The Renault 21 arrived in New Zealand during the late '80s, quickly establishing itself as a compelling contender in the mid-size saloon segment. Renowned for its smooth ride and distinctive French design, it offered Kiwi drivers a refreshing alternative to the conventional choices of Japanese and European vehicles. However, as with all vintage cars, age brings its own set of challenges that owners need to navigate carefully.
Rust (sills, wheel arches, suspension mounts), electrical system faults (wiring, relays), cooling system leaks (radiator, hoses), worn suspension components (bushes, ball joints), engine oil leaks. Overheating can be an issue if the radiator is blocked or the cooling system isn't properly maintained.
Check for rust, especially around structural areas. Ensure all lights are functioning correctly. Suspension components and steering rack must be in good condition with minimal play. Brakes need to be effective and balanced. Pay close attention to exhaust emissions - older engines may struggle to meet current standards.
The Renault 21 is equipped with a variety of engine options, ranging from fuel-efficient petrol engines to robust diesel variants. The handling and ride comfort remain commendable even today, while its generous interior space appeals to both families and individual drivers. Yet, potential issues such as rust—especially in the sills, wheel arches, and suspension mounting points—should be monitored closely. The electrical system has its quirks typical of cars from this era, so expect occasional faults in wiring and relays. Parts availability may sometimes pose a challenge, urging you to be proactive in sourcing replacements. Regular maintenance is crucial; checkups every 20,000 kilometers are advisable, particularly to address the regular wear and tear of suspension components and brakes.
Additionally, the cooling system requires attention around 150,000 kilometers, where key components like the water pump, thermostat, and radiator must be inspected or replaced. Addressing coolant leaks can prevent more costly repairs down the line. Brake components also need timely servicing; the front and rear brake systems should be overhauled at regular intervals to ensure optimal performance and safety. Investing in routine assessment of your Renault 21 not only preserves its classic charm but also guarantees a reliable driving experience for years to come.
