Farking freeze plugs!

What it is?

Universal expanding core plug. Just get the right size, poke it in the hole and tighten the nut. Meant for temp repairs but apparently last ok.

My recipe for successful frost plugs.

Get the hole really clean with Emery tape.

Put blue lock tight around the outside of the plug.

Find a socket that is a loose fit inside the cup of the plug.

Tap it in. Hammer on its side if required, add socket extensions if required.

 

Got a picture of where you are trying to work?

My recipe for successful frost plugs:

New coolant every few years to stop stuff corroding in the first place

The hole is super clean, new rotor housings, have put a generous smear of loctite pipe sealant in there and have been using socket like you describe but hammer just bounces off, if i had a lathe i would take a couple tenths of mm off of the plugs they seem way too tight. Can take photo tonight

I think I'd make a plate with holes drilled to suit inlet manifold threads on block, have this standing ~2"? off the flange with some long bolts, then add a threaded hole in line with where the frost plug needs to go, then put bolt with lots of thread thru this hole and a socket on the end with the frost plug, turning the block into a press... long winded way to get there, but ya gotta do it the long way somtimes!

Are you sure they're the right size? I've always found frost plugs fairly easy to install..

Shit thats a good idea.

I should probably check this yeah... 

[oldrx]

The old measure before starting to bash method might have been the way to go, plug is about 0.7mm bigger than hole

[oldrx]

What OD should i aim for, take 0.5mm off leaving it over by 0.2mm ish, should interference fit its self in there at that size?

[Valiant]

is it possible you're trying to fit a 20mm plug to a 3/4inch hole.

I know its Japanese but they do use odd sizes some times.

[oldrx]

Mmmm not sure how they got the hole that size, bit big for 3/4 i would think possible though i guess, would be interesting to measure some 3/4 plugs if they are oversize as much as my "20mm" plugs they may be perfect, may get some and check. Mostly the trouble i think is that its a coolant port to heat inlet manifold i.e. never intended to have a plug so they didnt need to care about exacting dims.

That will be the issue I'd say.
