Water distribution tube
Posted by Owen_Dyneto On 2009/6/9 16:08:37
Many writers on these pages have spoken often of the wisdom of, when the water pump is removed on many of the in-line engines, going a step further and removing the radiator so the water distribution tube can be removed, inspected, cleaned and/or replaced.
The following picture demonstrates this need vividly. I've never seen a Packard tube that wasn't brass; this one was steel like Chrysler used, perhaps an aftermarket replacement from Dorman or similar. In any case it's condition is obvious and I consider it a miracle there were no engine block cracks at the exhaust valve seats. And consider that you can't install a new tube w/o removing the old one, and it's a long, narrow and blind hole with no other access. It was MANY hours of fishing with rods and hooks to get the fragments out.
