Engine Specifications
|
|
Primary Engine
|
|
Engine Options 1992:
|
Likely include 1.7L Twin Cam, 2.0L Twin Spark (16-valve), and potentially a 2.5L V6 (as found in some later 155 variants, though less common for early 1992 models).
|
|
Performance
|
|
Horsepower Range Approx:
|
115 hp (1.7L) to 150 hp (2.0L Twin Spark), potentially higher for V6.
|
|
Torque Range Approx:
|
140 Nm (1.7L) to 185 Nm (2.0L Twin Spark).
|
|
Fuel System
|
|
Fuel Delivery:
|
Electronic Fuel Injection (EFI) across all variants.
|
|
Engine Layout
|
|
Configuration:
|
Inline-4 (Twin Spark) and V6 (Busso V6)
|
|
Valve Train:
|
DOHC (Double Overhead Camshaft) for Twin Spark engines, often with 2 valves per cylinder for 8V and 4 valves per cylinder for 16V versions.
|
|
Engine Codes
|
|
Twin Spark Codes:
|
Likely 8V and 16V Twin Spark variants, e.g., AR67201 (1.7L), AR67203 (2.0L 8V), AR67204 (2.0L 16V).
|
|
Maintenance
|
|
Service Intervals
|
|
Oil Change Interval:
|
Typically every 10,000 km or 12 months (whichever comes first), dependent on oil quality and driving conditions.
|
|
Timing Belt Replacement:
|
Crucial for Twin Spark engines. Interval typically around 60,000-80,000 km or 4-5 years. Failure can cause catastrophic engine damage.
|
|
Fluid Specifications
|
|
Engine Oil Viscosity:
|
Refer to manual, typically 10W-40 or 15W-50 semi-synthetic or fully synthetic depending on engine type and climate.
|
|
Coolant Type:
|
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Specific color/type as per manual.
|
|
Brake Fluid Type:
|
DOT 3 or DOT 4.
|
|
Transmission Fluid Type Manual:
|
Refer to manual, typically a high-quality manual transmission fluid (e.g., SAE 75W-90 GL-4 or GL-5).
|
|
Transmission Fluid Type Automatic:
|
Refer to manual, typically Dexron II or equivalent.
|
|
Known Issues
|
|
Common Problems 155:
|
Rust ingress (especially around wheel arches, sills, and door bottoms), aging electrical connectors and wiring, potential issues with the Twin Spark ignition system (spark plugs, ignition coils), suspension wear (bushings, ball joints), and the need for regular timing belt maintenance.
|
|
Electrical Gremlins:
|
Common issues include deteriorating wiring insulation, faulty door lock actuators, and intermittent problems with dashboard warning lights due to age and vibration.
