Drilling thermo to allow air to escape.Where to drill? (pic) ok, I had this thermo not open for me when I installed it on my car a couple weeks ago. I was going to return it to Thunder Racing but they never returned my call. So... I tested it and it opened at 160* I figured a pocket of air (as others have suggested) was trapped and prevented the water from reaching the thermo. I am not exactly sure where to drill. I can only see two logical places and I have labeled them #1 and #2.

Re: Drilling thermo to allow air to escape.Where to drill? (pic) I have the same T-Stat sitting on my desk. Notice the little brass arrow head looking thing at the 6 O'Clock position (Your arrow at 9).
AFAIK, that little hole does the same thing your trying to do with the drill bit. Very strange that yours didn't open though..

Re: Drilling thermo to allow air to escape.Where to drill? (pic) Yeah, that's what I was thinking. It sure didn't open though.
Hrmmm... now I don't know what to think. I wish Thunder would call me back so I could return it.

Re: Drilling thermo to allow air to escape.Where to drill? (pic) Wouldnt it be two>? Thats where the water would stop right? Then if the hole was there water and air could pass, thats if my thinking is right...
