OXYGEN SENSOR REPLACEMENT GM 3.8l V-6 SERIES 2 (BANK 1 SENSOR 1)

Описание: In this video I'll show you how to replace an O2 sensor on a GM 3.8L v-6 series 2. While this video fits in a lot of different GM models and years the particular vehicle that is shown in the vehicle is an 01 Pontiac Bonneville. The procedure for your vehicle will be similar but may not be exactly the same, so a repair manual would be suggested.

The particular O2 sensor is Bank 1 sensor 1 and it is located on the back side of the engine on the exhaust manifold just beneath the heater hoses. Note: that some V-6 engines may have Bank 1 and Bank 2 O2 sensors so refer to your repair manual for correct locations. This vehicle only has a Bank 1 sensor 1 O2 sensor and an Bank 1 sensor 2 O2 sensor and for this year the location noted in this video for Bank 1 Sensor 1 is correct.

The "special" O2 sensor socket is a 7/8" socket with a slit up the side. As far as I know they only come in one size.

Warning!! Be sure the vehicle is totally cooled down before doing this. The exhaust manifold gets extremely hot and can severely burn you. Give the engine at least 2 hrs cool down time (time not running).
