Ball pean right to the middle.

I'll put up a pic next time i visit the engine refreshing plant (machine shop)

Zum, It doesn't show overlap very well but gets the point across, of securing the plug in place to ensure accidental blowout doesn't happen

So, It's a matter of getting it in with minimal fuss, then hitting it in the center to force push outwards into the block?
What could I use to hit the center?

Yeah, I didnt really have a choice unfortunately. The shop I took it to took all the plugs out automatically before hot tanking it.

Usually have to dress the edge of the hole where it's been peened over before you fit the new cup or you risk damaging it's edge.

Usually not needed for brass it's fairly dead anyway.

Yeah guess that might help but you won't have much of a window to get them in before they're back at room temp.

If you put them in the freezer, wouldn't that make them brittle at the cold temperature when you hit them? Or is that not cold enough to do it?

House freezer doesn't get anywhere near cold enough to make them brittle..

Add to that you're reducing the crush fit so less force is needed to get them in and I can't see it ever being an issue.

revive of this post because the picture is gone! I am installing this freeze plug on the front side of the motor and I got the Toyota freeze plug, which direction does it go in the motor? I'd hate to put it in backwards :/

 

[IJ.]

Curved inwards surface faces inside the engine.

 

[oldsking]

I thought so So when I look at it from the front it should look like a bowl and dip in

 

[IJ.]

Nope other way around, curved in surface faces the #1 cylinder or back of the engine.

Domed surface faces front.

(ignore the circle/arrow it was for something else)

 

[hvyman]

No. The front one is backwards.

Take the cup part and push it in the block where all you have left is kinda flat.
