🛡️ Safety Features

Safety Ratings Era:

Safety standards were less stringent than today. Likely did not undergo formal independent crash testing like Euro NCAP or IIHS in its launch year. Focus would be on passive safety features.

Active Safety Features:

Four-wheel disc brakes (on higher trims), ABS (Anti-lock Braking System) likely optional on higher trims or later models.

Passive Safety Features:

Seat belts (three-point inertia reel front and rear), Energy-absorbing steering column, Reinforced passenger compartment, Side-impact door beams (typical for the era).

💡 Technology Features

Infotainment System Era:

Basic for its time. Likely featured an AM/FM radio, cassette player, and possibly a CD player on higher trims. Speakers in doors and rear parcel shelf.

Driver Assistance Features Era:

Limited. ABS was an option. No advanced electronic stability control or traction control systems.

Connectivity Features Era:

N/A. Primarily mechanical and basic electrical systems. No integrated Bluetooth or USB ports.

🔧 Maintenance

Oil Change Interval:

Typically every 7,500 - 10,000 km (4,500 - 6,000 miles) or 6-12 months, whichever comes first, depending on driving conditions. Manual will specify.

Timing Belt Replacement:

Critical item. Typically every 60,000 - 90,000 km (36,000 - 54,000 miles) or 4-5 years. Manual will provide the exact interval and procedure.

Spark Plug Replacement:

Often around 30,000 - 40,000 km (18,000 - 24,000 miles) for standard spark plugs. Iridium/platinum plugs would last longer. Manual will specify type and interval.

Engine Oil Type:

API SG/SH or ACEA A2/A3 rated, SAE 10W-40 or 15W-40 depending on ambient temperature. Manual will confirm viscosity and API service classification.

Coolant Type:

Ethylene glycol-based antifreeze, typically mixed 50/50 with distilled water. GM Dex-Cool or equivalent might be suitable, but manual confirmation is key.

Brake Fluid Type:

DOT 3 or DOT 4 (typically DOT 3 for this era, but manual must be checked). Should be replaced every 2-3 years.

Transmission Fluid Type:

Manual: GL-4 SAE 75W-90 or 80W-90. Automatic: GM Dexron II/III or equivalent. Manual is essential for correct specification.

Common Issues Era:

Electrical gremlins, minor oil leaks, corrosion on body panels in certain climates, potential cooling system issues (radiator, hoses) with age, timing belt failure if not replaced regularly.

Timing Belt Criticality:

The engines used in the Espero are typically interference engines, meaning that if the timing belt breaks, severe engine damage (bent valves, piston damage) will occur. This makes timely replacement crucial.
