The catalytic converter is nothing more than a wide spot in the exhaust line with some specialized material that promotes the burning of any remaining hydrocarbons. They are easy to replace but usually don't need replacing unless your engine burns oil or you have been using leaded fuel.
FRONT CONVERTER IS INTEGRAL WITH MANIFOLD AND MUST BE REPLACED AS A UNIT.
On the catalytic converter or exhaust manifold On the exhaust manifold or catalytic converter
Bolted to the exhaust manifold.
The catalytic converter bolts to the exhaust manifold on the rear of the engine on a 1999 Chrysler Town and Country.
Disconnect the frontand rear o2 sensor electrical connectors. Separate the catalytic converter from the flex-pipe. Remove the fasteners between the catalytic converter and the exhaust manifold. Disconnect the EGR tube from the catalytic converter. Remove band from the front of the catalytic that holds it to the bracket on the front of the engine block. Remove fasteners holding exhaust manifold to head.
The catalytic converter in directly behind the engine. ( might need to use a flashlight ) It is bolted right to the exhaust manifold. The catalytic converter in directly behind the engine. ( might need to use a flashlight ) It is bolted right to the exhaust manifold.
Your catalytic converter is at the top of your motor at the exhaust manifold take out the 4 14mm screws that connect your converter to your manifold drop down out the bottom of engine and replace another really simple fix
O2 sensors are usually on the exhaust manifold. Actually on the '96 Galant, one is in the header pipe (the pipe running below the engine between the manifold and the catalytic converter) and the other is in the catalytic converter.
There is one before the catalytic converter where the 4 runners meet on the exhaust manifold. And the second one is after the catalytic converter.
There are 2 oxygen sensors. The first is just after the exhaust manifold before it goes into the catalytic converter. The second is after the catalytic converter.
There are 3 oxygen sensors; one in the front exhaust manifold, one in the rear exhaust manifold, one AFTER the catalytic converter. The 2 exhaust manifold sensors are the same BUT the catalytic converter one is different. Also, the 2 exhaust manifold sensors have heaters in them, while the converter one doesn't.
The primary oxygen sensor is located before the catalytic on most Hondas depending on the year. If your Honda has the catalytic converter integrated to the exhaust manifold then you should find it on the manifold just before the catalytic converter.
The upstream sensor is screwed into the rear exhaust manifold. The downstream is screwed into the catalytic converter.The upstream sensor is screwed into the rear exhaust manifold. The downstream is screwed into the catalytic converter.
