The term has been used on this forum a lot. I thought it might have meant one thing years ago but now just means to hot soak and flush at a rad shop. I didn't think it actually might have meant to clean out the rad by running a "rod" down the core. If the rad was that bad I think replacing would be a better choice. I've never seen a clean rad shop. The one I go to is run by the son of the founder and I suspect is a future EPA super fund site. <img src="/forums/images/graemlins/cyclops.gif" alt="" />
