The 356 uses the same water dist tube that the other eights made thru 54 used. Someone mentioned in another post that some of the senior pre 1940 eights did not have one.

O_D has advised using oxalic acid for cleaning many timeshttps://packardinfo.com/xoops/html/modules/newbb/viewtopic.php?post_id=162991#forumpost162991 IIRC in some of the discussions believe it was mentioned that was Packard approved and the same item as one of their radiator treatment products. I would think might be a gentler and safer treatment than muriatic acid.
