What are the Signs of Engine Overheating?

Car overheating is a concerning problem, especially during summers and mid-winters, due to various fluctuations in the temperature. When you put extra strain on your car’s cooling or heating system, it affects your engine, causing car overheating. Follow along with Budds’ Chev as we take a closer look at some potentially crucial information.

To protect your car from severe engine damage due to overheating, you’ve got to keep an eye on potential signs and symptoms, such as:

  • Check the engine temperature gauge symbol on your car’s dashboard. If it has turned to H or red, this indicates engine overheating. The gauge symbol and functioning may vary from car to car and model to model, so it’s better to stay informed with the help of the owner’s manual. 
  • If you notice steam or smoke coming out of the car’s bonnet, it’s because of overheating. 
  • Notice any peculiar smell coming from the car; it could be from the leaking coolant or engine oil.

What Causes Car Overheating Problems? 

Following are some of the significant reasons that may result in car overheating:

1. Car Water Pump

A water pump contains a fan-like blade called an impeller that pushes and spins the coolant through the cooling system. If a car’s water pump gets damaged or broken, it affects the functioning and circulation of the coolant, leading to engine overheating. 

2. Leaking Coolant

Coolant leakage can be both external and internal, and it can leak from different components and locations of a vehicle, including a water pump, radiator, hoses and thermostat, head gasket and cracked engine block. A low coolant level can cause car overheating. 

3. Coolant Temperature Sensor

Modern Chevy, Buick and GMC vehicles come equipped with coolant temperature sensors that maintain a moderate temperature. The sensor relies upon engine coolant temperature to turn the cooling fan on and off. When these sensors fail to read the data, it results in engine overheating.
