Engine/Transmission (1998.5 - 2002) help! block freeze plug issue, size p/n how to...

[IC Smoke]

Well im in the process of installing my HTT manifold and PDR hx40, and i came accrost this wonderful lil pest... . (pics) soo how do you change it? or how does it come out and install? any part numbers for this (I think its 2 1/4"? or slightly larger) Will I have to have the truck towed to the dealer? Id like to finish the install but NOBODY has the plugs in stock! plus I need a pyro part as well but thats the least of my problem here.



Thanks guys!!!



*In the pics the rest of the "wet" look is from PB Blaster sprayed on the bolts / overspray but you can tel its comming from the plug in the 1st pic*

ian i think to get the freeze plugs out (if i recall correctly) you can drill a hole in the center of them and use a slide hammer to get them out... i did this on a 1953 dodge powerwagon straight 6 engine in shop class... the only problem is i wansnt there when the teacher put them back in so im not 100% sure on how you get them back in...

don't know if its the correct way, but I always used to use a flat punch and a hammer on the inside corner of the plug, this would turn it sideways in the hole, then a pair of channel locks to pull it out. By using a slide hammer I would think your actualy trying to expand the plug into the hole as you pull on it.

this is how i get them out usually. most plugs i ever do are so rusted that they are too weak for pulling with a slide hammer anyway.

Freeze plug install

I normally coat the outside of the new freeze, welch plug with soft Form a Gasket compound and you can use a large socket and a hammer to tap, drive them in flush with the engine block.

Permatex #2 non hardening is what I have always used.

Form a Gasket

Permatex #2 is an old formula but it works mint, still used in the industry. You can also look for Permatex Aviation form a gasket, basically same stuff but in a can with a brush applicator.

To make sure it gets started square place a large dia. socket in the plug to tap on if you don't have a freeze plug/oil seal driver. Of course don't tap in too far or you'll be starting all over again and need another new plug. You may consider changing them all since you are right there??? May wish to paint after install to keep rust from starting MHO.

I just might replace them all, thats a good idea. If I tap one end in then pull it out will it damage the seal of the next plug? (talked to R-N-R over the weekend and he brough that up)





Thanks again guys!

No. It should not cause any problem with adjacent plugs. I think I would do as suggested and replace all the plugs on that side of the block. Coat the outside of the new plug with permatex #2 and also coat the hole in the block before installing. I would also make sure the block hole was clean with no previous sealant left behind. I generally clean them up with a piece of 80 grit sand paper. Just make sure when your done that the plug looks square in the hole.
