Engine Cooling System — Design Description The cooling system ensures the correct operating temperature of the engine. This system consists of a series of units, which include a radiator, a thermostat,...
Parts of the engine cooling system Water pump. The so-called centrifugal pump, which ensures constant circulation of the coolant. Depending on the engine, the pump is driven by a toothed or...
Coolant — basic information The coolant consists of a mixture of anti-freeze and anti-corrosion agents (antifreeze) and water. The anti-corrosion agent, which is part of the coolant,...
Checking the tightness of the cooling system 1. Are the water hoses to the radiator, engine and heating system sealed? 2. The condition of the hoses can be determined by compressing them. Replace stiff,...
Checking and topping up the coolant 1. It is best to check the coolant level when the engine is cold, as in this case there is practically no pressure in the cooling system. 2. When the engine is...
Coolant replacement 1. Use the expansion bank cap to depressurize the cooling system, then remove the cap. Take care when the engine is hot: risk of scalding! 2. Remove the...
Pouring antifreeze into the cooling system For reliability, even in summer, a mixture containing at least 40% antifreeze should be used. However, if you often add only water, then the concentration of...
Dismantling and checking the thermostat If the engine overheats while driving due to a malfunctioning thermostat, either tow the car or remove the thermostat. Of course, before removing the...
Faulty radiator fan Fans of the cooling system are connected only at high loads. Therefore, in the event of a fan defect, it is not necessary to stop the movement at all. Let the...
Dismantling and installation of the radiator Before changing the radiator, it should be pressure tested in the workshop. Specialist workshops are able to fix small leaks, so you may not have to change the...
Replacing the cooling system hoses If the coolant hose breaks on the way, the leak can be temporarily sealed with adhesive tape. To be safe, open the cap of the expansion tank one turn, in which...
