I used to remove them then attempt to force the sludge out with a pressure tester . It didnt always work.,....
Damage? With a screw driver? Damage what? If'n you are tough enough to poke a hole in a cylinder wall or something with a screw driver you's a mean SOB. Kinda sorta the guy who pours Coors on his Wheaties in the morning!Exactly, and pulling the coolant plugs in the block rarely get you anywhere. There is usually a pile of foundry sand and sludge inside that is sometimes tough to get out. And watch out poking screwdrivers and the like in there. You could do some damage.

Did see a guy try to drill out his freeze plugs. That action did lead to a whole in a cylinder wall.
AgreedMy preferred method of removing freeze plugs is, knock them through with a punch till they pivot, then yank them out with a pair of channel lock pliers.
Where the damage normally occurs is the seal surface of the block where it meets the freeze plug. I've seen pry marks that were bad enough where a standard freeze plug wouldn't seal anymore and they had to use one of those rubber expanding types to seal it up.Damage? With a screw driver?

Yes wireslike bits of coat hanger. They are used to position the casting cores. The iron forms around them and they stay when the casting sand is removed. Eventually they corrode at the ends and end up in the bottom of the block.Yep, Core wires. Like "WTF" when you find them for the first time.
Heat around them and melt canning wax into the threads. They should come right out.I like to just knock out an easy to get to freeze plug and clean out the block that way. I've seen many of those block plugs get wrung off trying to get them out.
