⚙️ Engine Specifications

Engine Type:

Overhead Valve (OHV) V8

Displacement:

300 cubic inches (4.9 L) standard for the LeSabre series in 1964. Larger optional engines like the 325 cu in (5.3 L) and 401 cu in (6.6 L) Wildcat V8 might have been available or specified for certain 4400 configurations, though the manual's comprehensive coverage is key.

Horsepower:

The 300 cu in V8 typically produced around 210-225 horsepower with a two-barrel carburetor. Optional engines offered higher outputs (e.g., 401 Wildcat V8 producing 325-340 hp).

Torque:

Torque figures varied with engine and carburation, but were substantial for the era, contributing to the car's effortless cruising. The 300 cu in V8 likely produced around 305 lb-ft.

Carburetor:

Typically equipped with a Rochester 2-barrel carburetor. Four-barrel carburetors were common on larger engine options.

Fuel Type:

Regular Unleaded Gasoline (though leaded fuel was standard in 1964).

🔧 Transmission

Type:

Buick's Dynaflow automatic transmission (a 2-speed automatic with torque converter) was the hallmark of Buick luxury and smooth operation. A 3-speed manual transmission was likely available as a no-cost option, though less common.

Type:

3-speed manual transmission, potentially other automatic options depending on specific drivetrain packages.

Dynaflow Characteristics:

Known for its exceptionally smooth, gearless acceleration and quiet operation. It featured a variable-pitch torque converter for improved responsiveness.

📐 Dimensions

Wheelbase:

Approximately 119 inches (standard for Buick's B-body cars).

Length:

Around 206 inches.

Width:

Approximately 76 inches.

Height:

Around 54-55 inches (coupe models).

Curb Weight:

Typically in the range of 3,800 - 4,200 lbs, depending on engine and equipment.

🛡️ Safety Features

Crash Safety:

No formal crash test ratings exist for this era. Safety features were basic by modern standards.

Braking System:

Hydraulic drum brakes on all four wheels. Power assist brake systems were likely an option. The manual will detail drum brake adjustment and relining procedures.

Seat Belts:

Lap belts were likely standard in the front; shoulder belts and rear belts were optional or not available on all models. The manual may cover installation of aftermarket or factory-upgrade belts.

Steering Column:

Collapsible steering column was a nascent safety feature in this era. The manual would detail its function and replacement.

💡 Technology Features

Audio System:

AM radio with push-button tuning was standard. AM/FM radio and Wonderbar radio (seeking tuner) were common options. Speaker placement would be in the dash and potentially rear package tray.

Dashboard Controls:

Mechanical gauges (speedometer, fuel, temperature, oil pressure) and indicator lights. Control for lights, wipers, heater/defroster, and radio.

Cruise Control:

Speed-minder or 'Cruise-Master' cruise control was an available option on higher-trim Buicks and could be found on some LeSabre models. The manual would cover its operation and troubleshooting.

Power Steering:

Power steering was a widely available option and highly recommended due to the vehicle's size and weight. The manual details its hydraulic system.

Power Brakes:

Power assist for brakes was also a common and desirable option. The manual covers the vacuum booster system.

🔧 Maintenance

Oil Change Interval:

Typically every 3,000 to 4,000 miles or 6 months. The manual will specify the exact interval based on driving conditions.

Tune Up Interval:

Spark plugs, points, and condenser would typically be checked/replaced every 10,000 to 12,000 miles. Timing adjustments would also be part of tune-ups.

Transmission Fluid:

Dynaflow fluid changes were recommended at intervals of 25,000 to 30,000 miles. The manual will detail the correct procedure and fluid type.

Engine Oil:

API Service Classification MS (Motor Service) was standard. Viscosity grades like SAE 10W-30 or SAE 10W-40 were common, depending on ambient temperature. The manual will specify the exact SAE grade and API classification.

Coolant:

A mixture of ethylene glycol-based antifreeze and water, typically a 50/50 mix, would be recommended for freeze protection and corrosion inhibition. The manual will specify the type and capacity.

Transmission Fluid:

For Dynaflow, specific DEXRON fluids were not yet common; Type A Suffix A (TASA) transmission fluid was typically specified. The manual will confirm the exact specification.

Rear Axle Fluid:

Hypoid gear oil, typically SAE 90W, with limited-slip additive if equipped with a limited-slip differential (less common in base models).

Common Problems:

Rust on body panels (especially lower fenders, rocker panels, and quarter panels), carburetor wear and adjustment issues, ignition system maintenance (points, condenser), potential for oil leaks from gaskets and seals, U-joint wear in the driveshaft, and vacuum leak issues affecting engine performance. Drum brake adjustments can be frequent.

Dynaflow Quirks:

Dynaflow's relatively inefficient operation at low speeds and its tendency to overheat in heavy traffic or sustained steep inclines. The manual will cover maintenance to mitigate these issues.
