Super Radiator Flush (1201)
See What Our Customers Are Saying View More Testimonials
I tried another brand's product to flush my very nasty radiator. Didn't work, my system was still dirty after the flush. Counterperson at AutoZone said to try this. Took it home, and it cleaned everything out super well in one step. Not all products work the same. I'd choose this one again if I needed another flush. - George, J. - Harrisburg, PA
