Hello. Doing some work on my 47 3100 with the original 216 engine and noticed one of the freeze plugs is leaking. It's just below the water pump and looks to be about 2 inches. Can someone tell me the exact size and where I can get one without having to by a set? Thanks.

You can buy as many or as few as you want at any auto parts store. As for size someone will be along shortly.🛠

Hello guys. Can someone help me out on this please? I took the plug out today. I never saw one like it. It's flat like a 2 inch washer with no hole in it probably 1\8 inch thick. Went to the local Napa but they did not have one and could not get one. Can someone give me a source to order one?

Not sure about now but back when I delivered commercial parts for Advance Auto they had a "bin" with freeze plugs of different sizes and some different shapes. Give them a try......if no luck, look for the oldest longest running parts store in your area. You may have to try one somewhere around Laurens, Easely or even Spartanburg.....like the old Spartan Automotive place which is now a carquest but they use to do machine work/rebuilds.

Wow! we have found the original "Johnny on the spot" Awesome.

I have a favor to ask so that I don't go crazy. I am retired and come from the mechanical design world. Please don't refer to something round as being 2" wide. It is 2" in diameter. smile

Jeez. Get a life. Lol

At least he didn't specify the thickness as xx "guage". LOL

It's just that this could slightly tilt the world and cause global freezing. Plus I'm always on the edge and this puts me over.

I'll try my goodest

2" wide is misleading, I agree with Bartamos.

You know what. I gave him several pictures of the plugs. If he cant figure it out. Not my problem

Johnny, we are joking.
Posted By: Johnny N Re: Freeze plug - Sat Apr 04 2020 12:18 AM
Yup. I know. You're pulling my chain. 👍

My wife works for a school. Been locked up here for 3 weeks with her. You see where this is headed?

Appropriate but probably not allowed here, but funny nonetheless.

Make it the right Diameter.

Hi Johnny. Thanks for the info. Yes it does look like the one on the left. So where can I order one?
Posted By: bartamos Re: Freeze plug - Sat Apr 04 2020 12:59 AM
This [rockauto.com] is $5.50 for 10 or $5.79 for 1.
Unless a cup type would hit something inside the hole or black flow, a cup type would be better/easier to install. you can get a brass 2" diameter cup type which will never rust.
Posted By: Justhorsenround Re: Freeze plug - Sat Apr 04 2020 12:59 AM
Every auto parts store in the world carries freeze plugs. I find it hard to believe you got turned away by NAPA. It’s not even an odd size. You can use either one as long as it is the right circumference but as bartamos said the one on the right is easier for a novice to install.
Posted By: bartamos Re: Freeze plug - Sat Apr 04 2020 01:01 AM
circumference? I'm not taking the bait.
Posted By: Justhorsenround Re: Freeze plug - Sat Apr 04 2020 01:02 AM
I tried🤣
Posted By: bartamos Re: Freeze plug - Sat Apr 04 2020 01:17 AM
Make sure of the diameter. The disc [oreillyauto.com] type are installed with the "dome"/convex facing out. You hammer on it and it expands like a giant welch plug (carbs). The cup type is just pressed/tapped in. if the hole has a ridge/a stop inside, I believe that means you have to use the disc.

I believe I used a #2 permatex sealant on mine years ago. Had a machinist recommend I use it on the expansion plugs,it stays soft and doesn't harden up .

My wife ran out of things to clean yesterday. Today I believe she cleaned the soap in the soap dish in the Man bathroom, which is 49 square feet (Thought I'd send bartamos over the cliff with another dimensional measurement.)
(Sorry mod, I could not stop myself. Theses are indeed trying times.)
Posted By: bartamos Re: Freeze plug - Sat Apr 04 2020 06:56 AM
How many meters is it out to the "man bathroom"?
Posted By: Wally / Montana Re: Freeze plug - Sat Apr 04 2020 05:14 PM
And then there's the freeze plug 600 W heater that has an expandable O-ring for a snug fit. (Or should that be "which has an expandable......"?)

I doubt you'd need a heater in SC like we might in MT but it does plug up the hole nicely.
Posted By: 47chevySC Re: Freeze plug - Sun Apr 05 2020 12:33 AM
Just got 10 of them ordered. Never had seen one like that before. Could not find one on ebay that looked like that for the 216. Spent the day cleaning the motor trying to get it ready for paint. Thanks again for your help and sure I will have more questions the further I go.

47chevySC...it's a given you will have more questions and this is the place to get them answered. Just remember, everyone has an opinion...make it safe and build it like you want.
