Where are the fuel filter and oxygen sensors on a 96' Geo Metro and how do you change and clean them?

Answer 1

The fuel filter will be located on the fuel line somewhere in between the engine and fuel tank on the underside of the vehicle, more than likely around the rear end.(look for a metal can with 2 metal lines coming out each end. Sorry i can't pinpoint the location. As far as the oxygen sensors, both will be mounted on the exhaust pipe. If it has two sensors, which i believe yours does, one will be mounted before the catalytic converter, and the other will be mounted after it. As far as cleaning, you can't clean any of them, they must be replaced. Be prepared to spend approx. $10 for the fuel filter, and Approx. $60-$70 for 1 oxygen sensor. By the way, it will NOT run better if you just unhook the sensors!! I hope I've helped..... I just got rid of my 1995 Geo Metro and it was a great car. Assuming you have a 3 cylinder with California emissions, the O2 sensor is right in the exhaust manifold and there is only one. You need to remove and replace the O2 sensor, not clean it. The fuel filter is up under the left side of the car in between the left rear suspension and the drivers door. You want to replace it also. It should be held to the body with a steel mounting bracket that is rusty and held on with a bolt. This can be a bugger. I suggest spraying the mounting bracket and bolt with WD40 and letting it soak a few minutes before trying to remove. Once you unbolt the bracket the whole bracket with the filter inside pops out of the car. Then you remove the filter from the bracket and fuel hose and install the new one. Reinstalling the bracket can be a little tight, but it will go back in. Also, make sure you remove the gas filler cap to relieve some of the pressure, it does make a difference. Good luck!
