Freeze plugs...please clarify
#11
[quote=J415;2072267]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.
So, everyone is in agreeance that I need one 1 5/8 and one 1 1/4 freeze plug, since I have the 5.9? Dealer**** didnt know what the hell I was talking about...hell, they even brought up a pic and asked if the rear main seal was what I needed...
Thanks

Some auto parts stores call them freeze plugs and other call them expansion plugs. I would get 2-1 5/8 plugs and 2-1 1/4 plugs just in case you mess up. I messed up when I did mine. It didn't go in straight. So I took it out and put a new one in. I didn't wanna take any chances.

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.

there are no guarantees. the only guarantee is that it might work and it might save you a lot of trouble. if it doesn't work, then the corrosion will continue and it will continue to get worse. while it could advance from a minor leak to a major leak, its likely to occur gradually. it will never pop out. its a band-aid that might buy you a year or two or five. hopefully to some day in the future when you remove the engine or transmission for a major repair.

I've used stop-leak on domestic engines for years and never had any adverse effects.
However, some years ago, I had a Porsche with an oil cooler (oil is channeled in the middle of a mini radiator mounted to the block) that I used stop-leak on. When I rebuilt the engine, I noticed that 50% of the coolant passages in the oil cooler were completely clogged with stop-leak.
Moral of the lesson...if you have large coolant passages, stop-leak should not be a problem. Smaller coolant passage is a no-no!
BTW...if you use stop-leak it will tend to gather at the lower points of the circulation system which on the 5.9 is around the rear driver side freeze plug. I know this because when I replaced my freeze plugs on my 5.9, the area around the driver side plug was completed caked in stop-leak!!!!
2nd BTW...if you have to replace your rear block freeze plugs, you will have to remove the tranny, not just slide it back a few inches. It would be a good time to rebuild it while you have it out. And go ahead and replace the drive-shaft u-joint(s).
