Anybody know the size of the 5 torx bolts that hold the coil pack on an 04 1.8 ls? Im still in the process of sorting a set of specific service tools for the Vectra. Ive done oil and filter, airfilter and its plugs next (i dont like the extremely long intervals of the Ecoflex schedule - spark plugs every 80,000!!!!!). I must say , this site is extremely helpful so thanks for any input. By the way, i didnt receive any carpass or codes with my Vectra - will a dealer charge for this if i need it in the future? Im very pleased with the car - terrific motorway cruiser and nice looking. Thanks again for any suggestions.
