If the thermostat has not been replaced i would do this, also while doing this flushed the radiator system out, is also best to back flush they system, also when was the last time the water pump was changed, as over time the fins on the water pump will deteriorate and cause overheating problems, with a/c it will help keep the engine cooler, but you need to check that the parts ive said have been done as this is the main cause of the engine over heating, you will probably find the thermostat is not working properly and there is rust red water in the system, and rusty parts in the emptied water thats why you will need to back flush the engine youtube back flush engine, top up with new antifreeze recommended for your area and engine. and bleed out the air from system. if the water pump has not been replaced in 5-10 years it needs changing.

SOURCE: 2001 Saturn SL2 cam shaft postion sensor

There are no cam shaft position sensors in this model. Check your spark plugs and the wires (boots, etc.) I had the same problem. Also a common problem in this model: if it over heats check your coolant temperature sensor. Jack up one side (drivers) of the car so less leaks out when you check it. The ones that come in the car usually crack, use the copper ones.

SOURCE: 1999 saturn sl2 transmission wont shift from 1st gear

Your valve body and possibly input shaft nut need to be replaced. The valve body's booster valve is worn down and won't create pressure. Before it went completely out it slammed on the input shaft nut and loosened it.

You need to replace the valve body and retorque the input shaft nut. The transmission is not junk. The above needs to be replaced and change the filter and fluid and do it every 20K miles.

Car Won't start after motor swap


Have you checked whether it is on model?,does your vehicle can communicate with the variable sensors of the new engine? are the crank and cam shaft sensors the same on serial number or are different? Does the injection system gets the correct fuel pressure or is not sufficient.

If replaced everything you have to reset your ecm" computer" This will clear out the codes that was showing. If there is still a problem it will comeback up. To do this corectly might run by a dealer, Shoulnt cost just a few bucks. Good luck to you.

My saturn sl2 alarm starts to beep when I try to start the car and won't stop for about a minute. Car won't start. My power locks have been disabled(over a year now). It started acting strangely and...


This sounds somewhat similar to a problem I had with my 1999 Saturn SL2. There was "burning and arching" on the fusebox and it was replaced. The first few times my car would make an extra beep noise when locked or unlocked and I believe the radio/clock had to be reset. The problem got worse although sporadic. Eventually the car wouldn't start - not even making a clicking noise and a big variety of electrical components would not work or didn't sound right.

My 1999 Saturn SL2 started theother day but a few


This is probably a faulty fuel pressure regulator. You can rent a tool at most auto part stores that connects to the fuel rail to show you the pressure level. If it is low (less than @40 PSI) or if it fluctuates very much, replace the regulator. It is also a good idea to replace the fuel filter, as it can clog and prevent adequate fuel supply from reaching the engine. You may want to replace the filter first, as it is usually cheaper.
