Alfa Romeo Milano 75 1985-1992 Service Repair Workshop Manual PDF
The Alfa Romeo 75, marketed as the Milano in North America, was Alfas compact executive sedan produced from 1985 to 1992. Designed to replace the legendary Giulietta and Alfetta, the 75 featured a distinctive wedge-shaped profile and rear-wheel drive layout with a de Dion rear suspension setup for refined handling. The 75 was the last Alfa Romeo to use the longitudinal drivetrain layout with the transaxle at the rear, a hallmark of the marques sporting engineering heritage.
Engines ranged from economical four-cylinder Twin Spark units to the legendary Busso V6 in various displacements. The Quadrifoglio Verde variants delivered genuine sporting performance that earned the 75 respect among enthusiasts. The Milano 75 remains a cult classic with strong parts support and an active community of specialists.
VEHICLE/EQUIPMENT INTRODUCTION:
The Alfa Romeo 75 Milano occupied the compact executive segment and carried forward Alfas tradition of sporting sedans with unique engineering solutions. The rear transaxle layout provided near-perfect weight distribution and the de Dion rear suspension delivered excellent tire contact during cornering. The range included 1.6, 1.8 and 2.0 Twin Spark four-cylinder engines and 2.0, 2.5 and 3.0 liter Busso V6 units. The Twin Spider inlet manifold design on Twin Spark models and the distinctive Alfa sound from the Busso V6 exhaust made these engines memorable. The 75 competed with the BMW 3 Series and Mercedes 190 but offered more character and individuality.
