Ethylene glycol-based antifreeze, typically pink or blue. Specific Alfa Romeo approved or equivalent. Manual will specify type and concentration.
Twin Spark Issues:
Oil consumption, potential for oil contamination in spark plug wells (due to seal degradation), wear on camshafts, timing belt failure if not replaced on schedule.
Electrical Issues:
Can experience issues with wiring harnesses, sensor failures, and minor electrical gremlins typical of European cars of this era.
Rust Corrosion:
While generally better than earlier models, underbody rust can be a concern in certain climates. Manual will likely detail areas to inspect.
Brand Philosophy:
Alfa Romeo is renowned for its sporting heritage, distinctive Italian design, and driver-focused engineering, often referred to as 'Alfasud' heritage for its front-wheel-drive platforms.
Generation Development:
The 145 and 146 were developed on a platform derived from the Alfa Romeo 33 and Sud, marking a significant shift to front-wheel drive for Alfa Romeo's compact offerings. The 145 featured a distinctive 'hatchback coupe' styling, while the 146 offered a more conventional five-door layout. Minor updates and engine revisions occurred throughout their production run.
