If you have bacteria in your coolant system, try using a cleaner which is added 24 hrs to the coolant prior to it being replaced. This will clean your coolant system (coolant system includes pump, pipes, etcc... not only your sump) and kill all the bacteria present in your coolant system. Your coolant supplier should be able to supply you with this system cleaner.
Another important aspect of coolant maintenance is the usage. Do not leave it for long periods without being used. If possible, use it on a daily basis, for example, starting the coolant pump for 30 min daily. |
