Renault Sandero K7m, 1.6 8v
Following a recent timing-belt change, I have put everything back together, fired her up and everything is peachy(so far).
But I have a left over bolt.
It is a torx bolt/screw, and I can't remember where it came from.
It was around the time I removed the plastic wheel arch. That plastic wheel arch is a bit of an enigma. Not least because there were a few connectors/bolts/screws missing when I started. Renault appears to have gone with the 'variety is the spice of life' approach when designing for the fasteners.
It is not the locking-pin bolt, which is also a torx bolt but much shorter, and it is not the top-bolt for the bracket covering the crank-pulley(that's also a torx-bolt).
