SKODA 120LS 120LSE 1976-1990 SERVICE REPAIR WORKSHOP MANUAL
VEHICLE/EQUIPMENT INTRODUCTION:
The Skoda 120LS and 120LSE are rear-engine, rear-wheel-drive sedans manufactured by the Czechoslovakian automaker AZNP in Mlada Boleslav. Part of the Skoda Type 742 series, these models were produced from 1976 through 1990 and exported to markets across Europe and beyond. The rear-mounted ohv water-cooled inline four-cylinder engine driving the rear wheels provided a layout similar to contemporaries like the Volkswagen Beetle and Fiat 126.
The 120LS denoted the higher equipped luxury specification with improved interior appointments while the 120LSE added even more creature comforts. Both models featured the same robust 1174cc aluminum alloy engine with overhead pushrod valve gear, four-speed manual transmission, and simple, durable mechanical systems that were straightforward to maintain.
Today these classic Czech automobiles are gaining recognition among vintage car enthusiasts who appreciate their simple mechanical design, low running costs, and the charm of rear-engine dynamics.
