Detailed electrical wiring diagrams for all major circuits, facilitating fault diagnosis and repair.
Suspension:
Front independent suspension (MacPherson struts) and rear torsion beam or independent suspension, including shock absorbers, springs, and alignment.
Steering:
Manual and power steering systems, including steering column, rack and pinion, and tie rod ends.
Cooling System:
Radiator, coolant hoses, water pump, thermostat, and fan operation.
Fuel Injection Fuel System:
Fuel tank, fuel pump, fuel lines, fuel filter, and fuel injection systems (e.g., single-point injection or multi-point injection depending on engine).
Emission System:
Emission control systems, including exhaust gas recirculation (EGR), catalytic converter, and evaporative emission control (EEC).
Engine Control System:
Engine control unit (ECU) operation, sensors, and actuators for fuel injection and ignition timing.
Chassis Body:
Body construction, frame, doors, windows, interior trim, and exterior panels.
Restraint System:
Seat belts and any early forms of airbag systems if applicable to the 1991 model year.
Axle:
Front and rear axle components, including drive shafts and bearings.
General Maintenance:
Routine checks, fluid changes, filter replacements, and preventative maintenance tasks.
Troubleshooting:
Systematic diagnostic procedures for common and uncommon problems, symptom analysis, and fault code interpretation.
Disassembly Reassembly:
Step-by-step instructions for removing, overhauling, and reinstalling major vehicle components.
Refurbish Renovate:
Guidance on restoring worn or damaged components to proper working order.
Periodic Lubrication:
Specific lubrication points and recommended lubricant types and intervals.
Depth Of Coverage:
Full workshop level, covering everything from basic maintenance to complete engine and transmission rebuilds, complex diagnostics, and bodywork repairs.
Oil Change Interval:
Typically every 6,000 - 10,000 miles (10,000 - 15,000 km) or annually, depending on driving conditions. Consult manual for precise intervals.
Spark Plug Replacement:
Intervals varied by spark plug type (copper, platinum); typically 20,000 - 30,000 miles for copper, longer for platinum. Check manual.
Timing Belt Replacement:
Crucial for CVH and Zetec engines. Intervals often around 60,000 miles (100,000 km). Failure can cause catastrophic engine damage. Manual is essential.
Engine Oil Specification:
Likely API SF/SG or equivalent. Viscosity grade would typically be 5W-30, 10W-40, or 15W-40 depending on ambient temperature. Manual will specify exact grades.
Coolant Specification:
Ethylene glycol-based antifreeze, typically a 50/50 mix with distilled water. Manual specifies concentration and type.
Brake Fluid Specification:
DOT 3 or DOT 4 hydraulic brake fluid. Manual specifies exact type and replacement interval.
Common Wear Items:
Exhaust system corrosion, front suspension wear (bushings, ball joints), clutch wear, and potential electrical gremlins due to age.
Engine Specific Concerns:
CVH engines can be prone to oil leaks and timing belt issues if not maintained. Zetec engines are generally more robust.
