Cadillac STS

I have been having the same problem and the first time I also replaced the starter (battery was already OK). Seemed fine for a while then it happened again. And by the way, when I first replaced the starter, the old one checked out fine but since I had the car all torn apart, I replaced the old starter anyway. Happened again, and took the starter out and it checked out fine. Reinstalled, started 2 times right away. Then later, wouldn't start but just did the one click thing like you've described. Several hours later, started right up and has continued to start right up even though I am not driving the car because now I don't trust it. But I am now in pursuit of the neutral/safety switch which I have come to find out causes the same exact symptom as a bad starter. Haven't gotten it out yet but I understand its position is ADJUSTABLE and I think that's where the problem. I have gotten the first bolt out for the switch and I noticed it wasn't TIGHT. That slight shifting from the action of the shift cable is probably the culprit.

4.6 Northstar.It is located on the rear of engine(driver side) in front. It is 1n the the water pump 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.

Check the battery connection, under the rear seat.

no, it is a self contained system ...Have a caddy tech check it from underneath

your car has a passlock antitheft system. there is a resistance value in your key that sends a signal to you cars computer to start the car. i dont believe there is a fuse

Check the upper and lower radiator hoses at the engine. They have a tendency to expand and split.

It's a straight order 1,2,3,4,5,6,7,8

Northstar engine is rated at either 280 for the SLS or 300 for the STS for 1999.

There is a plate under the car on passenger side. Remove this plate and you will be able to see the alternator. I think it has three bolts.

Not sure about a 1999, but there are 2 fuse boxes on a 1997, one under the hood and one in the trunk. Hope this helps.

The water pump housing is the bottom radeator hose on the right side of the engine. You will need the GM water pump remover tool, you can rent one from Auto Zone or a similar store. remove the hose and the outer-caseing, the waterpump is now slightly visable. Use a .5 inch rachet with the GM tool and turn clockwise.

Just below the tank

Yes same motor dimensions..............keep your sensors from old motor!

Sounds like you need a tune up........Or you have water in your gas Sounds like you need a tune up........Or you have water in your gas Sounds like you need a tune up........Or you have water in your gas

when you open up the hood of your car look to the right side of the engine block, and there should be a black rubber tube with a plastic shroud covering it located right in front of the coolant tank. this is the air filter housing and will need to be removed by unclipping the 2 clips and one ring that hold it in place. also make sure to disconnect the sensor located on the rubber tube. after that has been removed under where it used to be should be a dipstick for the transmission fluid. and on a side note if your transmission fluid is dark yellow to brown, get it changed immediately!

Cadillac recommends you use Premium fuel of 91 octane.

Your thermostat is probably not opening.

I know the oil filter is a Fram CH8765, its very small because it can be changed easier than other filters. If you look under your hood and find the oil cap it says Mobile 1 on it, to the right somewhere, not under the black engine cover, there is a silver cylinder with a lug nut shape on top. You have to use a wrench to get it off, but its inside there. To drain it, about directly underneath the car in the same spot another nut or bolt to unscrew with a monkey wrench. Sorry I am a girl so I dont know all the right terms, but my dad is smart and he showed me. Lol!
