Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Specific OAT or HOAT not applicable for this era; use conventional green coolant.
Brake Fluid:
DOT 3 or DOT 4.
Power Steering Fluid:
ATF (Automatic Transmission Fluid) or specific power steering fluid as per manual.

Aging wiring harnesses and connectors can lead to intermittent electrical faults. Thorough inspection and potential repair/replacement are often necessary.
Transaxle Seals:
Potential for oil leaks from the transaxle or differential seals over time.
Timing Belt:
While Alfa twin-cams are chain-driven, some ancillary components might have belts. If applicable, refer to manual for replacement intervals. *Correction: The Alfetta twin-cam engines are chain-driven, which are generally more durable than belts but require tensioner checks.*
