If you do decide to use the citric acid, you must fill the system, run the vehicle, and drain it at least three times. It's vital to get all the acid extracted from the system prior to filling with coolant. There are some members that did this five times until they could not feel any slippery sensation in the flush water.
If you don't want to make the complete effort, it's better to forego the acid treatment.
