Safety Features Era:
While formal crash test ratings of the modern era were not common, these vehicles incorporated safety advancements for their time, such as a reinforced safety cell and crumple zones.
Braking System:
Front disc brakes and rear drum brakes. Later models and certain variants may have had four-wheel disc brakes. ABS was not a common feature for most of this production run.
Seatbelts:
Front seat belts were standard; rear seat belts were often optional or introduced later in the production run. The manual would detail their installation and maintenance.
Oil Change Interval:
Typically every 5,000 km or 3,000 miles, or as specified by the manual for specific engine types and oil used (e.g., using a high-quality mineral or semi-synthetic oil).
Tune Up Schedule:
Regular checks of spark plugs, ignition timing, carburetor/fuel injection adjustments, and air filter replacement at specified intervals (e.g., every 10,000-15,000 km).
Engine Oil:
Specific viscosity grades (e.g., SAE 10W-40, 15W-40, or 20W-50 depending on climate and engine condition) and API service classifications (e.g., SF, SG) are detailed in the manual. Diesel engines might require different specifications.
Coolant:
Typically a 50/50 mix of ethylene glycol antifreeze and distilled water. Manual specifies type and capacity.
Transmission Fluid:
Automatic transmissions require specific ATF fluids (e.g., Dexron II). Manual transmissions require gear oil (e.g., SAE 80W-90).
Common Wear Items:
Wear items like suspension bushings, ball joints, tie rod ends, exhaust systems, and rubber hoses are common points of maintenance and repair.
