In my opinion, the citric flush is the biggest waste of money. I dont see why you cant flush the cooling system like all other cars on earth are done. I have always used standard green coolant and have never had a single issue. The only thing I have ever done is change coolant (every 25,000) and replace the rad. cap.

I don;t see or understand the purpose of the citric flush. What exactly is the textbook purpose?

Thanks!
