Question about 2000 Saturn SW2

1 Answer

I have a 2000 Saturn SW2 DOHC. I've noticed that when the car gets a full tank, then hits 3/4, the service engine soon light comes on. It'll stay on for a couple of days, then go out. It is on steady and not flashing. The car runs normally.

I tried to get a sticker and failed because it stated that 2 (02)sensors, catalyst and evap were not ready on my 2001 saturn sw2. How do I fix this? I have been over 300 miles and have failed twice.w

It is not something you fix, the system self tests after any time the battery is disconnected or the system reset with a scanner tool. Drive it until it clears, take about 20 miles of mixed driving, idle time, freeway, moderate speeds like in town. Gas tank must be at least 3/4 full for the test to complete. This is known as an OBD2 drive cycle. If you had a check engine light and it comes on again then you did not fix the problem.

My 2000 Saturn SW2 is making a squealing/whistling sound when I drive, it generally stops when I apply the brake. I've been told it's an indication I need brakes.

well then you should have someone taking a look at the brkes. the brake pads have a small metal tang on them which begins to drag on the rotor when the pad thickness gets too thin. this is to let you know to ge them checked. it is 11 years old and brakes wear out.

if that is not it, have someone check the belt tensioner, those tend to cause squealing belt syndrome when they get old and lose their tensioning ability.

My95 saturn wont move how do i remove my tranny and will a tranny from a 2000 fit

the first thing you need to do is figure out what engine you have. there are only two saturn engine blocks 91-99. one is a DOHC for you a SW2 and the other a SOHC for you a SW1. The transmissions for the two engines are different, common mistake you should not make, different final gear ratios. When you find that out call a junkyard and they have interchange numbers to tell you which year saturn transmissions will fit, probably a 95-98 will go in.

I have a 1997 sw2 1.9l dohc. I just installed a new

Sounds like you may have the solenoid wire end touching the power wire, causing the starter to run constantly. If not, you may have a bad ignition switch.

96 saturn sc transmission problem

Are you sure you are getting the right trans? There are 2 different based on sohc or dohc. The rpo codes are mp6 or mp7. The gear ratios are different and will set these codes.
