Hey all,

Can someone please tell me what size of freeze plugs I need for the rear of the block (between tranny).

Thanks

 

Not sure, but you could just get a kit and use the ones that fit.

You need a shallow 1 5/8 inch BRASS plug. They cost about $4 a piece.

 

1 is 1 5/8 and the other is 1 1/4.. are you sure its the rear ones leaking and not the one by the oil filter?

 

I did mine last year and they are 2 different sizes. I can't remember the size, but I removed mine, then mic'ed it and found a match at Advance. It needs to be a tight fit!

 

Im pretty sure its the rear ones. Im putting it up on a lift on Friday to check it out more and fix whatever it is. Its dripping off of the bell housing. Also going to check the rear of my intake manifold, since I just did my plenum and noticed it after that. I smelled antifreze before the plenum tho, so thats why I assume its a freeze plug.

Either way, I will definately check it out real well before I pull the tranny for it to turn out to be an accessible one.

 

I hate to disagree, but I just did mine last week and they're 1 5/8. He's talking about the ones between the tranny and engine. Those are BOTH 1 5/8. He's not talking about the one's behind the heads. I know those are smaller.

 

Perhaps we have different engines. My block freeze plugs were definitely different sizes. See pics

Yeah, we do. I have a 5.2 block. So I guess we just figured out that the 5.2 block takes two 1 5/8 plugs and the 5.9 block takes one 1 5/8 plug and one 1 1/4 plug. Sounds good. This should be in the FAQ page.

On a a side note, thanks for your tranny rebuild notes gobbell1. I'm in the process of rebuilding my tranny and your pics and note are very helpful. I just hope that my completed tranny comes with the same success you had with yours.

 

J415...you are most welcome on the pics/manual. I noticed that some of the pics aren't as clear as they need to be. So, if you have any questions, please let me know.

15k miles on rebuild and counting!!!!
