Fuel System Types:
Carburetor (e.g., Pierburg 2E2, Solex) on early models, Single-Point Injection (SPI) and Multi-Point Injection (MPI) on later models. Diesel variants were also available with direct injection.
Service Intervals Engine Oil:
Typically every 6,000-12,000 miles or 12 months, depending on engine type and driving conditions. Refer to specific engine recommendations in the manual for precise intervals.
Service Intervals Filters:
Oil filter: Replace with oil change. Air filter: Replace every 12,000-24,000 miles or as needed based on inspection. Fuel filter: Replace every 24,000-36,000 miles or as specified.
Timing Belt Replacement:
Typically every 40,000-60,000 miles or 4-5 years for interference engines, or as specified in the manual for specific engine codes. Failure to replace can result in catastrophic engine damage.
Engine Oil Specification:
API SF/SG or ACEA A1/A2. Viscosity grades typically SAE 10W-40 or 15W-40, with SAE 5W-30 or 10W-30 recommended for colder climates. Exact specification depends on engine and manufacturer recommendation.
Coolant Specification:
Ethylene glycol based antifreeze/coolant, typically a 50/50 mix with distilled water. Specific OAT or HOAT coolants may be required for later models. Refer to manual for OAT/HOAT type. (Example: Vauxhall GM Green coolant).
