I have a 2003 Saturn ion and the clutch quit

The clutch master and slave should ALWAYS be replaced as one repair that said the slave is always the first one to fail due to heat, the reason both should be replaced is this, debris from the failed cylinder will ruin the new cylinder, I have learned this over the last 35 years as a dealer technician. The slave is a direct acting unit, that means it sits on the input shaft collar of the transmission and is also the release bearing for the clutch disk. The transmission must be removed to replace the slave cylinder, the parts are about $375.00 for both master and slave. If you have it done since the transmission is removed the clutch pressure plate and disk should also be replaced as well as having the flywheel refaced.

03 saturn ion coolant message

I have a 2005 Ion that had been displaying the "coolant" message for quite some time. The car runs perfectly, never overheats and the coolant bottle is always full to the "cold fill level" line when cold and slightly higher than that when hot due to the expansion of the fluid. (all completely normal) I had a strong feeling that the coolant level sensor in the coolant bottle was bad and had read about how it needed to be replaced by a tech and all but I wonderred if there was a way to defeat the sensor since I check my levels all the time anyway because the sensor was really just giving false info anyway. I couldn't find a tread involving a Saturn that talked about a solution other than having a tech charge me lots of money to replace the whole bottle. I found a way to bypass the sensor for a BMW though and thought I would try it. It worked perfectly. I plan on replacing the bottle eventually but right now money is tight and I don't need the sensor to tell me what my own eyes and my car's temperature gauge can tell me for now. Here's how you do it.

1. Unplug the sensor harness from the bottom of the coolant bottle.

2. Find a large paper clip and use needle nose plyers to make a "staple" shaped jumper that is about 1/4 inch wide (about the distance between the two contacts on the harness) and about 3/8 inch long.

3. push the jumper you just made into the end of the harness connector.

4. Start your car and ensure that the warning is no longer displaying. You can also insert the jumper while the car is running (be careful, the coolant bottle will be hot) because the harness is removed from the sensor the coolant warning should already be displayed. When you insert the jumper the message should go away imediately. The coolant level sensor has only one job and that is to tell the computer when coolant is low so you don't have to worry that you may be causing any other problems by doing this. If the coolant light doesn't go away you may have a break in the wire somwhere or a bad connection to the jumper.

5. If all works well, use electrical tape to seal up the end of the harness so moisture doesn't get in. Also it's a good idea to secure the harness to something nearby so that it doesn't flop around when you are driving.

All done. Sorry this was long but I hope that it helps someone. That warning really has been irritating me.

Keep in mind that this method does disable a key safety device that is designed (poorly) to warn you in the even of a coolant leak. Keep an eye on your temperature gauge and check your coolant level regularly. Get the bottle replaced when you can.

Pwr str servcie vehicle message came on... Steers

PWR STR message Power Steering: Refer to Power Steering System Description and Operation in Power Steering System The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly. Having a qualified repair shop check it out would be your best bet ! Do you know what DTC'S are ? diagnostic trouble codes DTC C0000 DTC C0475 DTC C0476 DTC C0545 DTC C0847 DTC C0848 DTC C0896 DTC C0899 DTC C0900 Chevy Cobalt Trac Light On Harsh Shifting and NO COM All Modules Your saturn is the same as the cobalt . You have a computer problem or serial data network .

2003 saturn ion wont turn over at all dont even get the usall starter clicking just one click every once in awhile

How to voltage drop test starter motor circuit Looking at a wiring diagram an testing the starter circuit with a DMM - digital multi-meter is the way to find the problem . Free wiring diagram's here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size. Under system click on engine then under subsystem click on starting . Click the search button then the blue link . Looking at the diagram you will see this starting circuit is computer controlled . Ignition switch is a low voltage input to the BCM - body control module. A message to the ECM - engine computer from the BCM requesting a start over the serial data network (class2) will energize the relay sending B+ voltage to the S terminal on the starter solenoid . Your best bet mite be to have it towed to a qualified repair shop.

The Saturn Ion randomly will

Something to do with the PASSLOCK system - anti-theft . Loose passlock sensor or key . Thing's do wear out after time . The passlock sensor is part of the ignition lock cylinder housing .There is also a magnet in the lock cylinder an when you turn the key the magnet rotates past the sensor causing a voltage signal that the module in charge (BCM) reads ,worn or sloppy fitting parts are probably the problem . Your vehicle is 14 years old , just think of how many times the key was stuck into the ignition switch an turned . Don't know of any by-pass fixes for this , look on line . Or you probably would have to replace the whole lock an lock cylinder .
