There are 2 of them on this vechicle, (one off of each cylinder bank) they're located just below the engine exhaust manifolds.

Loss power wont start maybe exhaust or catltic ?


I had a chevrolet cavalier once that had a clogged exhaust. i was driving and the catalytic converter fell apart, and clogged the exhaust system. I completely lost power, and barely got home. Try getting your arm under the car, and hit the catalytic converter with your had, or a mallet. If it has fallen apart and failed, you should hear a clattering sound. Try inspecting the whole exhaust system, looking for bends in the exhaust pipes. When my catalytic converter failed, i also heard a hissing sound when it was running, and the engine was slightly overheating because of the restriction in the exhaust.
!!GOOD LUCK!!

Is there a diagram anywhere online for a 1993 Nissan Altima that shows where the catalytic converter is and how it connects to the exhaust system?


The catalytic converter is located appx. underneath the front passenger's seat, on the exhaust pipe. It's smaller than the muffler and squarish in shape. It bolted onto the exhaust pipe. There is only one exhaust pipe on that car and also only one catalytic converter.

What are the torque specs for 1996 Buick Century 3.1 L intake manifold?


Front Pipe REMOVAL & INSTALLATION Pipe Without Catalytic Converter
  1. Before removing any component of the exhaust system, always squirt a liquid rust dissolving agent onto the fasteners for ease of removal..
  2. Raise and support the front of the vehicle on jackstands.
  3. Remove the exhaust pipe-to-manifold nuts.
  4. Support the catalytic converter, then disconnect the pipe from the converter. Remove the pipe.
  5. Remove the exhaust gaskets. To install:
  6. Be sure to use all new gaskets when required. Assemble the system, check the clearance and tighten the bolts to about 15-30 ft. lbs. (20-41 Nm). Fig. 1: Front exhaust pipe connection common on vehicles with the catalytic converter not included 86813320.gif

  7. All clamps should be tightened to about 18-25 ft. lbs. (24-34 Nm). Do overtighten the clamps. If pipes become dented they can leak.

How do you know if your cat converter is going bad? Can you test for it?


There are two ways a converter can fail:
  • It can become clogged.
  • It can become poisoned.
There really is no "inspection port" for the consumer or mechanic to see an actual clog in a converter. Often, the only way to tell if a catalytic converter is malfunctioning (plugged) is to remove it and check the change in engine performance. When a clogged converter is suspected, some mechanics temporarily remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance.
A catalytic converter relies on receiving the proper mix of exhaust gases at the proper temperature. Any additives or malfunctions that cause the mixture or the temperature of the exhaust gases to change reduce the effectiveness and life of the catalytic converter. Leaded gasoline and the over-use of certain fuel additives can shorten the life of a catalytic converter.
A catalytic converter can also fail because of:
  • Bad exhaust valves on the engine
  • Fouled plugs causing unburned fuel to overheat the converter
­Sometimes you can tell that a converter is clogged because you don't go any faster when you push the gas pedal. Also, there usually is a noticeable drop in gas mileage associated with a clogged catalytic converter. A partially clogged converter often acts like an engine governor, limiting the actual RPMs to a fast idle. A totally clogged converter causes the engine to quit after a few minutes because of all the increased exhaust back pressure.
The catalytic converter, like the rest of the emissions system, typically has a warranty length that exceeds the term of the warranty for the rest of a typical U.S. automobile.
Here is a safety reminder: Do not park your car over tall grass or piles of dry leaves. Your car's perfectly running catalytic converter gets very hot -- enough to start fires! You can keep it running well by keeping the ignition system in top shape, to prevent any unburnt fuel from entering the catalytic converter.

Where in the engine is the catalytic converter


The catalytic converter is part of the exhaust system and is usually found under the vehicle, and the exhaust will run from the exhaust manifold to a pre-catalytic converter, and then down to the catalytic converter, and then the exhaust will run from the catalytic converter to the exhaust muffler, and then continue out to the end of the tail pipe.
I have provided an image of the catalytic converter to help assist you.

Oxyogen sensors how many and where are they


There should only be two, they are screwed into the exhaust pipes,
One up near the engine, and the other one down by the catilytic converter. Both have wire connectors on them.

I need to know where the oxygen senor is locate at


There will be one located before your catalytic converter and one after your catalytic converter for each exhaust system you have.
In some cars, there can be 2 O2 sensors before the catalytic converter even if there's only one exhaust system.

Bank 1 will refer to the sensor that's on the same side as cylinder 1 and Bank 2 will mean the opposite side.

Sensor 1 will refer to the sensor before the catalytic converter and Sensor 2 will mean the one after the cat

How to replace/remove both catalytic converters


Below are the steps needed to remove the catalytic converters. You may be able to first remove the band clamp from between the converter and the exhaust manifold, then loosen the rest of the system and to get enough clearance to slide the converter towards the front of the vehicle but you will need to first remove the clamp that holds the converter to the rest of the exhaust. Hope this helps
_______________________
Both Catalytic Convertors

First you need to raise the vehicle.

Next, you need to pry the insulators from the support brackets and support the muffler and tailpipe with jackstands.

Then, loosen the the catalytic converter down pipe-to-front resonator clamps and separate the front resonator from the converter down-pipes. Carefully lay the free laying exhaust on the ground.

______________________
Right Catalytic Converter

Then, remove the down-pipe-to-transaxle bracket nut, loosen the clamp and separate the extension pipe from the converter.

Next lower the vehicle and remove the air filter and intake ducts. Disconnect the wiring harness for the O2 sensor and the remove the sensor.

Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment. You may need to replace these clamps after removal because you need to pry it apart and they will leak when you reinstall.

_____________________
Left Catalytic Converter

Now disconnect the wiring harness for the O2 sensor and the remove the sensor.

Next remove the down-pipe-to-transaxle bracket nut

Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment.
