SOURCE: Have a 2003 Chevy Impala. Check engine light

Bank 1 is the rear O2 sensor, but experience says to change both. The front one is right behind the engine in the middle of the engine compartment. The rear O2 sensor is on the top of the exhaust pipe, just behind the catalytic converter. But the same code that shows it is the O2 sensor (which is P0420), is the same code for the catalytic converter, or a vacuum leak. Make sure if you do change the catalytic converter, ensure that the new one is OBD-2 compliant. And the vacuum leak could possibly come from the manifold gasket. Let me know what the problem was!

SOURCE: how do I service my A/C 2000 Chevy Impala LS

To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Both low and high side readings are lower than normal, this indicates a cars AC system is low on refrigerant and is under-charged.

If both low and high side readings are too high, this indicates an overcharged system - too much refrigerant. This also can indicate that the condenser fan is not working, is too slow or the car is overheating and heat is transferring from the radiator to the condenser.

If you are going to by the recharge kit at an Auto Parts store, With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the freon and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood. 
Good luck and keep me posted, be glad to answer more questions you may have.

It sounds like you might need to replace your motor mounts, or get a tier allignement done. The allignment you cannot do yourself but the motor mounts you can this requires you to place a jack under you engine and undoing the motor mounts then replace them and take away jack.

SOURCE: 2003 chevy impala ls starts then stalls

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.

Where are the 02 chevy impala 3.8L o2 sensor locations, I only see three. the top bank one sensor 1 is stripped out, how do i get that one out?


you can apply pressure to the sensor while undoing it to force it out or you will have to cut out the thread area and get an O2 sensor bung hole replacement at an auto supply store and weld into place and install a new O2 sensor. bank 1 sensor 1 is located in the front pipe off the manifold that has cylinder #1 on and bank 2 sensor 1 is on the side that cylinder #2 is on like sensor 1. sensor 3 is the one just before the cat.

I think it is located near the bottom of the oil pan on the back side, you will probably have to drain the oil but I'm not sure. That is where mine is located however mine is a 2000 Chevy Impala LS.

LINCOLN LS 2000 O2 SENSOR


vibration is not likely to be an O2 sensor

rarely will I ever see an failed O2 cause anything but bad gas milage and a check engine light

More likely would be bad spark plugs/wires and/or maintenance items like a fuel filter
