Engine Options 1995:

Likely includes the 2.0L Twin Spark (16-valve I4), possibly the 2.0L Turbo (16-valve I4), and the 2.5L V6 (12-valve). The 1.7L and 1.8L engines may also be present in earlier 1995 models or specific markets.

2.0L Twin Spark (16V) Approx Power:

150 PS (148 hp; 110 kW)

2.0L Twin Spark (16V) Approx Torque:

187 Nm (138 lb-ft)

2.5L V6 (12V) Approx Power:

166 PS (164 hp; 122 kW)

2.5L V6 (12V) Approx Torque:

220 Nm (162 lb-ft)

Fuel Delivery:

Bosch Motronic electronic fuel injection (EFI) for most variants, potentially a Weber Marelli system for some engines.

Coolant Type:

Glycol-based antifreeze (e.g., Paraflu UP or equivalent) with a mix ratio of 50:50 with distilled water is recommended.

🔧 Transmission

Transmission Type:

5-speed manual transmission was standard on most models. The Q4 models featured a 6-speed manual.

Transmission Options:

A 4-speed automatic transmission was optional on some non-Q4 variants.

Clutch Type:

Hydraulically operated, dry single-plate clutch.

Manual Transmission Fluid:

Typically API GL-4 or GL-5 gear oil, with viscosity grade 75W-90 or 80W-90. Specific Alfa Romeo part numbers or equivalents will be detailed in the manual.

Automatic Transmission Fluid:

ATF Dexron II or equivalent, as specified by Alfa Romeo for the period.

📐 Dimensions

Length:

Approx. 4,290 mm (168.9 in)

Width:

Approx. 1,700 mm (66.9 in)

Height:

Approx. 1,425 mm (56.1 in)

Curb Weight:

Tire Sizes:

Common sizes included 195/55R15, 205/50R16, and 205/45R17 depending on trim and model year.

🛡️ Safety Features

Crash Test History:

As a vehicle from the mid-1990s, official comprehensive crash test data from agencies like NHTSA or Euro NCAP may be limited or dated. The manual will likely detail structural integrity and safety-related components.

ABS:

Anti-lock Braking System (ABS) was available, particularly on higher trim levels and Q4 models. The manual will cover its operation and diagnostics.

Airbags:

Driver's side airbag was an option or standard on later models. Passenger airbags were less common for this era.

Seat Belts:

Front seat belts with pre-tensioners, rear seat belts. Detailed adjustment and replacement procedures are typically included.

💡 Technology Features

Audio System:

Original systems typically included a basic AM/FM radio with cassette player, with CD players becoming optional or standard on later models. Speaker configurations and wiring diagrams will be in the manual.

ABS Operation:

Details on how the ABS system operates, including component locations, sensor diagnostics, and hydraulic unit functionality.

Wiring Schematics:

Comprehensive wiring diagrams for all electrical systems, crucial for troubleshooting any electronic or connectivity issues.

🔧 Maintenance

Oil Change Interval:

Typically 10,000 km (6,000 miles) or 12 months, whichever comes first, for synthetic or semi-synthetic oil. The manual will specify the exact interval and oil type.

Spark Plug Replacement:

For Twin Spark engines, spark plug replacement is a critical maintenance item. Intervals vary, but typically involve replacing all four plugs and sometimes an additional coil plug (total of 8 per cylinder on early Twin Spark versions). The manual will detail the specific procedure and part numbers.

Timing Belt Replacement:

The timing belt and tensioners for the Twin Spark engines require replacement at regular intervals, often around 70,000-100,000 km (43,000-60,000 miles) or 5 years. Failure to do so can result in severe engine damage. The manual will specify the exact interval and procedure.

Engine Oil Capacity:

Approx. 4.0 - 4.5 liters (4.2 - 4.8 US quarts) for 2.0L engines, and slightly more for V6. The manual will list exact capacities for each engine variant.

Engine Oil Grade:

Recommended grades typically include 10W-40 or 5W-40, often API SJ/SL or ACEA A3/B3 specification. The manual will provide precise recommendations.

Twin Spark Issues:

Potential issues can include spark plug wear, oil consumption, and ignition coil failures. The manual's diagnostic section will be crucial for addressing these.

Rust And Corrosion:

Like many European cars of this era, rust can be an issue, particularly around wheel arches, sills, and rear valence panels. The body repair section will be valuable for addressing this.

Suspension Wear:

Bushings and ball joints in the suspension can wear over time, leading to a less precise feel and potential noise. The manual provides detailed specifications for replacement and alignment.

📚 Vehicle History
