Lowell's Auto Repair Provides Cooling System Repair Services
The cooling system in your car is responsible for keeping the engine operating at a safe temperature by transferring heat away from the engine and dissipating it into the surrounding air. Here’s how it works:
Coolant: The cooling system uses a liquid called coolant, which is typically a mixture of water and antifreeze. The coolant circulates through the engine block, absorbing heat from the engine and carrying it to the radiator.
Radiator: The radiator is a heat exchanger that is usually located at the front of the car. It has a series of tubes that are surrounded by fins, which help to dissipate heat into the surrounding air as it passes through the radiator.
Water pump: The water pump is responsible for circulating the coolant through the engine and radiator. It is usually driven by a belt that is connected to the engine’s crankshaft.
Thermostat: The thermostat is a temperature-sensitive valve that controls the flow of coolant through the engine and radiator. It opens and closes in response to changes in engine temperature, ensuring that the engine is kept at the correct operating temperature.
Cooling fan: The cooling fan helps to draw air through the radiator, which helps to dissipate heat more quickly. In most cars, the cooling fan is electric and is controlled by the engine’s onboard computer.
If any part of the cooling system fails, it can cause the engine to overheat, which can lead to serious damage or even engine failure. Some common signs of cooling system problems include:
- The temperature gauge on the dashboard reads higher than normal.
- Coolant leaks underneath the car or in the engine bay.
- The heater in the car doesn’t work properly.
- There is steam coming from under the hood.
If you notice any of these signs, it’s important to have your car’s cooling system inspected by a qualified mechanic. Regular maintenance of the cooling system, such as replacing the coolant and flushing the system, can also help prevent problems and extend the lifespan of the engine.
