Saturn L-Series

This is your Traction Control which prevents wheel spin. Turn it on and leave it on. The traction control comes on with each key cycle The button is to turn the traction control OFF If you want wheel spin or need to run vehicle on a dynomometer or hoist

Not certain on the instrument cluster, could be a fuse. But as for the shifter, I'm pretty sure it IS a fuse. Same thing happened to a friend of mine with the "won't come out of park" issue, when he replaced his battery. After everything we tried it finally came down to the relays and fuse box, where yes, there is a fuse for the elctronically shifted transmission. Hope this helps.

It's intended to prevent excessive leaning when you go around corners. When one front wheel starts to get the extra weight of going around the corner, the sway bar/stabilizer transfers some of the weight to the opposite side spring.

There is no dipstick. Level is checked via a specific bolt hole after engine is warm

and running and the car is 'level'. If the transmission fluid is slightly dripping

out of this bolt hole, or is even with the threads, then the level is correct.

If it is leaking. Fluid will be coming from the right side. Remove wheel and plastic cover behind it. look up and forward to see pully. There is a hole in the bottom of the pump. If you see leaking or streak from leaking . replace the pump.

open the hood, look for it, it will likely have a yellow tipped handle with a finger loop in it, it will be on the outside of the engine, front side most likely. If you are looking for a transmission dip stick, you won't find one, because it does not exist.

Insert the key as normal, but do not turn key all the way. Stop at "acc" accessory, wait no less than 10 min. (I waited 12 once). From "acc" you should be able to start the vehicle. This is called a Passkey re-learn procedure. Basically resetting the computer to recognize your encoded key. Dealerships can hit you hard if they convince you that a scanner is needed!

Idle is computer controlled by the pcm (computer)-not adjustable.

Four quarts

Try putting the key in the on position but dont start it wait 15 to 20 min it should start flashing security right hand corner of the dash take the key out count to ten than turn car on this is how to disable it so maybe it work turn it back on.

Look in the removable housing at the engine end of the upper radiator hose

Possible??? Sure. If properly maintained and if repairs are made when problems show up, it's certainly possible. But it wouldn't happen very often.

Every place I've looked has false info for what color wires are in the door itself! It's said that there are yellow and brown wires, not true..... the rear right positive is dark blue, and the rear left positive is light blue.

That depends on the condition of the engine. Generally, use the lightest grade oil that will keep the oil pressure up. Follow the manufacturers recommendations but if the oil pressure falls too much when the engine is hot, change to a higher viscosity oil. I use 5W15 in ours.

Look underneath engine compartment to rear?

leaking heater core. need to replace it asap, and in the mean time keep an eye on your coolant level

i would assume you need to turn your headlights off as they are the most common reason for the beeping after you turn off the car. My headlights are off and the car is still beeping

Check your battery

A coilpack on a 2002 Saturn L200 can be replaced in shop or by the owner. If the owner is making the replacement the owner's manual or a Chilton can be used to assist in the replacing of the coilpack.

You can not check the transmission fluid on the 2002 L200 or L300, due to this transmission is a sealed transmission. I bought my L200 new and this is one of the new transmissions Saturn was using from Germany. My question at this point is when does the transmission fluid need to be change. Mine has 100k miles plus. I have a chiltons manual on this particular model and this manual gives very ggod directions on how to change the fluid, filter etc. But when. Is 100k miles time to change the fluid and filter. Now I know where to get this answer, call our local Saturn dealer and ask the question.

Take the swith and door panel off - get to the motor of the window, find the live wire and "Hotwire" it using a live wire running from the plus terminal of the car battery. Do with care and patience.

This is not an easy or cheap job... It requires removal of the cylinder head, this basically means taking off the top half of the engine!

you will need to drain oil and coolant, undo all sensors to cylinder head, disconnect exhaust from head, remove timing belt etc.

once you get the head off you need a valve spring compressor to squash each spring and remove the collect's that hold each valve in place.

You need to lap in each new valve before carefully rebuilding the head with new valve seals.

Then you need to put the whole engine back together again with new gaskets and sealants and new head bolts.

I would also advise a new coolant thermostat, timing belt and timing belt tensioner. Possibly also a new water pump. As if these go faulty it could mean you bend your new valves.

new oil & oil filter, and new coolant.

Not a job for a novice or for the faint hearted!

You might want to pack a parachute. Saturn is a Gaseous planet, without a solid surface. You will sink through to the center of the planet, which may or may not be solid.
