Engine Variants:
Likely covers common gasoline and diesel engines for the Astra G generation (e.g., 1.4L, 1.6L, 1.8L, 2.0L gasoline; 1.7L, 2.0L diesel). Specific engine codes would typically be detailed within the manual.
Horsepower Range:
Varies by engine, typically from 60 hp to 140 hp for the specified years. Manual would provide exact figures for each variant.
Torque Range:
Varies by engine, typically from 95 Nm to 190 Nm. Manual would provide exact figures for each variant.
Fuel Delivery:
Electronic Multi-Point Fuel Injection (MPI) or Direct Injection (DI) depending on engine. Manual details specific systems.
Fuel Type:
Unleaded gasoline, Diesel
ECU:
Engine Control Unit (ECU) diagnostics and programming information included.
Oil Change:
Typically every 15,000 km or 1 year, whichever comes first. Specific intervals are detailed in the manual based on engine type and driving conditions.
Timing Belt Replacement:
Crucial for many Astra G engines. Typically recommended every 60,000-100,000 km or 4-6 years. Manual provides exact interval and procedure, including replacement of water pump and tensioners.
Engine Oil:
Viscosity typically 5W-30 or 5W-40, meeting API SJ/SL or ACEA A3/B3/B4 specifications. Manual specifies exact grade and capacity (e.g., 3.5-4.5 liters depending on engine).
Coolant:
G12 or G12+ pink/red ethylene glycol-based coolant. Manual specifies capacity and mixture ratio.
Brake Fluid:
DOT 4 brake fluid. Manual specifies replacement interval (e.g., every 2 years).
Transmission Fluid:
Manual specifies GL-4 or GL-5 gear oil for manual transmissions and Dexron III/VI for automatic transmissions. Capacity varies by transmission type.
Common Problems:
Potential issues include ignition coil failure, thermostat housing leaks, rear axle bearing wear, ABS sensor failures, and some electrical gremlins. The manual would offer diagnostic steps for these.
Rust:
Rust can be a concern on older vehicles, particularly around wheel arches and sills. Manual may offer advice on body preservation.
