Work is never done. I was looking at the bottom of the car and saw a couple drops of coolant. My first thought was the water pump. I recently replaced all the belts and installed a S5 alternator. I thought I might have tightened the belts too tight and cause the waterpump to fail. Well, it was not the water pump. There is a very small leak from the plastic plug on the botton of the radiator. So I tried to tighten it with a wrench. I sanpped the head of the plug off. I was not even turning the wrench that hard! Well, I was able to back the rest of the bolt out. The problem is I can not find a replacement bolt anywhere. Is the dealer my last hope?

Help!!!

 

i had the same issue and the only place i could find one was through 1800 radiators and also the dealer has them.

im guessing it's pipe thread.......so go to a plumbing store or big box and get a nylon hex plug. prolly 3/8 or 1/4npt

 

I just replaced my rad this evening so I happen to have an extra one. Send me like a dollar or so for shipping and its yours.

 

Thanks for the information. I think I will go to the junk yard and see if I can score one off an old 7 or other mazda car. If not I will have to go the the dealer to get one.

IanS, thanks for the offer. I need the plug ASAP, so I will still call you if I can not find it anywhere.
