its like a little plug that is made usualy of aluminum that has a little bit larger outer end on one side so then you push it in a hole it will stay tight and in place. If you ever need to pull one on a tranny (specificaly for a speedo housing) be very very careful.

Also refered to as "core plugs" or "soft plugs" They fill holes in castings that are put there to allow casting material a way out or to plug "galleys". The term "freeze plug" comes from the hope that frozen water in an ill-prepared cooling system will force them out before the block cracks from the pressure....... :whoops:

To resurrect a thread from the dead....

I'm preparing to replace the head gasket and a Ford guy on another thread offered: "otta change the freeze plugs too while ya have the head off "

I've searched around and can't find anything about replacing freeze plugs as a PM item for an 80 series.

Is this a Ford thing and is not applicable to the 1FZE?

I would not mess with the freeze plugs unless you have a confirmed coolant leak.
