The Nissan Atlas, particularly the models from 1989 to 1991, represents a solid and reliable light truck that's seen its fair share of hard work in New Zealand. These earlier models, while not the flashiest, are known for their robustness and practicality. Let's delve into the technical aspects that Kiwi owners should be aware of.
Common issues with the 1989-1991 Nissan Atlas often revolve around age-related wear and tear. Diesel engines can suffer from injector issues, fuel pump problems, and turbocharger failures (if equipped). Petrol engines may experience carburetor (if applicable) or ignition system problems. Rust can be a significant issue, particularly in coastal areas. Check thoroughly around the cab, chassis, and cargo bed. Oil leaks from the engine and transmission are also common. Cooling system leaks (radiator, hoses) are also a potential weakness.
Key WOF (Warrant of Fitness) watchpoints for the 1989-1991 Nissan Atlas include: Rust (particularly around structural areas), worn or damaged suspension components (especially leaf springs and shock absorbers), brake performance (including condition of brake lines and cylinders), steering play, tyre condition (tread depth and sidewall integrity), lighting functionality (headlights, taillights, indicators), and exhaust leaks. Pay special attention to the condition of the load-carrying area and securing mechanisms. Ensure the windscreen is free from cracks or damage that could impair visibility.
The 1989-1991 Nissan Atlas were typically available with a range of diesel and petrol engines, each with its own strengths and weaknesses. Diesel variants were often favoured for their fuel efficiency and torque, making them ideal for hauling loads. Petrol engines, while less fuel-efficient, could offer a smoother and quieter ride.
The Atlas's chassis construction is relatively simple yet durable, designed to withstand the rigors of commercial use. Suspension components are generally robust, but age-related wear is a common factor. Regular inspection of the leaf springs (if equipped), shock absorbers, and suspension bushings is essential to maintain ride quality and handling. Brake systems, typically featuring front discs and rear drums, require regular maintenance to ensure optimal stopping power. The Atlas's manual transmissions are generally reliable, but clutch wear is inevitable with heavy use. Power steering systems, if equipped, should be checked for leaks and smooth operation.
