Freeze Plug Replacement

Alright, my freeze plug that is to the passenger side of the timing chain is leaking.

Anyone replaced this w/o pulling the timing chain cover?

I have heard dent puller to pull the plug out, also tap the top with screw driver, rotate the plug, then pull out with plyers. I dont think a dent puller will fit. Any tips here?

Anyone know a part # or size that I need for this?

You probably could pull it without pulling the cover...

As far as pulling it out, they can sometimes be a PITA. Remember they are a PRESS FIT.

You might try using a ratchet extension, and tap one side of the 'lip' of the plug. If you can turn it cockeyed, then you can pull it out with pliers.

You might also drill a hole in the center of it, and try using a pilot bearing removal tool to pop it out.

Take a strong, self tapping screw, screw it in the center, and pull it out.



Those are just a couple of ideas I came up with...

Also, not sure about size (just measure it) but use a brass one, if you can, when you replace it. Much better plug.

Didnt know brass ones were better, will look for them.

Also screw driver might pierce the steel, something blunt would be less likely,thanks for that idea.

piolit bearing tool, dont have one of them, that I know of.

Doward, can you do me a favor. Since you have an engine out, and no accessorys on the front of the engine, can you measure it for me?

Just a HAIR under 1.5"... so I'm going to say a 1 7/16, or a 1 3/8s

Just pick up all the sizes they have up to 1.5"

Freeze plugs

My company manufactures plugs for one of the major small parts companies, for rebuilders and the DIY'ers. Advance, Autozone, etc. all have interchange books to get the right set. Best way to remove is with a dent puller. If you knock one end in, make sure you don't lose it inside. Some people coat outside with RTV sealant before install and some don't- don't know which is best. If anyone else is doing the job themselves, Dorman/Motormite has a style of plug called a pilot seal (tm) and it is easier to install with out it cocking sideways.
