🏷️ Basic Information Identification Make: Renault Model: R21 / Nevada Year: 1988 Codes Chassis Code: L48 (R21 Hatchback/Saloon), K48 (R21 Nevada/Estate) 👋 Introduction Market Position Market Segment: Mid-size family car and estate, positioned to compete with vehicles like the Ford Sierra, Opel/Vauxhall Cavalier, Peugeot 405, and Volkswagen Passat. Competitive Analysis Key Strengths: Spacious interior, comfortable ride, aerodynamic styling (especially the R21 saloon), practical Nevada estate variant, availability of efficient engines and advanced features for its time (like ABS and optional four-wheel drive on some variants). Key Features Unique Selling Points: The R21 was notable for its aerodynamic design and was one of the first mass-produced cars to feature a drag coefficient as low as 0.28. The Nevada offered exceptional practicality and cargo space. 📋 Manual Details Coverage Areas Models Covered: All R21 and Nevada variants (including all engine options, trim levels, and body styles) Repair Scope: A-Z comprehensive repairs Page Count Page Count: Likely 600-1000+ pages (typical for a complete dealer service manual of this era, exact count not provided but implied by scope) Manual Type Manual Type: Factory Service and Repair Manual (Official Dealer Workshop Manual) Language Language: English Format Format: Print (physical book) 📖 Manual Coverage Systems Covered Engine Systems: Engine mechanicals (cylinder head, block, pistons, crankshaft, camshafts), lubrication system, cooling system, fuel injection (Bosch LE2-Jetronic, K-Jetronic, multi-point injection depending on engine), ignition system, exhaust system, engine management (ECU diagnostics and testing).
