Thermostats and housings in the engine cooling system – reliable operation in all conditions
How do thermostats work and what are the housings in cooling systems made of?
Thermostats and housings are key components of the cooling system, controlling coolant flow and maintaining optimal engine operating temperatures. Their efficiency ensures engine performance, reduces fuel consumption, and protects against overheating. At Global Parts, you'll find a wide selection of used car parts. , including thermostats and housings, ideal for BMW , Audi , Mercedes , Volkswagen , Mini and others .
Definition and principle of operation of a thermostat
A thermostat is a thermal valve that opens at a precisely defined temperature (usually between 85°C and 95°C ) and allows coolant to flow into the radiator. In the BMW M57 engines used in BMW E60 models, the popular TH580 thermostat begins to open at 88°C, ensuring the ideal balance between rapid engine warm-up and maintaining optimal operating temperature. In Audi A4 B8 models, the typical thermostat opens slightly earlier – at 87°C – due to different cooling system characteristics.
Construction and materials of thermostat housings
Thermostat housings are most often made of high-strength plastics or aluminum. Modern solutions combine these materials, ensuring lightness, corrosion resistance, and a perfect fit in the mounting socket. Premium vehicles such as BMW and Mercedes also use components with silicone seals, which maintain a tight seal even at pressures of up to 1.5 bar .
What functions do thermostats and housings perform?
Thermostats and housings play a key role in regulating engine operating temperature: Coolant flow regulation – The thermostat opens and closes the coolant circuit depending on the engine temperature. Faster engine warm-up – The thermostat maintains the coolant in the engine until it reaches the optimal temperature, which improves engine efficiency, especially in cold weather. Overheating Protection – A functioning thermostat prevents the engine from overheating by directing coolant to the radiator. Thermostat housings – Ensure tightness and stable mounting of the thermostat in the cooling system.
Advantages of an efficient thermostat
A properly functioning thermostat ensures optimal engine performance, reducing fuel consumption by up to 5–7% and reducing exhaust emissions. By maintaining a stable operating temperature, engine oil maintains its lubricating properties, resulting in longer engine life.
Why is it worth taking care of thermostats and housings ?
Worn or damaged thermostats and housings can lead to serious cooling system problems. Typical symptoms include: Engine Overheating – A damaged thermostat may not open the circuit, leading to an increase in engine temperature. Warm-up too slow – A thermostat failure can cause a continuous flow of coolant, which increases engine warm-up time. Coolant Leak – Leaks in the thermostat housing can lead to leaks and a drop in coolant level. At Global Parts, we offer original used thermostats and housings that have undergone extensive quality testing, ensuring their durability and reliability.
Typical symptoms and possible causes of thermostat failures
| Symptom | Possible cause | Recommended action |
|---|---|---|
| The engine is overheating | Thermostat does not open | Replacing the thermostat |
| The engine takes a long time to warm up | Thermostat stuck in the open position | Inspection or replacement |
| Coolant leak | Leaking thermostat housing | Checking the gasket or replacing the housing |
| Temperature fluctuations | Dirty cooling system | Coolant replacement, system flushing |
How to choose the right thermostats and housings ?
When selecting thermostats and housings, there are several key aspects to consider: Vehicle-specific fit – Every cooling system has its own specific technical requirements. At Global Parts, you'll find thermostats and housings perfectly suited to BMW , Audi , Mercedes , Volkswagen , Mini , and more . Technical condition – Used thermostats and housings should be free from mechanical damage and tight to prevent leaks. Opening Temperature – Make sure the thermostat opens at the correct temperature recommended by the vehicle manufacturer.
Compatibility and installation
The BMW E60 thermostat with the M57 engine requires a TH580 component, which is also compatible with some versions of the BMW 530d and X5 E53. The A4 B8 thermostat, on the other hand, fits the 2.0 TDI and 1.8 TFSI engines, and replacing it is relatively simple – simply disconnect the intake hose, drain some of the coolant, and install a new thermostat with a new gasket.
Why choose used thermostats and housings ?
Used car parts , such as thermostats and housings, are a practical solution that allows you to save money while maintaining high quality. By choosing used thermostats and housings, you benefit from: Lower costs – Used components are much cheaper than new ones, but offer equally high quality. Ecology – Recycling car parts supports environmental protection and reduces waste. A wide range – In our store you will find thermostats and housings for the most popular car brands.
Comparison – Used vs. New Thermostat
| Characteristic | Used thermostat | New thermostat |
|---|---|---|
| Price | up to 60% lower | full list price |
| Efficiency | 90–100% after quality testing | 100% |
| Ecology | supports the recycling of parts | new production |
| Availability | immediate | sometimes limited |
How to take care of thermostats and housings ?
To ensure that thermostats and housings function reliably for a long time, it is worth following a few rules: Check the condition of the thermostat and housing regularly, especially if you notice problems with the engine operating temperature. Change the coolant according to the manufacturer's recommendations to prevent scale and contaminants from building up in the system. Monitor the coolant level – a sudden drop may indicate a leak in the thermostat housing. If you need a replacement, you'll find the right used car parts at Global Parts that will restore full functionality of your cooling system.
Practical tips
When installing a new thermostat, always replace the gasket and check that the coolant lines are clean and unobstructed. For BMW E60 or Audi A4 B8 models, it's also recommended to bleed the system after replacement to prevent air bubbles from forming, which can disrupt fluid circulation.
FAQ - Frequently asked questions about thermostats and housings in the car's cooling system
| Question | Answer |
|---|---|
| What is the function of a car thermostat? | A thermostat is a component of the cooling system that regulates the flow of coolant depending on the engine temperature. |
| What does the thermostat housing provide? | The thermostat housing is the part that houses the thermostat itself. It ensures the system's tightness and stable mounting of the element. |
| What does the term "M57 thermostat" mean? | The M57 thermostat is a model designed for the BMW M57 diesel engine – used in, among others, the BMW E60, E39 and X5. |
| How to recognize a faulty thermostat? | Symptoms include temperature fluctuations, overheating or engine warming up too slowly. |
| Does the BMW E60 thermostat fit other models? | Yes, some thermostat versions, e.g. TH580, are also compatible with the BMW 530d, 525d and X5 E53. |
| How often should you replace your thermostat? | It is recommended to check it every 60,000–80,000 km or whenever the coolant is changed. |
