Michelle,

The 1997 V8 engine in the car is fitted with coil packs which are quite visible on the top of the engine. These need to be replaced when they eventually fail as is common.
Here is a video on the coils which may help you.................

How To Install Replace Ignition Coil 96 99 Cadillac Deville Northstar 4 6L...

For my 1997 Cadillac Deville limousine with 4.6 L Northstar it should be 196 to 205 deg. And top out at no more than 230 deg. F. Check multispeed fans for high speed turning over and antifreeze fluid level in overflow tank. Also, check for head gasket leaks through tailpipe which will show up as steam when you start the engine.

The fans /fans are turned on by the pcm, using input from the coolant temp sensor, as well as the HVAC system. The cts is on the right rear of the engine below the egr valve.

Hope helps.

Assuming you have the Northstar engine

you don't, the water pump has pulley built in. (it's located on the driver's side in the rear of the engine in case you mis-understand that it's on the front of the engine )
there's a special tool to remove and install the water pump.
if you have the tool the the job is very easy

located underneath the intake manifold remove it and disconnect the knock sensor unscrew the knock sensor. installation is reverse

the belt is on back of head,no hard to do.remove cover,release tension, by pulling back on tensioner.
with car off grab belt with your hand and pull,this way you can see how tensioer releases tension.

it is located where the air fillter hose connects to the engine
