Crash Safety Context:
Vehicle design predates modern stringent crash safety standards. Structural integrity and passive safety features reflect early 1980s automotive design.
Active Safety Features:
Front disc brakes, rear drum brakes. Dependent on specific model year and trim for features like power-assisted steering.
Passive Safety Features:
Seat belts (typically front inertia reel), padded dashboard, safety glass.
Oil Change Interval:
Typically every 6,000 miles or 6 months, whichever came first. Check manual for specific engine.
Spark Plug Replacement:
Approximately every 12,000-18,000 miles, dependent on plug type.
Engine Oil Type:
API SF/CC or SG/CD, SAE 20W/50 or 15W/40 (check specific manual for ambient temperature range and exact spec).
Coolant Type:
Ethylene glycol based antifreeze with corrosion inhibitors. Typically 50% antifreeze / 50% water mixture. Refer to manual for specific formulation.
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid (check manual for specific requirements).
Gearbox Oil Type Manual:
GL4 hypoid gear oil, SAE 80W/90 (check manual for specific grade and capacity).
Hydragas Fluid:
Proprietary Hydragas fluid, typically a mix of distilled water and alcohol-based anti-freeze. **Crucially, DO NOT mix with Hydrolastic fluid.**
Common Rust Areas:
Wheel arches, sills, door bottoms, boot floor, suspension mounting points are prone to corrosion.
Hydragas Suspension:
Hydragas suspension units can lose pressure over time, requiring recharging. Diaphragm failure is also a possibility.
Carburetor Issues:
Carburetors (especially SU) can require regular tuning and are susceptible to wear and gumming if not maintained.
Electrical Gremlins:
Older wiring looms and connections can be prone to corrosion and high resistance, leading to intermittent electrical faults.
Austin Rover Group:
Part of the Austin Rover Group, inheriting the legacy of British Leyland's passenger car division.
Metro Development:
Developed as a successor to the Morris Marina and Austin Allegro in the small car sector. Famous for its Mini-derived front-wheel-drive transverse engine layout.
Production Locations:
Primarily produced at the Longbridge plant in Birmingham, England.
Production Period:
1980 - 1990
