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.

Engine cooling system parts – proven solutions for your car

Cooling components for BMW, Audi, Mercedes and others – guaranteed quality and fit

The engine cooling system is one of the most important systems in any vehicle, responsible for maintaining optimal operating temperature of the engine. It prevents engine overheating and protects against costly breakdowns. At Global Parts, you'll find a wide selection of used car parts. for cooling systems such as radiators, fans, water pumps, and thermostats. Our range of cooling systems is tailored to brands such as BMW , Audi , Volkswagen , Mercedes , Mini, and many others, so you'll find the perfect solution for your vehicle.

How does the engine cooling system work?

The engine cooling system is a complex system responsible for removing excess heat generated during engine operation. Its key components include:

- Fans and fan housings – They are responsible for air flow and radiator cooling.
Cooling system hoses and lines – They transport the coolant between individual system components.
Water coolers – Key elements responsible for collecting heat from the engine and dissipating it.
Thermostats and housings – Regulate coolant flow, maintaining optimal engine temperature.
Water pumps – They drive the circulation of coolant, enabling efficient engine cooling.
Oil coolers and hoses – They help maintain optimal oil temperature, reducing oil degradation.
Expansion tanks – They are responsible for maintaining the proper coolant level and compensating for changes in liquid volume.
Overlays – Protective elements of the cooling system, increasing its durability.
Clamps and mounting parts – They enable stable mounting of cooling system components.
Fan blades – They support cooling by increasing airflow.
Fan clutches – Regulates the fan speed depending on the engine temperature.
Fan and blower motors – They are responsible for the operation of the fan, ensuring proper cooling.
Temperature sensors – Monitor engine and coolant temperature, sending information to the controller. All of these components work together to keep the engine at a stable operating temperature, protecting it from overheating or overcooling.

Parameters of cooling systems in cars

The engine cooling system in a passenger car operates at temperatures ranging from 85°C to 105°C, depending on the vehicle model and manufacturer's specifications. Modern radiators are typically constructed of aluminum, which provides better thermal conductivity and lower weight. Coolant flow requires adequate pressure—typically between 0.9 and 1.5 bar —which is maintained by the reservoir cap. Proper operation of this system is crucial to maintaining engine efficiency.

Why is it worth taking care of the engine cooling system?

Regular maintenance and replacement of worn cooling system components is essential for long and reliable engine operation. A neglected system can lead to:

Engine overheating, which increases the risk of serious damage.
Coolant leaks that may reduce cooling efficiency.
Higher repair costs resulting from failures caused by a faulty system. At Global Parts we offer genuine used car parts, which undergo detailed quality tests, ensuring their reliability.

The most common cooling system components and their roles:

System element	Function	Typical symptoms of damage
Cooler	Heat removal from the fluid	Fluid leak, temperature rise
Water pump	Coolant circulation	Loud operation, engine overheating
Thermostat	Fluid flow regulation	Heating too slowly or overheating too quickly
Temperature sensor	Temperature monitoring	Incorrect readings, computer error
Fan	Forcing air flow	No cooling when stationary

How to choose the right parts for your cooling system?

When deciding to purchase parts for the cooling system, it is worth paying attention to several key factors:

Vehicle-specific fit – Every car make and model has its own technical specifications. At Global Parts, you'll find parts for BMW , Audi , Volkswagen , Mercedes , Mini, and many more.
Technical condition – Used parts, such as radiators or water pumps, should be fully functional and ready for further use.
Radiator type – Depending on your needs, you can choose standard, intercooler or radiators dedicated to sports vehicles.

Compatibility examples

When choosing cooling system parts, it's worth considering compatibility with other components. For example, a radiator for a BMW 3 Series (E46) can be fitted to several engine variants – both petrol and diesel – but the water pump will have different part numbers depending on the engine capacity. Similarly, the Audi A4 B8 uses several types of thermostats, varying in opening temperature range (from 87°C to 95°C ).

Why choose used cooling system parts?

Car parts for the cooling system is a solution that combines high quality with savings. Why is it worth considering?

Lower costs – Used radiators, water pumps and thermostats are much cheaper than new ones, but offer just as high quality.
Ecology – By choosing used car parts, you support recycling and reduce the amount of automotive waste.
Wide range – We offer parts for the most popular car brands, so you can easily find the right components for your car.

How to take care of the engine cooling system?

To keep your cooling system running smoothly for a long time, it is worth remembering a few rules:

Regularly check the coolant level and quality – contaminated or low coolant levels can lead to engine overheating.
Check the condition of the radiator and pipes – leaks or damage may reduce cooling efficiency.
Change the coolant according to the manufacturer's recommendations – this is the key to keeping the system in perfect condition. If you notice any problems, you'll find the right used car parts at Global Parts that will help restore your vehicle to full working order.
