mistapickles Posted July 15, 2013 Report Share Posted July 15, 2013 recently blew a freeze plug on my car and because I'm not interested in pulling my head to fit a new one I'm looking at one of these. The guy at AutoZone was about as helpful as pancake bunny. How long are these meant to last? What are your experiences with these? http://i383.photobucket.com/albums/oo278/mistapickles/B74ED391-FBAC-4DCD-98EA-FBD4D19A7DA5-9543-00000BDAB54E27CD_zps224fb10b.jpg Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted July 15, 2013 Report Share Posted July 15, 2013 (edited) I have one of those plugging the hole where the distributor went. It seals great and hasn't leaked. I'm not sure how long they are supposed to last. Edited July 15, 2013 by CaliConquestAlex Link to comment Share on other sites More sharing options...
Caliber308 Posted July 15, 2013 Report Share Posted July 15, 2013 They won't last. You would be better off installing Brass Freeze plugs in the intire Engine. Also, if one Freeze plug is bad.....It won't be long before the rest of them are also. Bill Link to comment Share on other sites More sharing options...
G54Bstore Posted July 15, 2013 Report Share Posted July 15, 2013 I've ran those on a mini van for like 3 years before i sold it ..that's the best i can do. Link to comment Share on other sites More sharing options...
jszucs Posted July 15, 2013 Report Share Posted July 15, 2013 Why not just tap a new freeze plug in? If you can get an expansion plug in without removing the head... I'm failing to see why you can't get a proper freeze plug in? You would want to be cautious what it's made out of won't cause corosion problems in the water jacket. I would also be fearful the rubber would not handle the heat well. Link to comment Share on other sites More sharing options...
Caliber308 Posted July 15, 2013 Report Share Posted July 15, 2013 You would want to be cautious what it's made out of won't cause corosion problems in the water jacket. Brass doesn't corrode. Bill Link to comment Share on other sites More sharing options...
jszucs Posted July 15, 2013 Report Share Posted July 15, 2013 Brass doesn't corrode. Bill So do you know the metal of the expansion plug he wants to use is brass? The two laying on my parts shelved looks like some galvanized steal. Link to comment Share on other sites More sharing options...
Shelby Posted July 15, 2013 Report Share Posted July 15, 2013 them rubber plugs are made as a get me home kind of repair,, trusting them to not blow out is not a good idea,, but it's your choice,, spend a little time now or $2000 later when it pops out Link to comment Share on other sites More sharing options...
jszucs Posted July 15, 2013 Report Share Posted July 15, 2013 And just think about what they are "needed" for. It's needed if there is ever a freeze. That rubber is going to shrink allot and be brital in that type of condition making it slipping out easier. + can the rubber handle hot cold hot cold of the motor Link to comment Share on other sites More sharing options...
Caliber308 Posted July 15, 2013 Report Share Posted July 15, 2013 So do you know the metal of the expansion plug he wants to use is brass? The two laying on my parts shelved looks like some galvanized steal. I suggested that the poster install a Brass Freeze Plug, Not a Rubber Expansion plug. Yes,I know what the inside and outside of a Expansion Rubber Freeze Plug is made of: A Steel washer on the water side and a galvanized washer topped with a threaded stud and nut on the outside with a rubber plug in between. I personally would use and have used a Rubber Expansion Plug in a emergency situation (Race boat). Long term??? NO. Brass Freeze Plugs are the recommended way to go.

I would also be fearful the rubber would not handle the heat well.it's under the exhaust manifold and from what I'm looking at it's not a tap in situation. I got the brass plug and it was tighter than a virgin on prom night... not even to mention I didn't have a clear line of site to put it in. Is 50 mm the correct size??? Anywho, I just need something to last a month or so, just started a new job and need it to get back and forth to work for a minute, my girlfriend has my other car.

jszucs Posted July 15, 2013 Report Share Posted July 15, 2013 (edited) So remove the manifold at worst case, It's 8 nuts dude. O and what another 3 for the down pipe or precat Edited July 15, 2013 by jszucs Link to comment Share on other sites More sharing options...
Caliber308 Posted July 15, 2013 Report Share Posted July 15, 2013 Anywho, I just need something to last a month or so. You should be good for that period of time. Just check it daily for leakage. Bill Link to comment Share on other sites More sharing options...

jszucs Posted July 15, 2013 Report Share Posted July 15, 2013 No here is the voice of reason..... Why did you blow one? By where you live I'm guessing you didn't freeze it out? So the voice of reason says better check all of them, and make sure there is no headgasket issue causing ungodly presure in the coolent system.

Shelby Posted July 17, 2013 Report Share Posted July 17, 2013 a rusted out freeze plug is a good indicator of a lot of rust and trash build up in the blockand most of the time you will see no out word signs they are bad , cause they rust from the inside out Link to comment Share on other sites More sharing options...
