Default Re: Back flushing the radiator

Ray, be sure to drive it several times during the 30 days, so it gets heated and circulated. Had mine not worked after 30 days, I would have tried an additional 30 days. After that I would have unsoldered the bottom tank and rodded it out.
Sure glad it worked out after 30 days of vinegar and removing the radiator to flush it upside down, as I didn't want to disturb an original radiator unless absolutely neccessary..
