Download your Service Manual for Fiat Palio/ Sienna/ Weekend G1 (< 2001 but depending on the problem or need information than can also be useful also for newer models) whit engines 1.4 SPI 8V, 1.6 SPI 8V, 1.6 MPI 16V and diesel, only in Spanish, HERE.
I would find this very useful - even in Spanish (!) but the extraction failed when using WinRar (in the Setup.exe file). Did anyone else get a good download and un-compression?
Thanks, Andy
