What is the role of a water pump?
When operating, a thermal engine is subjected to very high temperatures. To protect it from overheating and frost, it is equipped with a cooling circuit to keep it at a regular operating temperature.
An important part of the cooling system is the radiator, but it would not be efficient without the action of the water pump. The role of the water pump is to ensure that the coolant circulates properly to the radiator so that it can cool down and prevent overheating. It is therefore an important part of the cooling circuit.
How do water pumps get damaged?
The use of used coolant can adversely affect the proper operation of water pumps. A coolant with a lower pH will increase its acidity and therefore its corrosiveness. This corrosion causes solid particles to detach from the metal surfaces of the cooling system which destroy the mechanical seals of water pumps.
The risks are either a failure of the water pump or the appearance of leaks. In both cases, these two problems can have serious consequences for the engine, even leading to its breakage.
How to provide protection for water pumps?
For better protection of water pumps, it is advisable to regularly check and replace the coolant in a vehicle. This replacement maintains the correct pH level so that the coolant is not too corrosive and does not damage the metal parts of the cooling circuit and therefore the water pumps.
How do I replace the coolant?
For fast and efficient coolant replacement, the Flash Cooling® station is the ideal tool. By connecting directly to the vehicle’s expansion tank, draining, purging and replacing the coolant can be done in minutes and without disassembly.
