I just recieved a book by Richard Newton called How to Restore Your Corvette 1968-82. In it he talks about cleaning out the cooling system and say to drain it out and refill it it with plain water and add some dish washing detergent to the system and drive for a couple of weeks. He says that the combination of the high engine temperture and the dish detergent would clean up the system better than any commercially available system flushes and won't eat holes in your radiator like regular radiator flush does. Then he says to drain it again and if it's not clear fill it with water again and add the detergent again, and drive for another week. He says to do this until it drains out clean without any dirt coming out of the system and then fill it with a 50/50 mixture of anti-freeze and water. Has anyone heard of this or tried it? I would think that the dish washing detergent would do damage to the water pump bearing by cleaning out the lubricant in it. Am I wrong or is this method safe to do to your car? :confused
