What is the main purpose of the cooling system?

This is a system of components responsible for maintaining the operating temperature of the drive unit within the optimal range.

How does a car radiator work?

The radiator extracts heat from the coolant and releases it to the environment, assisted by a fan and air flow.

What does a thermostat do in a cooling system?

The thermostat regulates the moment when coolant begins to circulate through the radiator, allowing the engine to reach operating temperature faster.

How do you know if your water pump is faulty?

Symptoms include fluid leaks around the timing belt, unusual operating noises, and increased engine temperature.

Are cooling parts the same for all car models?

No – even within a single brand, there are differences in parameters and construction. Therefore, it's worth matching the part by its VIN or catalog number.

What are the symptoms of a damaged engine temperature sensor?

These may be incorrect readings on the dashboard, a problem with starting the fan or error messages in the on-board computer.

Are used coolers safe?

Yes – provided they have been tested for leaks and are free of mechanical damage. At Global Parts, every part undergoes quality control.

At the Global Parts automotive store, we offer a wide selection of original used car parts, including engine cooling components, for many popular car brands such as BMW, Mini, Mercedes, Audi, Volkswagen, and others.
