1999 Leaking coolant from bolt in motor

[pws]

I have a v6 3.4l in my 1999 grand am. I had a coolant link and found it to be linking from around a bold that is by the thermostat. You know where the hose on the top of the motor on the right hand side there is a bold that is there that’s not part of the thermostat but is right near it. The head if the bolt is facing the rear of the motor at a slant. Well that bolt was loose. It was linking around it pretty bad. I tighten the bold and it stopped. Now my car is leaking again from the same spot. What would cause it to link around that bold? Thanks.

Put some RTV sealant around the thread of the bolt before you put that bolt back in and tighten it.
