Cooling Capacity And Type:

Pressurized cooling system. Manual will specify coolant type (e.g., ethylene glycol-based) and system capacity. Thermostat operation and radiator service covered.

Engine Identification:

The manual will contain information on how to identify specific engine codes and their corresponding specifications.

🔧 Transmission

Transmission Type Standard:

For most full-size models (Electra, Wildcat, Riviera): Turbo-Hydramatic 400 (TH400) automatic transmission. For GS models, both automatic and manual transmissions may have been available.

Transmission Type Optional:

Some GS models might have offered a 3-speed or 4-speed manual transmission (e.g., Muncie). Manual will detail all available options.

Automatic Transmission Features:

Torque converter, planetary gear sets, hydraulic control system. Manual details internal components, valve body operation, and shift linkage adjustments.

Transmission Gear Ratios:

Specific gear ratios for available transmissions (automatic and manual) will be detailed within the manual, crucial for performance tuning or repair.

📐 Dimensions

Wheelbase And Length:

Wheelbases varied by model: Electra/Wildcat/Riviera typically had longer wheelbases (e.g., around 124-127 inches), while GS models (based on Skylark/Special platforms) had shorter wheelbases (e.g., around 112-116 inches). Manual provides exact dimensions for each model.

Wheelbase Variations:
