Spark Plug Removal Tool for the 2010 Smart 451

Model: Smart Smart 451 - Years 2007-2015
Part: Key

As seen in the video from minute 16:40, we will cover the removal of the spark plugs from our Smart. Once you locate the three coils, apply slight pressure with a screwdriver to detach the clip, and then unscrew the bolt using a ratchet spanner. After removing the first coil, proceed with a correctly sized spanner, an extension, and a ratchet to extract the spark plugs. Reverse the procedure for reassembly by inserting the spark plugs, reattaching the coil, and securing the previously detached clip.
