Well ive had this coolant leak and i know its a freeze plug. At first i didnt think it would be too hard but now that ive gone out and looked at it, it actually looks pretty tough. It is on the front of the engine. And its a 1997 3.0L OHV, i dont have the tools to take the engine out, and i cant afford to put it in a shop. Any advice would be greatly appreciated...:D

I did one last week on my 3.8 Windstar. It was in the front too, but I was lucky since it wasn't blocked by the exhaust manifold. You might need to remove the exhaust manifold to access the plug, if you don't have enough access to hammer the new one in.

Get a socket that fits on the inside of the new plug (right up to the edges, but it has to fit inside of it) and hammer it in with that, you have to apply the force to the edges as you hammer it in, not the center of the plug. To remove the old one, you need to dent the middle of it and possibly pop a hole through to work it loose. You can also buy rubber ones that you tighten in, that might be easier and even allow you to do it without removing anything.

Hope this helps!

P.S: forgot to mention that you should put some sort of sealer around the edge of the steel plug before hammering it in, I'm not sure about the rubber ones though.

thanks guys both of those were a big help! ill try it out this weekend and let you know how it went.

And something i just learned that might help others reading this if they have the same issue: Freeze plugs have like 3 names probably more. The other two i just learned about are Frost plugs and core plugs. so i guess if you know more names for them post them up cause im sure im not the only one that didnt know... at least i hope not haha

thanks again!

I have replaced them in my vulcan, in fact I had to do it twice. Make sure you don't tap them in the block, if you do this, they are gone for good in the vulcan block, don't ask me how i know.

Second, use permatex #2 around the plugs before you install them. I had to do it a second time because they leaked. (had to fill the reservoir every month or so).

I did them with the removed from the car. You don't need many tools to do this and you can rent a hoist.

I don't think you can do it with the engine in the car, and if one is rusted out, they probably all need replacing, or you will have a similar problem a month from now.

Well also called expansion plugs. And usually the rubber ones are easier to replace but need to make sure they are tight and snug. The metal ones don't need to worry about fit (as long as you have the right and precise size) but getting them in and one are a pain.

Hey guys seeing this I believe I can do it myself I have the same problem except the freeze plug is on the right hand side of the engine if your standing in front of it, is it still just as easy even though it's on the side? I see alot of things Im gonna have to remove.

As Tasslehoff said the make rubber expansion plugs for areas that are hard to get to. I used one once in my work parking lot just to get home. I planned to replace it later. Five years later it still held fine when I sold the truck it was still going strong.
