Ignition System: Distributor testing and adjustment, spark plug specifications, ignition timing procedures, and coil testing. Cooling System: Radiator inspection and service, thermostat replacement, coolant capacity and type specifications, and fan operation. Lubrication System: Oil pump operation, oil filter replacement, oil capacity and type, and lubrication points. Transmission: Manual and automatic transmission removal, installation, and in-car servicing. Gearbox internal repair, clutch service, and fluid specifications. Drivetrain: Driveshaft inspection, U-joint service, differential inspection and fluid specification. Brakes: Front disc and rear drum brake servicing, hydraulic system bleeding, brake pad/shoe replacement, caliper and wheel cylinder overhaul, and brake fluid type. Suspension: Front and rear suspension component inspection (control arms, ball joints, bushings), shock absorber replacement, and wheel alignment procedures and specifications. Steering: Steering box inspection and adjustment, tie rod end replacement, and power steering system service (if equipped). Electrical System: Complete wiring schematics, alternator and starter motor testing, battery specifications, lighting system troubleshooting, and fuse/relay identification. Body And Chassis: Body panel removal and installation, door and window mechanisms, sunroof operation and repair, and interior trim component identification. HVAC: Air conditioning system service, refrigerant capacities, and heater core inspection. Procedures Included Routine Maintenance: Factory recommended maintenance schedules, fluid changes (oil, coolant, transmission, differential), filter replacements (oil, air, fuel), and lubrication. Engine Repair: Detailed steps for engine disassembly, component inspection, seal replacement, reassembly, and initial startup. Transmission Repair: Clutch disc and pressure plate replacement, transmission gear synchronization, bearing replacement, and transmission fluid level checks. Brake System Repair: Brake rotor/drum resurfacing or replacement, brake caliper/wheel cylinder rebuilding, and brake line replacement. Suspension And Steering Repair: Ball joint replacement, tie rod end replacement, control arm bushing replacement, and power steering pump and rack service. Electrical Diagnostics: Troubleshooting electrical circuits using wiring diagrams, testing electrical components (switches, solenoids, sensors), and diagnosing starter/charging system issues. Troubleshooting: Diagnostic flowcharts and procedures for identifying the root cause of common drivability, starting, and electrical issues. Timing Belt Service: Procedures for chain removal and tightening (note: Rotary engines do not have timing belts in the conventional sense, this likely refers to accessory drive belts or internal chain components if applicable to specific early designs, or is a generic inclusion). If it pertains to the rotary's oil pump drive chain, detailed instructions would be present. Diagnostics: Computer diagnostic trouble trees and charts (may be rudimentary for the era, focusing on identifying fault codes or operational parameters). Front End Alignment: Detailed procedures and specifications for caster, camber, toe, and thrust angle adjustments. Technical Depth Depth: Comprehensive from basic maintenance to full engine and transmission rebuilds, including detailed electrical schematics and diagnostic procedures. 📊 Manual Specifications File Format Format: PDF Compatibility: Windows (XP, Vista, 7, etc.), Mac OS Software Requirements: Adobe Acrobat Reader Print Quality Printability: All pages are printable, with the option to enlarge images. Binding Type Binding Type: Digital Download (N/A for physical binding) Paper Type Paper Type: Digital (N/A for physical paper type) ⚙️ Engine Specifications Primary Engine Type: Rotary (Wankel) Displacement: 1.16 L (12A) - Effectively 1.16 liters of displacement, often referred to by its rotor housing diameter and width (12A). Performance Horsepower: Typically around 110-125 hp depending on model and emissions controls. Torque: Approximately 110-120 lb-ft. Fuel System Carburetion: Dual Hitachi downdraft carburetors (common), later models may have variations. Some performance variants might have aftermarket or dealer-installed Weber setups. Oil System Oil Type: Specific rotary engine oil (e.g., SAE 20W-50 or 10W-30, depending on climate and manufacturer recommendation). Critical to use oil suitable for rotary apex seals.
