freeze plug re-install question

[Chris H.]

Whoa, that's a tight fit. The new steel plug does not seem to want to go back in using a hammer. Are there any special tools that would make it easier? Would a brass one go in easier? Should I file the surface on the block to clean it up a little? What about the rubber expandable ones I've heard about? Any input is greatly appreciated as I'm off the road until I figure this one out.

I would not recommend taking a file to the freeze plug block hole, but I would recommend making sure that it is thoroughly clean. To do this, use Scotch-Brite or steel wool. You want to remove any corrosion or scale deposits, NOT metal.

These plugs take a good wallop to install as they're thick metal and are designed to "swage" themselves in for a good seal and tight fit. One of the problems with installing them when the engine is in the car is getting enough of a swing on a hammer to apply the "persuasion" necessary. You might try a larger hammer, though. It will help make up for lack of swing room.

I don't think that a brass plug would install much easier, but brass is "self-lubricating", so that might help. I'd use brass, anyway. The expandable type plugs will work, but they're, of course, totally non-original.

Hammers

I NEVER would have suspected that you would have a "Bigger Hammer" in your possession.

and den whack the P--s out it. It will go in. Just don't miss and whack your finger.

Tidbit...

Here is a tidbit I learned at a summer job doing refinery maintenance rebuilding pumps and installing bearings - put the freeze plug in your freezer overnight, get everything ready on the block, and when you are set, grab the frozen, contracted plug, run out to the car, and do it to it. The few thousandths contraction really helps out! George, you started this naming thing...

Well, I'm loathe to use it, but, I must admit, that I do keep one around for "emergencies". It still looks like new, though, so I have resorted to using it very sparingly.

Re: Tidbit...

Big Bowtie, I had that exact thought about freezing the freeze plug last night as a lay in bed at 3am.

[Big Block George]

Yeah, ain't it fun?

All we gotta do is find someone named Vinnie and tag him with GUIDO.

Use a socket, extension & lead hammer

We senior mechanics put a short or long (depending on ease of use) extension backward into a socket, and drive that with a lead hammer (to save the extension and make driving easier). The extension saves fingers. I like the brass plug and frozen freeze plug ideas too. - Dave
