Binding Type Binding: N/A (Digital Access) Paper Type Paper Type: N/A (Digital Access) ⚙️ Engine Specifications Primary Engine Engine Type: Inline 4-Cylinder (I4) Engine Code: Identified by VIN and specific engine block markings, typically '1.9L' DOHC or SOHC variants existed. Displacement: 1.9 Liters (1898 cc) Performance Horsepower Range: Approximately 105-124 hp depending on SOHC vs. DOHC and specific tuning. Torque Range: Approximately 110-120 lb-ft depending on SOHC vs. DOHC. Fuel System Fuel Delivery: Multi-port Fuel Injection (MPI) Fuel Type: Unleaded Gasoline (87 octane recommended, though higher may be specified for DOHC variants) 🔧 Transmission Standard Transmission Type: 5-Speed Manual Transmission (Getrag F23 or similar GM derivative) Optional Transmission Type: 4-Speed Automatic Transmission (GM 4T40-E or similar) Features Drivetrain: Front-Wheel Drive (FWD) 📐 Dimensions Exterior Body Style: 2-Door Coupe Weights Curb Weight Approx: 2600 - 2800 lbs (depending on transmission and options) 🛡️ Safety Features Ratings NHTSA Front Impact: While specific official NHTSA ratings for 1994 models are difficult to find retroactively, the SC1 generally performed averagely for its era. The composite body panels offered some energy absorption. Active Features ABS: Anti-lock Braking System (ABS) often optional or standard on higher trims. Passive Features Airbags: Driver's side airbag standard. Body Construction: Advanced Composite Body Panels on a Steel Space Frame 💡 Technology Features Infotainment Audio System: Standard AM/FM radio, optional cassette player or CD player. Speaker configurations varied by trim. Driver Assistance Cruise Control: Cruise control was a common option. Connectivity OBD Standard: OBD-I (On-Board Diagnostics, First Generation). The manual would cover accessing and interpreting diagnostic codes for this standard. 🔧 Maintenance Service Intervals Oil Change Interval: Typically every 3,000 to 7,500 miles or 6 to 12 months, depending on driving conditions and oil type used (refer to manual for precise recommendation). Engine Coolant Interval: Initial change at 5 years or 100,000 miles, then every 2 years or 30,000 miles thereafter (using appropriate coolant). Timing Belt Replacement: If equipped with a DOHC engine, timing belt replacement is critical, typically around 60,000-100,000 miles. SOHC engines may have a timing chain. **Crucial to verify engine type for this interval.** Fluid Specifications Engine Oil Viscosity: Typically SAE 5W-30. Consult manual for specific engine and temperature range. Coolant Type: GM P/N 12346290 (Orange/Dex-Cool type for later models) or equivalent. Manual will specify the correct type for the 1994 model (likely traditional green ethylene glycol). Transmission Fluid Type Auto: GM DEXRON-III (or equivalent) Transmission Fluid Type Manual: GL-4 Gear Oil, SAE 75W-90 Known Issues Oil Consumption: Some Saturn engines, particularly higher mileage ones, can exhibit increased oil consumption due to worn piston rings or valve seals. Alternator Failure: Alternators can be a common failure point on these models. Rear Main Seal Leaks: Rear main engine oil seal leaks can occur. Power Steering Pump: Leaky power steering pumps or hoses are not uncommon. Suspension Wear: Worn control arm bushings, ball joints, and tie rod ends are typical wear items on any vehicle of this age. 📚 Vehicle History Brand Heritage...
