Frost plug heater troubles

[Hulapopper]

New to forum. I'm trying to replace a frost plug heater on a satoh buck. It is a Katz brand. Unable to remove old one from block, any tips or tricks? Missing in pic is plastic cover and wiring.

Could this be moved to the satoh forum, newb mistake.

That almost looks like a press fit but I have never seen a press fit block heater. Do you have a replacement heater to look at for reference on how it installs?

I do not have a replacement yet. Need a measurement. Original is a thicker steel, not brass like most new ones.

That center bolt wouldn't operate the wings on the back side by any chance, similar to a toggle bolt. If it is, a tap on the bolt should knock the wings free. Any frost plug block heater I've ever seen typically uses the same type of clamping arrangement, not saying this one isn't different somehow. Hopefully someone with more experience will chime in.

You could try prying on the bolt or you can take a punch and knock it loose.

It does. Knocked the wing into water jacket.

Cannot get anything in there to pry. I have smacked it with a punch.

Then weld something to it and pry it out.

Hopefully it's not threaded in.

If had wing type toggle bolt it will not drive out since has shoulder on to allow toggle to tighten up. You may have to drill a couple holes in it and pry it out.

I don't know, but could it be heated with a small torch to loosen it enough that a long punch and pry method might work?

Probably gonna have to work at it by driving a flat screwdriver into the fitting so it can be distorted and ripped out.

If you show me a threaded freeze plug hole, I'll buy you a happy meal. How could it freeze and pop out if it's threaded?

I thought 'freeze plug' was a misnomer. I thought it was actually used in the casting process, I stand to be corrected tho.

Git it out with a drill and seal puller.

Some other freeeze plugs in there only 1/2 diameter. I didn't know if this was specifically for a block heater.

For installing a freeze plug we used a socket to tap them in. I have only seen block heaters that have threads to hold them in.

Cold chisel & punch the sides inwards.

Glad the OP got the heater out!

I have seen threaded "freeze" plugs, as well as threaded plugs in the water jackets.
