1976-1990 Skoda 120 105S 105L Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Skoda 105 and 120 series, produced between 1976 and 1990, were among the most iconic vehicles from Czechoslovakias Skoda Auto company during the Eastern Bloc era. These rear-engine sedans and hatchbacks were derived from the Skoda 100/110 lineage and shared the same fundamental architecture: a rear-mounted, water-cooled inline-four engine driving the rear wheels. The 105S and 105L models featured a smaller 1046cc engine offering economical operation, while the larger 120 series used a 1174cc unit providing improved performance. The simple, robust mechanical design meant these cars were easy to service and repair, a trait that made them enduring favorites in Eastern Europe. The lightweight body, straightforward suspension layout, and uncomplicated electrics continue to attract classic car enthusiasts who appreciate the accessibility of these vehicles for restoration projects.
SERVICE & REPAIR SCOPE:
