g40 not sure of age of engine.. it came out coupe sure it was a H reg so 90/91 .?
vw parts reckon that theres two belts ?
ideally mate you need the reg it came off and they will tell you. cut off date was around 1992.
you can tell by looking - wide spaced flat teeth = early, rounded closer together teeth - late!!
do any g40s have the old square toothed cambelts?
