Freeze Plugs???

Hello,

I have a 1990 Grand Am with a 2.5 liter engine... All I want to know is how hard is it to replace a freeze plug. The one that went is right in front of the engine and looks pretty easy to get to. Do you just pull the one out and pop in another??? I just need a how to...

Thank-You, Dave

Pretty easy job on the ones that are accessible which it sounds like you have. Just need to get old one out by smacking a punch or screwdriver into the center and pop it out. Ideally you would replace it with a like item, but much easier is the expansion type repair plug. It's rubber with two big washers and a nut sticking out. Stick it in the hole, tighten the nut, the washers compress the rubber donut, and it expands tightly against the hole. All done.

I admit I've used the ones with the nut and washers but does that void it as being a freeze plug? Will it still pop out in a freeze situation?

I believe so .

Besides, it should never get to that point where it needs to "work"

I.e, your cooling system should be maintained.

"Freeze plug" is a bit of a misnomer. All they really do is fill in the holes left over from casting the block.

Hey, Joe, what is the "official" nomenclature for freeze plugs?

I believe it's "Expansion plug".

I emailed the manufacture of those ruuber expansion plugs a few months back and they advise to check and retighten them as time goes by.

Allen1 is correct! They do loosen up, and that is why I don't like using them, I learned the hard way.

If you can install the rubber you can tap in the metal plug as well.

Just my .02 worth.
