Engine Options Common:
1.4L (C14SE), 1.6L (C16NZ, X16XEL), 1.8L (C18NZ, X18XE), 2.0L (C20NE, C20XE 'Redtop', X20XEV), 2.5L V6 (C25XE, X25XE).
Power Range:
Approximately 75 hp (C14SE) to 204 hp (Calibra Turbo 4x4, C20LET).
Torque Range:
Approximately 115 Nm to 280 Nm (Calibra Turbo).
Fuel Injection:
Multi-point fuel injection (MPI) or indirect fuel injection (CIS-E) for most gasoline engines. Turbocharged engines feature advanced fuel injection.
Fuel Type:
Unleaded gasoline (Petrol).
Valvetrain:
SOHC (Single Overhead Camshaft) or DOHC (Double Overhead Camshaft), typically 8 or 16 valves per engine.
Crash Test Results:
Euro NCAP and ADAC testing generally showed competent safety for their era, though modern standards are significantly higher. Specific ratings for these years are less standardized than today.
ABS:
Anti-lock Braking System (ABS) was an option or standard on higher trims.
Traction Control:
Traction Control System (TC) was available on some performance models, especially AWD variants.
Airbags:
Driver's airbag became more common through the covered years. Passenger airbags were less common or optional.
Seatbelts:
Pre-tensioned seatbelts were available, particularly in later models.
Oil Change Interval:
Typically every 10,000-15,000 km or 12 months, depending on driving conditions and oil type used.
Timing Belt Replacement:
For engines with timing belts (e.g., C14SE, C16NZ, C20NE), replacement is typically recommended every 60,000-90,000 km or 4-5 years.
Engine Oil Specification:
API SG or higher, SAE 10W-40 or 15W-40 commonly recommended. Specific viscosity may vary with climate and engine variant. Check manual for exact OEM spec (e.g., GM-LL-A-025).
Coolant Specification:
Ethylene glycol based antifreeze, typically a G11 type (blue or green). Mix ratio 50:50 with distilled water.
Brake Fluid Specification:
DOT 3 or DOT 4 brake fluid.
Transmission Fluid Manual:
GL-4 rated gear oil, SAE 75W-90 or 80W-90.
Transmission Fluid Automatic:
Dexron-II or Dexron-III ATF (Automatic Transmission Fluid).
Electrical Gremlins:
Common for older European cars; issues with wiring harnesses, sensors, and control modules can arise.
Rust Corrosion:
Vulnerable areas include wheel arches, sills, and the subframes. Regular inspection and treatment are crucial.
Suspension Wear:
Bushings, ball joints, and tie rod ends can wear over time, leading to poor handling and noise.
Cooling System Leaks:
Radiator, hoses, and water pump can develop leaks.
Power Steering Pump:
Leaks or failure of the power steering pump or rack can occur.
Opel Legacy:
Opel, a German automaker with a long history dating back to 1898, is known for producing reliable and practical vehicles for the European market.
Vectra A Generation:
The Vectra A (J/T body) replaced the Opel Kadett E (as Vauxhall Astra and Opel Kadett) in the family car segment. It was a significant step up in size and refinement.
Calibra Development:
The Calibra was essentially a coupe version of the Vectra A platform, designed by GM's European design studio. It was lauded for its exceptionally low drag coefficient (Cd of 0.26).
Manufacturing Locations:
Primarily produced in Germany (Rüsselsheim) and also in the UK (as Vauxhall Cavalier/Calibra) and other GM facilities.
