common causes of engine overheating in cold weather as well as the remedies for addressing the issues.

What Causes Engine Overheating in Cold Weather?

Numerous mechanical issues can cause engine overheating. These issues have zero or little to do with blistering weather.

1. Insufficient Coolant Levels

Pop open the hood and check the anti-freeze level. Low coolant levels may be due to a leak caused by a loose radiator cap, a split hose in the radiator, or an opening in the head gasket. Bring your vehicle to an auto repair shop to pinpoint the source of the leak.

2. Broken Radiator Fan

The radiator fan blows cool air into the radiator and keeps the engine temperature at an acceptable level. A broken radiator fan can be due to a number of factors, such as worn fan wires, a blown fuse, or broken temperature sensor. Diagnosis and repairs require professional auto servicing. Our online special offer provides discounts for such services.

3. Broken Thermostat

The car’s thermostat monitors the internal temperature. When the heat reaches a specific threshold, the thermostat relays the message to the computer, which opens a chamber to allow the coolant to flow into the system. A broken thermostat may not send the signal to open the chamber. With a bad thermostat, the car will run fine before abruptly experiencing a major temperature spike.
