Standard Transmission:
4-speed or 5-speed manual transmission.
Optional Transmission:
3-speed automatic transmission (e.g., C3, ATX) or 4-speed automatic.
Drivetrain Layout:
Rear-wheel drive (RWD) for most models, with some later models and performance variants offering Four-wheel drive (4WD/AWD).

Width:
Varies by body style, e.g., ~1700 mm for 5-door hatchback.
Curb Weight:
Approx. 1050 - 1350 kg depending on body style and engine.
Crash Test Ratings:
Euro NCAP ratings were not standard during the Sierra's primary production run. Later models may have some data available.
Braking System:
Front disc brakes, rear drum brakes (standard); ventilated front discs and rear discs on performance models (e.g., XR4i, Cosworth).
Suspension Geometry:
Independent front suspension (MacPherson struts), independent rear suspension (multi-link beam or trailing arms on many variants) for improved handling.
Seatbelts:
Standard three-point front seatbelts, two-point or three-point rear seatbelts depending on seat position and year.
Child Seat Anchors:
May feature early forms of child seat restraint systems, but not ISOFIX in the modern sense.
Audio Systems:
Basic AM/FM radio, cassette players, often with manual aerial adjustment. Higher trims might have graphic equalizers or better speaker systems.
Instrumentation:
Analogue gauges for speed, tachometer, fuel, temperature. Warning lights for oil pressure, battery, etc.
ABS:
Optional on many models, standard on higher trims and performance variants from the late 1980s onwards.
Connectivity Features:
Limited by era. Primarily mechanical and basic electrical systems. No modern Bluetooth or USB connectivity.
Oil Change Interval:
Typically 6,000-10,000 miles or 12 months, depending on engine oil specification and usage conditions.
Air Filter Replacement:
Recommended every 12,000 - 18,000 miles or as needed based on operating environment.
Spark Plug Replacement:
Intervals vary significantly by plug type (copper, platinum, iridium) and engine, often between 12,000 - 30,000 miles.
Timing Belt Replacement:
Crucial for OHC and Zetec engines. Typically 36,000 - 60,000 miles or 4-5 years. Interference engine design makes failure catastrophic.
Engine Oil:
Varies by engine, typically 10W-40 or 20W-50. Check manual for specific API/ACEA ratings and capacity (e.g., ~4.0 - 5.5 liters).
Coolant:
Ethylene glycol-based antifreeze, typically mixed 50/50 with distilled water. Specify Ford coolant type (e.g., Yellow/Orange concentrate).
Transmission Fluid Manual:
API GL-4 gear oil, viscosity grade like 75W-90 or 80W-90. Capacity varies.
Transmission Fluid Automatic:
Mercon/Type F or equivalent automatic transmission fluid (ATF). Check manual for specific type and capacity.
Brake Fluid:
DOT 3 or DOT 4 glycol-based brake fluid.
Rust And Corrosion:
Common on older models, especially wheel arches, sills, and rear strut tops. Check underbody thoroughly.
Suspension Wear:
Worn ball joints, tie rod ends, and bushes are common due to age and mileage. Rear trailing arm bushes can wear significantly.
Electrical Gremlins:
Can suffer from intermittent electrical faults, particularly related to grounding points, fuse boxes, and dashboard wiring.
Heater Matrix:
Can leak, causing interior dampness and loss of coolant. Replacement can be labor-intensive.
Timing Belt Failure:
Critical for OHC and Zetec engines. Regular replacement is essential to prevent catastrophic engine damage.
Exhaust System Corrosion:
Prone to rust, especially manifold and catalytic converter (if fitted).
