I have a leak coming from the engine temp sensor. I need to know the procedures for changing this and what tools are needed to this and are there any special tools or steps that need to be taken to this?

Pretty straight-forward operation, usually involving these steps:
. Drain antifreeze to just below sensor level,
. Remove connector and sensor,
. Install sensor with a new O-ring,
. Torque to somewhere around 15 ft.-lbs. and
. Button things up.

Are you shure it is the temp sensor and not the lower intake gaskets cause they are known to leak on 3100 and 3400 motors but if not just a 7/8 wrench and careful not to break the new temp sensor
