You need to unclamp the "C" spring clamps from the manifold. This requires a special tool to expand the clamp. The clamp and gasket kit is around $100.Answer
No "special" tool is needed; simply visit your local Ace hardware or auto parts store and buy two exhaust clamps: Simple, all you really need to do is design a wedge that will spread the clamp wide enough to fit over and in place, then you bang the wedge out. OR First, use a jack to hold the exhaust pipe in place, put the top part of the C clamp on first then pull down with a chain or rope. Drivers side clamp on first cause its easy to get the first clamp on. As for the passenger side clamp, u gonna need some MUSCLE.
Do the same as the first, but your gonna need something stiffter than a chain, like a flat bar with a point on it that'll fit through the hole.
The catalytic converter will be underneath the car in the exhaust system directly after the pipe that connects the header (exhaust manifold (connects engine to the rest of the exhaust)) to the Cat (catalytic converter). there will also be a resonator that is closer to the muffler end of the exhaust. The cat has an O2 sensor in it so you'll know if you get the right one.
It is part of the exhaust system. It can be anywhere between the exhaust manifold and the muffler. It is usually half way between the manifold and the muffler. Some cars have two. The purpose of the converter is to change the carbon monoxide in the exhaust to sulfur dioxide. Carbon monoxide is a greenhouse gas and sulfur dioxide is not.
There are no tricks. It is part of the exhaust manifold.There are no tricks. It is part of the exhaust manifold.
Its called a catalytic converter. The American car company "Cadillac" does not manufacture converters for our vehicles. Remove it using two 14mm sockets. It is after the exhaust manifold down pipe and the exhaust system.
no. the catalytic converter system is there for a reason. it is reducing the impact of emissions on the environment.yes. you can but your vehicle may not pass emission standards in your state check before you remove it.
There are two sensors. One before the catalytic converter and one after. The first is at the back of the engine block on the manifold. It screws into the manifold and takes a special socket to remove (costs about $10). The second is between the converter and the muffler under the car. Its on top of the exhaust pipe and nearly impossible to change unless you take apart your exhaust system There are two sensors. One before the catalytic converter and one after.

check on the exhaust manifold and the catalytic converter. there are possibly 2 O2 sensors. unplug them and unscrew them with a wrench or buy a socket for an O2 sensor.
The O2 sensors are located on the exhaust of the vehicle. The first O2 sensor will be located beyond the manifold and before the catalytic converter, then there is typically one or more beyond the catalytic converter. to change them you have to unplug the wire at the connecter (generally about 6" from sensor) then simply unscrew them with a wrench out of the exhaust pipe. they may come out hard from repeatedly being heated and cooled.
Under the vehicle, the manifold connects to a "head pipe", and the head pipe connects to a device that just looks like a mufler, but it's not. That's the catalytic converter.
The catalytic converter is a sealed unit and must be replaced completely. A good mechanic or a shop that specializes in exhaust systems can do the job. If the entire exhaust pipe doesn't need replacing, the converter itself can be cut out of the existing exhaust pipe and a new one fitted in.
You have 2 sensors. The pre-converter O2 senser is located in the exhaust manifod ahead of the catalytic converter. The post-converter O2 sensor is located in the exhaust pipe after the catalytic converter. * Let the exhaust system cool. * Raise and secure the vehicle. * Disconnect the electrical connector from the sensor * Using a suitable wrench or special oxygen sensor socket, unscrew the sensor from the exhaust manifold or exhaust pipe. * Use some anti-seize compound on the threads of the sensor so that you can easily change them in the future. * Install the sensor and tighten. * Reconnect the electrical connector for the sensor and lower the vehicle
The easiest method is to remove it, and plug the ports on exhaust manifolds and catalytic converter.
after the rear cat assy is removed.what is the procedure to remove the cat on the firewall side at the manifold?
The catalytic converter is usually held in place by a set of clamps located at the front and rear of the unit. These clamps tie the unit to the exhaust system. If your converter is welded to the exhaust pipes, you will need to remove the old welding and weld the new one in place, or bring it to a service station and have them do it.
Oxygen sensors are usually located on the exhaust just after the exhaust manifold and just ahead of the catalytic converter Depending on model as some have one sensor, some have two and some have four of them, I would look just before and just after the catalytic converter. The sensor reads oxygen content and reports back to the Powertrain control module (computer) the one before and the one after have a different reading as the converter changes the content. The PCM evauluates and change the fuel air mixure to correct.
Oxygen sensors require a special socket, unless it is easily accessible to get a 7/8 open end wrench on the sensor. This depends on which engine is in your car. There are several sensors depending on engine size in the exhaust manifold and the exhaust pipe before and after the catalytic converter.
A Catalytic Converter can fail if it becomes clogged or poisoned but there is no way of knowing when it is clogged. Replace your Catalytic Converter when it starts to malfunction.
You will need to remove the exhaust manifold retaining bolts in your 1993 Chevy Astro. Remove the exhaust manifold. Remove the exhaust manifold gasket and clean the surface. Reverse the process to install the new exhaust manifold gasket.
Working on the exhaust system is a job best left to a professional. You will save very little by doing it yourself. Have the catalytic converter tested to be sure you need a new one. Catalytic Converters are very expensive so you do not want to replace a good one. If it is bad you need to find out why it went bad. Things like a miss on a cylinder from a bad plug or a defective O2 sensor will ruin the converter. Also a burnt exhaust valve will destroy the converter.
First, park your vehicle in a level place and jack it up at all 4 wheels, allow the exhaust to cool down, remove the oxygen sensor from the catalytic converters and the bolts as well. Then put the new converter in place, tighten the bolts, and screw the oxygen sensor back. Lastly, test you catalytic converter, make sure there are no leaks.
It screws into the exhaust near the manifold. I haven't had to change mine on my intrigue, but if it's like others I've had to change, you get to it under the car behind the engine. Follow the exhaust from the catalytic converter up to the manifold, it should be the only sensor with a wire coming out of it that is screwed into the exhaust pipe. Unplug it from the wire harness, then unscrew it using a flat wrench. Have a new one ready to install, you can't run the car without it. Hope this helps.
Have you tried a new spark plug? Having same problem. It could be one of many things. Plugs, plug wires, distributor cap, rotor, or coil pack. It could also be but rarely, the EGR valve, or a plugged catalytic converter. If you smell rotten eggs in the exhaust, I would change the catalytic converter. Had the same problem it was because of an injector leaking into the manifold.
Only if it is not working.
There are TWO Oxygen sensors. One is located just in front of the catalytic converter, either on the exhaust manifold, or screwed into the inlet area of the catalytic converter itself. The second one is located either at the exhaust end of the catalytic converter or in the exhaust pipe directly after it. CAUTION: The electrical wires are permanently connected to the sensor and must not be removed from it, or it will be destroyed. Due to the constant changing temperatures to which they are subjected they may be DIFFICULT to remove. NOTE: There is a special tool designed for their removel - use of an open end wrench may round off the hex head. Start and run the engine for a minute or two (to slightly expand the metal of the exhaust system) and then, using caution not to burn yourself, carefully remove the sensors from their seat.
