This is in relation to an earlier thread I started a few months ago.

With the engine out, it shows that the water seal plug shown here. IT gushed water like crazy.

I will have all the plugs replaced since the engine is out.

Although this is better than a hole in the block, it is a shame that the previous owners probably didnt taqke care of the cooling system.

I have pics, but they are too big and I dont know how to make them smaller.

Well this was best I could do.

Is this a "freeze plug"?

what general area are we looking at?

The area is at the left side at the firewall on the block. Matter of fact the manifold pipes are about 1 1/2 inches to the right of this area.

I had to crop the hell out of the photo to get the size down and I only took one shot of the area.

Engines back in car and car and my self are very happy again.

I would be happy to email the entire pic to anyone interested in seeing it.

Or tell me how to get the whole picture down in file size.

ahh, they're on the head. I didnt know they were there, but yeah, I guess it could be a coolant drain plug..

The proper name is Welch plug. This gives access to the inside of the head after it is cast.

I was going to say core plug or casting plug, but I'll defer to Koz. I think whatever you call it, it is to clean out the casting after it comes out of the mold. Correct Koz?

They are normally called freeze plugs but that isn't the correct term or function. Been called the wrong thing for 50-60-70 years?

I've seen a lot of these things rusted out on cars with poor cooling system maintenance. Brass lasts forever but can loosen and fall out. Steel stays in but rusts.
