get a O2 sensor socket and do it just like a spark plug. Make sure the engine is at normal operating temperature though, if not you might damage the manifold.
Sadly, its not too easy. With my 97 SS, i have dual cats so i have 4 O2's total. Im not sure about your 95, but when you get to it, be sure to have a LOT of extensions (access is really tight) and have a few breaker bars/pipes to turn the rachet.
Exhaust system.
It has 2 of them.
where are the oxygen sensors on a 2000 Pontiac grand am and how do you change them?
where are the oxygen sensors on a 2004 ford escape with a 3.0 engine
The 2002 Pathfinder oxygen sensors are critical part of the engine management system. You can find the oxygen sensors in the exhaust system.
no just the precat as the latter does not really change or affect how the engine runs
A 2007 Durango has four oxygen sensors.
The oxygen sensors are screwed into the exhaust pipe behind the engine.
oxygen sensors are located just forward of your engine. In front of the engine is the catalytic converter. At the top at the bottom are your oxygen sensors.
no xoygen sensors on diesels
The oxygen sensors are screwed into the exhaust on the rear of the engine.
There are two oxygen sensors screwed into the exhaust on the rear of the engine.
