Where is the upstream oxygen sensor located and can you replace it yourself?

The upstream o/2 sensor is located in the exhaust system between the exhaust manifold and the catalytic converter. Some vehicles will have 2 upstream sensors (i.e. 1999 Chevy astro 4.3l engine has sensor for left exhaust manifold and another for right exhaust manifold). I am trying to find out for sure if you have to replace both when one goes bad. Bosch says both must be replaced!!!??? Oh yeah it(they)are easy enough to replace if you can see it (them).

HOW on a 94 Chevy Beretta do I remove the radiator fan If I remove the bolt and lift the fan it won't clear the exhaust manifold?

Remove your lower passenger side engine mount and you will be able to rock the engine back far enough for the fan to clear the manifold.


Can vibration cause itch?

yes, A vibration with a frequency high enough to cause itching


Is it hard to change exhaust manifold?

This largely depends upon the condition of the mounting studs. If they are clean, it's easy; if they are bad enough, they might require cutting off and new studs.


How do you change exhaust headers on Saturn sl2?

It would probably be best to remove the radiator fan and radiator, to give you a little more working room. Then remove the bolts that hold the exhaust manifold to the headpipe. There are several bolts and/or studs with nuts that hold the exhaust manifold to the engine head, remove them, saving one of the center bolts/nuts for last. You may need to remove the AC compressor, but don't disconnect the refrigerant lines if you do; just set the compressor somewhere out of the way. Once all of the bolts and nuts have been removed, just gently work the exhaust manifold loose and pull it off. Clean all surfaces. The gasket between the head and the exhaust manifold will stick in places, causing some inconvenience as you remove it. Don't nick the head as you clean it, that can result in a place for hot exhaust to leak out and will result in eroding away part of the head and you'll end up with an even larger exhaust leak. Find a good technical reference book to get the proper torque settings for the exhaust manifold bolts/nuts. If you over tighten, they will pull out of the head. If you do not tighten enough, they will work loose. Use a NEW doughnut gasket between the header and the head pipe.


How can you make loud exhaust sound louder?

Attach a bigger sports exhaust, simpler enough


Why do subwoofers vibrate you?

Sound is vibration of the air that we detect mostly with our ears. When the sound (vibration) gets to low enough frequencies and is strong enough it vibrates other things, like the walls, floor, furniture, and us!


Can you circulate your exhaust to your air intake to act as a supercharger for your truck?

No, exhaust does not have enough oxygen in it for the engine to run.


Can you really suck a valve if you run an engine with no exhaust?

Not sure what "suck a valve" means, but running an engine with no exhaust could easily cause the exhaust valves to get hot enough to melt. Exhaust valves get very hot and if you just shut off the engine with no exhaust manifold in place the cold air can cause an exhaust valve to warp, then,next time you run the engine it will not seat properly.Many people don't understand and assume that if ANY part of the exhaust system is missing you can warp a valve but that fear is just the result of failing to understand the root cause of the problem. On the other hand, a lean burning engine can overheat the valves to the point that the metal can become soft.
