Core Plug ("Freeze Plug") Fun 🤬
Hi all! It's been a while - multiple concurrent toys I've been working on.
This is being very very stubborn. Ideas? I removed the starter for good access.

Since you gouged out the bad freeze plug you have to decide if you're going to replace it lying on your back under the car, or if you're going to remove the engine. If you decide to remove the engine you MAW replace all the freeze plugs and do other maintenance that might be needed. What's the condition of your oil pan and timing chain cover gaskets?

I am focused on this one plug for now. I was not expecting it to be this stuck. I've pried quite a bit, even bending a 3/8 ratchet extension in the process.
Any ideas how to get this thing out?

Yeah I had hoped to smack it hard enough to get it to move. The approach is a little bit angled. I also figured prying it would help. It's still firmly in place. Now I'm thinking in terms of chemicals and fire.

If you have a channel lock pliers, you may be able to get the tip in there and wedge it out.
You can get an expandable rubber freeze plug at an auto parts store.
That will be much easier to install lying under the car.
That will make a great temporary repair until the other 5 plugs start leaking.

I had the same issue with my engine on a road trip when i first picked up my car , same frost plug behind starter , frost plug was rusty and dumped the coolant . For a quick fix had a shop install a block heater , that plugged the hole until i could get the car home . Then had a local shop replace all the frost plugs except one , they were not able to do the frost plug behind the dip stick tube , with out breaking the dip stick tube so that plug still needs done .
As Charlie said the others will go next , so one done but more to go .
Question is this issue do to acidic coolant ? or would happen any way ?
2nd question is there another frost plug between the engine and trans that could corrode and leak coolant ?

In some localities the water is acidic, and it is recommended that distilled water and antifreeze mixture should be used.
#2,Yes sometimes there are, as well as plugs in the cylinder heads.
