⚙️ Engine Specifications

Engine Types Covered:

Multiple 4-cylinder and 6-cylinder gasoline engines (specific displacements vary by model and year, e.g., 1.8L, 1.9L, 2.2L, 2.3L). Diesel variants may also be covered depending on specific model year implications.

Performance Data Availability:

Likely includes horsepower, torque, and power delivery curves for various engine options.

Fuel Delivery Systems:

Carbureted (early models), Bosch mechanical fuel injection (e.g., K-Jetronic on later models).

Engine Management:

Covered under 'Engine Control System' and 'Fuel Injection'.

🔧 Transmission

Transmission Types:

Likely includes 4-speed and 5-speed manual transmissions, and automatic transmissions (e.g., Hydrak or early automatic units).

Transmission Options:

Automatic transmission as an option over manual.

Transmission Service:

Covers repair, adjustment, and fluid service.

📐 Dimensions

Body Styles:

Sedan (likely), potentially Coupe and Convertible variants depending on specific 190/220 models.

Curb Weight Range Estimated:

Approximately 2,500 - 3,200 lbs (1135 - 1450 kg), varying significantly by engine and body style.

🛡️ Safety Features

Safety Ratings Era:

Pre-modern crash testing standards. Focus on inherent structural integrity and passive safety features of the era.

Active Safety Systems:

Basic braking systems (front discs, rear drums likely), steering.

Passive Safety Features:

Reinforced passenger cell, crumple zones (early implementation), seat belts.

💡 Technology Features

Infotainment Era Technology:

Basic AM/FM radio, possibly with cassette player on later models within the covered period. Manual will cover basic radio repair and antenna systems.

Driver Assistance Features:

None in the modern sense. Focus is on mechanical systems and driver control.

Connectivity Features:

N/A (vehicles of this era predated widespread electronic connectivity).

🔧 Maintenance

Typical Intervals:

Oil changes: 3,000-5,000 miles (4,800-8,000 km) or 6-12 months. Greasing: Periodic chassis lubrication. Ignition points/condenser: Service as needed. Spark plugs: Replacement at intervals (e.g., 15,000-30,000 miles).

Engine Oil:

Likely API SF or SG rated, SAE 10W-30 or 10W-40 depending on climate. (Manual will specify precise grade and API rating.)

Coolant:

Ethylene glycol based antifreeze, mixed 50/50 with distilled water. (Manual will specify type and capacity.)

Transmission Fluid Manual:

GL-4 gear oil, SAE 75W-90 or 80W-90. (Manual will specify.)

Transmission Fluid Automatic:

Dexron II or Mercon (early versions). (Manual will specify precise type and capacity.)

Brake Fluid:

DOT 3 or DOT 4. (Manual will specify.)

Common Wear Items:

Carburetor issues (if applicable), fuel pump reliability, ignition system components (points, condenser, coil), exhaust systems, rubber hoses and seals deterioration, suspension bushings, aging wiring harnesses, potential rust in older vehicles.

Engine Specific Concerns:

Early Mercedes engines were robust but required meticulous maintenance. Carburetor adjustments can be finicky. Fuel injection systems (like K-Jetronic) require specialized knowledge for diagnosis and repair.

📚 Vehicle History

Mercedes Benz Legacy:

Pioneering automotive manufacturer with a long history of engineering excellence and luxury vehicles.

W120 121 105 108 Evolution:

These models represent Mercedes-Benz's post-war entry into more compact and mid-size luxury segments, evolving from the ponton-era (W120/W121) to the more refined 'fintail' (W110/W111 - although not explicitly listed, the 220 could span into these) and the classic lines of the W108/W109 for some 220 variants.

Production Periods:

180/190: Mid-1950s to Mid-1960s. 220: Varied, with different chassis designations like W180, W128, W111, W108 covering the 1950s and 1960s.
