Projects 1950 Plymouth flat head 6 freeze plug

Looking for guidance on installing the drivers-side, top of motor, rear freeze plug. I have new ones but never did this before. Any help would be appreciated.

Thanks!

 

First be sure the opening is clean, free of rust where the core plug sits. I use a sealer, Permatex #2 works, just a little in the hole. Insert the plug, convex side out. Seat is firmly and square in the hole. Now comes the hard part because there is often something in the way of a good hammer swing, hit the plug in the middle firmly to cause the center of the convex to invert to concave. Not the whole plug 1/2 or so.

I use a ball peen hammer when it fits the space. Otherwise, improvise. A large punch with the end ground to an arc can help get around stuff.

 

Thanks KenC!

 

After you have knocked the old plug into the block, a brake spoon works good to pry it out. Tap the new one in and you are done.

 

I drill or punch a hole on the old one, then pry it out with a screwdriver in the drilled hole.

 

Thx goldmountain and BJR. I had the motor rebuilt about 4-5 years ago and for whatever reason, [they] didn't reinstall this particular freeze plug. So, no need to remove old, just install new one.

 

Here in the land where it is always winter but never Christmas, we would fill that hole with a block heater.

 

Do these engines use a deeper "cup plug" or the shallower style "welch plug"? The R&R could be a little different. Is the engine in or out of the vehicle?

 

ClayMart, I purchased a set of replacement freeze plugs from Andy Bernbaum. I only needed the one however, they came as a set of concave plugs. Then as noted above from KenC, I installed it with the convex side up...all went well.
