Smart Fortwo 451 lambda probe disassembly instructions

Model: Smart Smart 451 - Years 2007-2015
Part: Oxygen sensor

In this tutorial we will see the instructions that will allow us to remove the lambda probe, or the oxygen sensor, on a Smart Fortwo 451. Our sensor is placed on the catalyst of our muffler, which we find on the back; to access it comfortably it will be necessary to remove the rear bumper. Once disassembled we go to identify our lambda probe and with a wrench we go to unscrew it; after having removed it, disconnect the electrical connector of the sensor and replace it with the new one. We just have to screw first by hand and then tighten with the key and reconnect the electrical connector!

How to Install Roof Bars on a Fiat 500X

Learn how to equip your car with universal roof bars. Universal roof bars are used on cars with and without roof rails (fixed bars secured to the car roof). Install the roof bar kit as shown in the video with the bars calibrated according to the width of the car. Position the brackets at both ends of the doors on the car's original roof rails. Once the width of the anchoring brackets is adjusted, tighten the bolts with the butterfly nut (if a lock is present) until fully secured to the roof rails. Finally, apply the safety caps on your Fiat.
