Where can I find the coolant temp sensor (pictures if possibe) ? Also can any one link me a how to replace it?. Thank you.

I have a 96 Civic EX.

 

Standing in front of the car, look on the left side of the head. There is a coolant hose, the coolant temp sender, and then another sender unit. The coolant temp is the one in the middle, the single-"pin" unit that you can just pop off the connector to and unscrew. Warning, the sender might come apart during the unscrewing due to it being brass I believe...or some other britle metal.
