New here from the S.F bay area. Havin a issue with my 2003 monte. I have a 3.4l and its leaking coolant. I isolated the leak to the freeze plug on the back of the rear head. I have already removed everything, just not to sure how to get the plug out/in. Is there anyone out there who can give me some pointers? thanks in advance

 

hello and welcome. wish i could help. ill try to find my manual 2moro and c if there is anything in there about it

 

i'm not familar with the 3.4 but are you talking about coolant elbow?

 

No, its the freeze plug in back of head. It seems to have a crack in it.Will not hold no pressure. As soon as you start it, it comes flying out as if you drilled a small hole in the plug.
