High temp reading

Just incurred a above and beyond high temp reading on the interior temp gauge on 04' Impala 3.4. Fluid levels are fine and engine feels fine to touch. I did change plugs and wires last week (without tilting motor, that was fun). Just had oil changed yesterday (cheaper than d.i.y). Wife said the gauge tagged almost parallel past temp red area, I did verify. After reading some posts could I have knocked loose a sensor wire. I've been trying to locate some diagrams or pictures as to the where-a-bouts of these temp sensors. I could use some help. Is there a free repair manual or engine parts location diagram out there? I was lucky once and someone had loaded a repair manual on a forum for PT Cruisers for all to have...that was nice. thanks for any help.

By the way, think it's okay to drive and not worry until this little mystery is solved? At what temp would the engine temp light come on and be able to shut her down?

Have you worked with the engine coolant system at all lately? If the temp rockets up and the coolant seems to be ok, maybe you've gotten air into the coolant system.

Have you ever changed the thermostat?

I don't think the car shuts down at any temperature unless mechanical failure physically prevents it from running.
