are you talking about in the engine block?
because that is your water temp sensor sending unit..

it is a coolant sensor, just be carefull when taking it out, i broke two of these and had to replace them when doing my lt's. use a deep-well socket and don't let it slip off, it will snap the plastic end right off and cost you around 25 bucks for each time you screw up!

I broke that one and the one on the water pump... that damn plastic gets brittle, be careful.
