How do you cange the ignition coil on a fiat stilo?

Answer 1

Dead simple this one - just hope the answer has arrived in time to help! You will need either a Fiat star shaped screwdriver bit (or you can make do with a straight edged screwdriver), and a 10mm hexagonal socket. 1) Remove battery cover and disconnect the battery, this serves two purposes, firstly, it will prevent any accidental shorts, and secondly, the battery needs to be disconnected for at least an hour to reset the ECU. (This will also cancel/reset the "Engine Fault" message that appears on your dashboard, which is probably why you are here to start with!!) 2) Remove the engine cover, there are four 10mm nuts holding this in place. Once removed the ignition coils are in plain sight, and if you have the relacements you'll know what you are looking for. 3) Disconnect the lead from each coil, by firstly sliding back the yellow slide towards you, and then depressing the black clip into the gap in the yellow clip. 4) Undo the nut, which is holding the coil onto the housing, and then gently pull the coil out of its place sitting on top of the spark plug. 5) Insert new coil carefully, making sure that the rubber housing on the bottom of your coil, is in position over the spark plug, and push firmly into place. 6) Re-fix the bolt holding the coil into place, attach the lead puching firmly until it clicks, and push the yellow slide back into place. 7) Repeat Items 3-6, for the other coils, and replace the engine cover. 8) You'll probably need to go and make yourself a cuppa now, coz that'll only have taken about 30 minutes, and you need to make sure the battery has been disconnected for at least an hour, (I recommend 90 minutes, as nothing worse than having to start your hour again from scratch!) 9) Re-connect the battery, and replace the battery cover and the jobs done! Good Luck!!
