Hi, so I just changed out the rear freeze plugs in my 97 f150 v6. I have not put it back together yet because when I put the coolant in it still dribbling out very little but I didn't know if the engine had to get up to temperature for them to set in all the way. I figured I would ask on hear so that I don't have to drop the transmission again. Please let me know thank you.

 

Not knowing exactly what you did , suppose we just go over the steps in case you missed anything..
First you need to have the correct plugs
Then after removing the old plug the surface needs to be perfectly clean to accept the replacement plug.
Once you set the plug into the hole, you use a ball peen hammer, have the round end against the center of the new plug and proceed to tap the flat end of the ball peen hammer until the plug is almost flat.
By this time it should have expanded sufficiently to seal the opening.. Some folks will put a coating of RTV around the shelf before inserting the new plug.
Never had one leak yet !

 

Ok I did clean the holes one of them though had a lot of rust in it and it it corroded a bit. I got the freeze plugs that the atou parts place said it needed. And the video I seen online said to use a socket and hammer to put in the new plug. They do make a rubber plug would that be better because of the corrosion from the rust.

 

Just how bad is the surface where the plug seats and the circumference
If you can get hold of some "Permatex avation form a gasket" place a good coating of that around the block then insert the plug., that stuff will stand up to oil, coolant and just about all liquids except methyl ethyl ketone..MEK.

 

Ok I'm going to let it set over night and check it. I do have so of the gasket stuff. And that one is quite bad then I got it all apart the plug was just sitting there and fell when I got the Shield of the engine. I should mention that I just got this truck 2 days ago. And it has probably been sitting like that for about a year I was told. The truck is in really good shape. Besides that. No rust good frame. Just about every thing on the truck is new or has been replaced in the 10 years. One of the cleanest trucks I have seen. Really for it being a 22 year old truck you would never know it.

 

Pull the plug out. It should not leak,ever. I would install another new one. Dry thoroughly and clean the surfaces with some emory cloth and apply a even layer of Permatex # 2 (not RTV) on the sealing surfaces on the engine and new plug and drive it in evenly.

Permatex is what I used to use back in the day.

 

I don't have the time to get to it today but I'm going to pull them both back out tomorrow. I did clean them really good. Made sure that it was dry. Ilke I said it the post above. The one was corroded from the rust pitted quite a bit. I'm going to use the permatex. On it then up date you all.

 

Read the Permatex tube for directions. If I remember correctly there is a "set" time for the Permatex to cure. Hope this helps.

 

Be aware,
Permatex No1 is the hardening type
Permatex No2 is the non hardening type.
Permatex "Form A Gasket" Was used on older type head gaskets and cooling system components like water pumps , hoses etc.
