Good quality engine coolant contains various additives that will protect the system in different ways. Over time these additives will start to break down and lose their effectiveness and at this point the performance of the cooling system components will be compromised due to factors such as corrosion or build-up of foreign particles on the surfaces of the various components. This will impair the performance of the system and may lead to more expensive repairs at a later stage.
In order to maintain the system at optimal performance levels it is recommended to replace the coolant and flush the system from time to time. Please contact your local Silverton Radiators outlet and they will gladly assist.
