Didn't do them, I noticed the temperature creeping up and I couldn't hear the rad fan cutting in.
I followed the wires from the relay box and found them all chafed and broken.
2 hours with a soldering iron and that was all done.
Missus took it today and rang me to tell me 4th gear isn't working now. :bang::bang:
I don't think there's much left to go wrong on this bloody car!
