1990 Alfa Romeo 33 Nuova Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The 1990 Alfa Romeo 33 Nuova represents the later evolution of Alfa Romeo compact front-wheel-drive hatchback range. Built on the Tipo 905 platform the 33 Nuova featured updated styling and improved mechanicals over the original 1983 design. Alfa Romeo engineered the 33 with their signature flat-four boxer engines giving the car a distinctive character and low center of gravity uncommon in the European compact segment. The 1990 model year brought refinements to the interior build quality and driveline components addressing earlier reliability concerns. With its twin-cam boxer engines producing between fifty-five and one hundred horsepower depending on variant the 33 Nuova offered spirited driving dynamics wrapped in an attractive Giugiaro-influenced body. Alfa Romeo commitment to performance is evident in the sophisticated independent rear suspension with de Dion tube layout and the close-ratio five-speed manual gearbox.
