Hope helps.

I worked on a 1999 Deville and to remove the oil pan wasn't to bad to change. All I had to do was Jack up the car and support it.Also remove the negative battery terminal.Drain the oil then remove the torque converter cover bolts and then the oil pan bolts and remove the oil pan.On some model Cadillacs there is also an exhaust cross under pipe that also has to be removed.Be sure not to over tighten the oil pan bolts there real hard to get out if you break one.Your going to have to find out how tight they should be because they all very depending on the vehicle.Most all of your auto parts stores have this information.

Removal of pulley is usually the main problem... a special tool is used for this. and another special tool is used to replace it. Once removed the valve cover will rotate slightly toward windshield and slide toward drivers side of engine. A power stearing tool can be used to remove the pulley and a bolt with a stack of washers can be used to install the pulley. Good luck.

put it up on jackstands ,be very carefull .take transmission pan bolts loose and drain fluid into a bucket or pan.once the fluid is drained remove bolts from pan change filter and gasket.

on driver side under the hood at front remove the bottom radiator hose from the engine remove two bolts and the thermostat is behind that make sure you install it correctly

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

Follow the upper radiator hose to the point where it enters the motor. Disconnect it at that housing and remove the bolts holding the housing in pace. Remove the housing and all of the old gasket. The thermostat sits under that housing and just pops right out. Install the new one along with a new gasket. Put everything back in the reverse order.

4.6 Northstar V8. It is located on the rear of engine (driver side) in front. It is 1n the the waterpump housing cover. Remove airbox and intake tube and bottom radiator hose. 2 bolts(believe 10mm) on thermo housing. These systems are a lil finiky about air pockets....so fill slowly and let run at idle until operating temp and let cool and chk level.....fill as needed and repeat if needed.

easy as, 2 bolts at the front and 3 wires at the back remove all and it should come free, the motor is at the front of the tranny it is attached to the flywheel, disconnect battery first
