When car is running you hear a clicking noise. Almost as if you put a playing card to a childrens bike. I have a 2000 Saturn SL2. I'm almost sure its the head gasket because there is coolant all over.

if it is a cable clutch ,replace the cable as it is not allowing the clutch to engage
If it is hydraulic operation , replace the clutch master cylinder

Check coolant temp sensor.

One Wire From Starter Motor Goes To Solenoid And Other Goes To BATTERY. Starter GETS 12 VOLT SUPPLY FROM BATTERY AND WITH THESE VOLTAGE IT TURNS THE MOTOR AND THIS TRIGGERS THE STARTER SOLENOID AND YOUR VEHICLE RUNS.============

Sounds like your timing is off. Could be your timing belt is off or your distributor is off.
Both are tricky to work on. Might even be one of the fly wheels are out off sink.
If your lucky and it's the distributor all you need to do is start the car, loosen the bolts just a little,
enough to turn it, than turn it by hand .But DON"T turn it to much.
You can use your ear to hear the difference when turning. Only need to turn it a fraction of an inch at a time to hear the difference.
Hope this help and good luck.

hows the fluid in it? make sure the fluid is topped off

Maybe the wrong one was replaced,these are tricky sometimes it sounds like the rightside but is really the leftside or the bearing was installed wrong or the bearing is not the noise, the best way is to get it on a lift and run it in drive and try to pinpoint the noise.

My car was doing this pretty bad and I changed the engine coolant temp sensor and it fixed my problem. Hope this helps!!

You need to replace the heater/AC blower motor the motor shaft bearing is defective..

You put the key into the lock cylinder, the lock cylinder is directly attached to the ignition switch. Both are inside the plastic boot around steering column.

Wiper motor is the problem,the park mode iside the motor logic is bad.The wiper motor will have to be replaced to correct concern.hope this helps
