Maintenance
|
|
Service Intervals
|
|
Oil Change Interval:
|
Typically 3,000-5,000 miles or 3-6 months (refer to manual for exact OEM recommendation based on driving conditions)
|
|
Transmission Fluid Change Interval:
|
Typically every 30,000-50,000 miles (refer to manual for exact recommendation)
|
|
Spark Plug Replacement:
|
Refer to manual, often around 30,000 miles for standard plugs, potentially longer for platinum/iridium if available for that era.
|
|
Fluid Specifications
|
|
Engine Oil Specification:
|
API Service SG or SH, SAE 10W-30 or 5W-30 (refer to manual for specific viscosity based on ambient temperature)
|
|
Coolant Specification:
|
Ethylene Glycol based antifreeze, typically a 50/50 mix with distilled water. Specific type may vary (e.g., traditional green or early orange).
|
|
Brake Fluid Specification:
|
DOT 3 Hydraulic Brake Fluid
|
|
Known Issues
|
|
Common Wear Items:
|
Alternator, water pump, starter motor, fuel pump (TBI systems), exhaust system components, suspension bushings, brake wear items.
|
|
Electrical Issues:
|
Wiring harness degradation, interior electrical component failures (window motors, radio, HVAC controls) due to age.
|
|
Engine Specifics:
|
TBI systems can be sensitive to fuel pressure and injector clogging. Early carburetors require periodic adjustment and cleaning.
