My wife's grand prix started leaking antifreeze the other day. I took it to a repair shop and they said that the leak was coming from a frost plug on the timing chain cover. Have you heard of this and is there a replacement? They said the GM dealer in town doesn't list the plug itself as a part that you must replace the whole cover which is a big job, I guess. If you take the alternator off you can see the plug so I though I could replace it myself.
