The viscous coupling is an important part of the car's cooling system. Every car is equipped with a cooling system, because the engine can get very hot while driving. If the engine parts are not cooled properly, this could cause overheating and engine damage.
The viscous coupling ensures that the engine is supplied with the right amount of cooling wind. The viscous coupling ensures that the radiator fan is switched on as soon as there is not enough wind. This can occur, for example, during traffic jams. In addition to switching on the fan, the viscous coupling also ensures that the fan does not switch on when the cooling of the engine is not yet required. This will occur if the car has just started and has not yet warmed up. At the moment the cooling is still superfluous.
Viscous coupling defective
When the viscous coupling is defective, you can notice this by the temperature of the engine. In the event of a defect, the coupling can no longer ensure that sufficient cooling wind is supplied. This is noticeable when driving at low speeds or in traffic jams. When you drive in a traffic jam, there will not be enough wind to cool the engine and the radiator fan must be switched on. As soon as the viscous coupling is broken, the fan will not be switched on and the engine temperature can rise. A message is often given in the on-board computer or can be read on the temperature gauge.
Is the viscous coupling broken? Make sure it is replaced as soon as possible. Failure to provide the engine with proper cooling can cause the engine to overheat and eventually cause serious engine damage.
Replace viscous coupling
You can replace the viscous coupling yourself, provided you have the correct technical knowledge. Replacing the viscous coupling also involves disassembling and reconnecting parts of the cooling system. It is very important that everything is back in its proper place and that the cooling system is working properly. Would you rather leave the job to the garage? Then make sure that you purchase the coupling at an affordable price from Winparts and deliver it to the garage yourself. If you supply the parts yourself, you often save a lot of money.
