I ran into an old friend yesterday that happens to be a good mechanic. I was telling him about my Mustang and he recommended removing the freeze plugs because old engines that haven't been run for awhile accumalate rust, which can cause hot spots. Anyone done this?

you can remove the CAST plugs because they are usually what will rust out first, i use a good wire wheel on the die grinder to clean the holes, you will find that sediment and rust will accumulate in the pockets, the more you get out the more efficient the cooling will be, dont knock them in because they are a beoch to get out, try to slide hammer them with a pilot hole and screw

When you do replace them,get brass ones as the steel ones don't last long.When I had my heads done,the shop forgot and put steel in,they lasted about 10yrs.

I really don't think I would go this far with the freeze plug removal unless I was re building the engine and having the block boiled. Do you really think it's worth it? That inline has a very simple plumbing layout so I Think some creative engineering with some hoses, and you would be able to back flush the block.

it would be a last ditch thing i would do if i could not absolutely figure out a cooling issue, but to do it just for the heck of it ..no. It is a must though when i boil blocks in my tank, sediment does build up over time in the cavities, at times i will put hydrchloric acid in there then hot tank it, the acid removes everything
