the off the shelf rad flush has citric acid as one component. any extreme, acid or base, will hurt the aluminium. copper rads can be treated with a harsher acid, or take it to a rad shop an let them do it. For the Al rad, I'd buy some rad flush and fill the out of van rad with solution and let it sit, then flush hard with water. alistair

I have a copper radiator and an aluminium one. They are both loaded with slime. I know, I can buy a new one. That's not the question now. There are many of us on the list who would like to know this. And maybe it is a good practice to rinse it sometimes, I guess. It can be done while still in the car. Then we would not have to replace it. I think of something acid or alkali kind. Maybe there is one that is already being used long time and I just don't know of. One maybe for aluminum one for others. Anyone? |
