The engine coolant temperature sensor is located on the driver side of the engine near the rear of the engine compartment

Try this pull the steering wheel as far to the left as possible and while it is in this position try to insert key. Sometimes the steering wheel lock will get in a bind and prevent the key from being inserted. Hope this helps!!!

First do you have a sterring wheel puller. Can't remove the steering wheel without one. Quite an involved job including snaking the electrical connector end through the steering column. I wouldn't recommend it to the novice

SOURCE: HOW DO YOU CAHNGE THE THERMOSTAT ON 2002 CADILLAC DEVILLE

The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.
