On a 6 ,how do you get the suckers out and how are they put in. With an epoxy?

A screwdriver (big) and a hammer (big) work wonders for the removal.

Hylomar works going back in, after you clean the block well from any crud.

I would use brass cups. Actually, I did use brass cups on my new engine and have done so over the years on every engine that I could get them for.

The originals start out domed, and get flattened in place, which causes them to expand and lock into position.

This is one of the few places where I prefer Permatex #3 instead of Hylomar. But I have used epoxy to reinstall them, when someone carelessly nicked the block taking the old ones out.

Give that man a CEE-GAR!!! :iagree:

Prying 'em out can be a real exercise in self-inflicted pain, so just be judicious about HOW you have your hands positioned... don't ask. :shocked:

OK, Randall. I can agree with that. P-Tex #3 is fine too.

Years ago, the old stand by of Indian Head Shellac graced many a freeze plug going into a block.

Where does a man with gobs of money find these brass ones?

Dorman Products at NAPA or your local parts store.

And they are not expensive. Maybe 10% more than the steel.

If this is correct and it may not be, (I'm going from an old tattered list) these are the numbers that I think you need. Keep in mind, that the correct depth is important, so you will need the (SC) shallow cup, which I know these are where noted.

Dorman Numbers:

565-017 - 1.0" Front uses (1) $1.09

565-024 - 1.25"(SC) Rear uses (3) $1.39

565-025 - 1.375" (SC) Side uses (5) $2.19

565-069 - 2.0" (SC) Rear Cam? uses (1) $2.19

The head also uses 1.25"

If you run into trouble finding them, I have some spares.

Thanks Paul- I passed this info on to a friend who is in one of those decade long body offs.

When it comes to the plugs on the drivers side of the engine. Don't hit it along the bottom edge. You'll be banging away until the cows come home. There is a raised ridge of the block behind those plugs. Hit the top half and they will pivot right out.
