Engine Cooling System – What You Need to Know

The engine cooling system is one of the essential components ensuring your vehicle runs smoothly. In this category, you will find a wide selection of radiators, thermostats, water pumps, and other parts necessary to maintain the optimal working temperature of your engine. Regular inspection and replacement of cooling system elements guarantee driving safety, extend the engine's service life, and lower your car's running costs.

How does the cooling system work?

The main task of the cooling system is to dissipate excess heat generated during engine operation, preventing overheating. Coolant circulation, driven by the water pump and managed by the thermostat, maintains constant operating temperature. The radiator releases heat into the environment, with the fan supporting this process during stationary or traffic conditions.

Most common cooling system failures

Typical problems include: radiator leaks (coolant fluid leaks), water pump failure (noisy operation, leaks, engine overheating), thermostat malfunction (stuck open or closed, which results in underheating or overheating), and worn hoses and fittings. Warning signs include rising engine temperature, coolant stains under the car, or reduction of the fluid level in the expansion tank.

When to replace the cooling system parts?

Regularly check the radiator, coolant level and condition, water pump efficiency, and thermostat function. Preventive replacement of the water pump is recommended during timing belt service. Any leaks or signs of engine overheating require immediate diagnosis and repair.

Frequently Asked Questions

• How to identify a faulty thermostat?
Erratic temperature readings – the engine warms up slowly or quickly overheats.
• When should coolant be changed?
Typically every 3-5 years or as recommended by the vehicle manufacturer.
• Is it safe to drive with a damaged radiator?
Absolutely not – it could cause serious engine damage.
• How much does water pump replacement cost?
Costs depend on the car model and selected pump, but regular replacement is cheaper than repairing failure damage.
