Hey guys, I would like to install an after market temp gauge, at least temporarily to have more confidence in my operating temp.  My dash gauge is working so I'd like to leave it in place while I have a second aftermarket gauge so I can look at them both simultaneously.

I'd like to avoid having to pull any freeze plugs etc.  Is there an alternate spot to put a sender?  How about somewhere in the radiator return hose or something novel?
