The adjustment screws/nuts should be located either on the top of the headlamp assembly,
behind the headlamp assembly, or near the frame rail by the radiator
You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well
Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)
For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.
For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

your best bet is to go to your choice of auto repair store and purchase a Haynes Repair Manual for GM it covers the Cadi, Olds Toranado and the Buick Rivi 86-92, its located in the back section of the book youll have no problem locating it.

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.

Get car on a lift as the filter is under car close to where your gas pedal foot may rest. Two open end wrenches will take it apart.

First, I would determine it is bad. I have a 1990 Cadillac Sedan Deville, and sometimes it doesn't turn over. But, if I toggle the switch a few times or up to 5 times, it starts to turn over and the car starts.
I have the same problem with a 1997 Cadillac Deville.
If you are set on changing it, here is a picture and instructions on how to test:
Starter TESTING Voltage Drop Test Fig. 1: Schematic of a voltage drop test
NOTE: The battery must be in good condition and fully charged prior to performing this test.
Remember to disconnect the battery and remove the wires from the starter at the hex nut.
Then, remove the 3 or so bolts that hold the starter on using an extension and ratchet if necessary.
Hope this helps.
