Freeze plug problem
I was about to make a 150 mile trip today. When I pulled in for some gas (In town thank God), I noticed that there was a thin stream of water pouring out of my starter. I drove the truck home and dropped the starter and just as I suspected, the freeze plug behind the starter had a pin hole leak in it. What does suprise me is that I just put all new ones in a year ago. I also pressed a screwdriver on the hole to see if it would go through it (to see if it was a rust hole) and it didnt. The way the headers are set up theres not even enough room for me to take the thing out much less hammer a new one in. I know it sounds shoty, but if I find that it is just a small pin hole, whould JB weld suffice? What do yall think I should do? I dont want to have to take the engine out again.

Re: Freeze plug problem
Are the steel plugs? do you run coolant/antifreeze? I would not trust the JB weld. Brass plugs and never deal with it again.

Re: Freeze plug problem
cant you just drop the header for clearance/ passenger sides have alot more room to work than driver side// i'd take it out and do it right

Re: Freeze plug problem
X2 I know it is a pita too change it, but dropping the header and fixing with a brass one is the best advice. While at it I would change them all on that side of the block while the header and starter are off.

Rubber expansion plugs are available for emergency repairs, or if removal is easier than installation. Do not use sealant on rubber plugs. http://www.automedia.com/Article/ima...0401fp_s05.jpg If you go this route be sure and get one at an auto supply store not a hardware store. LockDoc

Re: Freeze plug problem
Although this is of no help, I could not help but share this... My instructor at school will get pretty upset if you call them freeze plugs, instead of core plugs. He made us watch 2 or 3 old videos of engine casting and made it a point he never wanted to hear "freeze plug" again because they are called core plugs in the videos, and that's what they are...
He's very detail oriented Good luck with your freeze plugs

Re: Freeze plug problem
If the hole is small enough have you thought about using Bar's Leak?

Re: Freeze plug problem
I have used the dorman copper expandable core plugs with great success. I would recommend one of these before rubber if your not going to replace with a brass core plug.

Re: Freeze plug problem
I thought the ones on the side were freeze plugs (http://en.wikipedia.org/wiki/Core_plug). I guess I could drop the header and see what I can do. I asked Oreillys if they had the brass plugs and they didnt. Who would carry them?

O'Reilly's has them online and the store should be able to get them in the next freight order. http://shop.oreillyauto.com/ProductD...e=1022&PTSet=A A lot of parts houses stock Dorman products and may have that part number or single Freezr, core, expansion or soft plugs depending on who your auto shop teacher was. By rights and regulations they are "core" plugs though and never were intended to pop out when the water in the block froze. NAPA parts numbers listed here. http://www.napaonline.com/MasterPage...=10&SubCatId=4 Page 9 Last edited by mr48chev; 10-17-2009 at 03:23 AM. |
