Alfa Romeo 156 Service Manual
VEHICLE/EQUIPMENT INTRODUCTION:
The Alfa Romeo 156 was a compact executive sedan produced by the Italian manufacturer from 1997 to 2007. Designed by Walter de Silva, the 156 was widely praised for its distinctive styling with hidden rear door handles and a dramatic sloping roofline. Under the hood, the 156 featured a range of Alfa Romeo engines including the celebrated Twin Spark 16-valve four-cylinder with variable valve timing, a 2.5-liter V6 Busso engine considered one of the finest sounding production V6s ever made, and several JTD common-rail diesel options. The 156 Sport Q4 variant featured an attractive all-wheel-drive system. Handling was characterized by precise steering and firm suspension tuning true to Alfa Romeo sporting heritage.
