Hi all, does anyone know the correct pattern for removing and refitting the head bolts on my Sei please. Going to attempt the obligatory head gasket change. Thanks in advance
Why?
The Seicento Technical Manual (the factory manual) is in the Downloads section. Download all 3 parts, stick them in one folder, use an unrar tool from Sourceforge to open them up. Takes minutes, and gives you just about everything you'll ever need.
Otherwise the Cinq Haynes will get you most of the way -- it's more convenient for lugging about.
Remember, a HG has either gone or it hasn't. If it hasn't gone, leave it alone (and only a compression test will tell you for sure it has).
If it has gone, it has probably gone for a reason (cooling fan malfunction, fubar water pump, fubar thermostat, water leak): if you don't fix the reason, it'll go again (and again, and again).
Makes sense to skim, replace timing belt, get valves re-cut, re-shim the valves, replace tensioner, water pump, etc. while you're at it. All adds up.
