⚙️ Engine Specifications

Engine Displacement Range:

1.7L (1700cc) to 2.3L (2300cc) - covering B17, B19, B21, B23 variants.

Engine Type:

Inline-four cylinder, typically naturally aspirated gasoline, with potential for turbocharger variants across different models.

Horsepower Range:

Varies significantly by displacement and specific engine variant, typically ranging from approximately 80 HP to 130+ HP in naturally aspirated form.

Torque Range:

Varies by displacement and tuning, typically in the range of 100 lb-ft to 160 lb-ft.

Fuel Delivery:

Carbureted (e.g., Zenith Stromberg, SU) and early Bosch K-Jetronic fuel injection systems, depending on the specific engine variant and model year.

🔧 Transmission

Common Transmission Types:

Manual transmissions (e.g., M45, M46, M47) and automatic transmissions (e.g., BW35, AW70/71) were common.

Overdrive Options:

Overdrive gears were often available on manual transmissions (M46 designation often indicates an overdrive 4th or 5th gear).

Transmission Fluid Spec:

Specific fluid types (e.g., Dexron II/III for automatics, GL-4 gear oil for manuals) would be detailed in the manual.

📐 Dimensions

Applicable Vehicle Types:

Primarily covers engines used in Volvo models such as the 240, 260, 740, 760 series, and potentially earlier 300 series models, as well as some related marques depending on engine sharing.

Engine Weight Approximate:

Approximate dry weight for these inline-four engines typically falls in the range of 150-200 kg (330-440 lbs), depending on ancillaries.

🛡️ Safety Features

Vehicle Safety Context:

While this manual focuses on the engine, it supports vehicles that have a history of good safety ratings for their respective eras, a Volvo hallmark.

Engine Management Safety:

Information on engine control and ignition systems contributes to safe operation.

Component Safety Details:

Properly maintained and repaired engine components are critical for overall vehicle safety.

💡 Technology Features

Infotainment Context:

These engines were fitted in vehicles from an era where infotainment was rudimentary or non-existent, primarily focused on basic radio and cassette players.

Driver Assistance Features:

Driver assistance features were minimal to non-existent during the primary production period of these engines.

Connectivity Features:

No advanced connectivity features like Bluetooth or USB were integrated.

🔧 Maintenance

Oil Change Interval Typical:

Typically every 5,000 - 7,500 miles (8,000 - 12,000 km) or 6-12 months, depending on driving conditions and oil type.

Timing Belt Interval:

Timing belt replacement intervals are critical and would be specified by model year and engine variant, often around 60,000 - 90,000 miles (100,000 - 150,000 km).

Engine Oil Viscosity:

Commonly specified viscosities include 10W-30 and 10W-40. The manual will provide precise recommendations based on ambient temperature.

Coolant Type:

Ethylene glycol-based antifreeze with corrosion inhibitors. Specific Volvo-recommended mixtures or equivalent would be detailed.

Brake Fluid Spec:

DOT 3 or DOT 4 brake fluid.

Common Engine Wear Points:

Oil leaks (valve cover gasket, rear main seal), cooling system component degradation (radiator, hoses), timing belt wear, and fuel system component aging (injectors, pumps in fuel-injected models).

Electrical Component Reliability:

Older wiring harnesses and ignition components can be prone to degradation, requiring careful inspection and potential replacement.

📚 Vehicle History

Volvo Engine Philosophy:

Volvo is renowned for building durable, reliable, and safe vehicles, and these B-series engines were central to that reputation during their production era.

Engine Family Progression:

The B17-B23 family represents Volvo's successful development of robust, overhead camshaft (OHC) inline-four engines, evolving over time with increased displacement and improved technology (e.g., fuel injection).

Production Era:

These engines were produced from the late 1970s through the 1980s and into the early 1990s in various forms.

🏆 Awards & Recognition

Brand Reputation For Durability:
