The Mitsubishi Diamante and Magna, particularly those converted to LPG, were once a popular choice for New Zealand families seeking comfortable and affordable transportation. Many of these vehicles are now high-mileage examples, making regular maintenance and careful attention to potential issues crucial for ensuring their longevity and reliability. This guide provides valuable insights into keeping your Diamante/Magna LPG running smoothly.
Owners of Mitsubishi Diamante/Magna LPG vehicles should be aware of a few common problems that may arise with age and mileage:
• Oil Leaks: The Ecotec V6 engine found in many Diamante/Magna models is known to be prone to oil leaks as it ages. Regularly inspect for any signs of leakage and address them promptly to prevent more serious problems.
• LPG System Failures: LPG systems can experience component failures over time. Watch for issues such as difficulty starting, poor fuel economy, or unusual smells. Seek professional diagnosis and repair if you encounter any of these symptoms.
These issues often become apparent between 150,000 and 250,000 kilometers. Careful preventative maintenance can help mitigate these risks.
When taking your Mitsubishi Diamante/Magna LPG for a Warrant of Fitness (WOF) inspection in New Zealand, be particularly mindful of the following watch points:
• LPG System Compliance: Ensure that your LPG system is compliant with all relevant safety standards and has undergone the required testing.
• Rear Suspension Bushes: The rear suspension bushes are a common area of concern and are frequently checked during WOF inspections. Worn or damaged bushes can lead to handling problems and may result in a failed WOF.
Owning a Mitsubishi Diamante or Magna LPG presents a few unique considerations for New Zealand owners.
Maintenance Matters
Regular maintenance is essential for any vehicle, and the Diamante/Magna LPG is no exception. Pay particular attention to the following:
• Timing Belt Replacement: Adhere to the scheduled replacement interval for the timing belt to prevent potentially catastrophic engine damage. Ensure you check condition of your timing belt idler at the same time
• Fluid Checks: Regularly inspect and top-up or replace fluids such as automatic transmission fluid and power steering fluid as needed.
• Wiper Blades: Maintain clear visibility by replacing wiper blades (front and rear) when streaking or degradation occurs. Consider front wiper packs or rear wiper refills for a cost-effective solution.
• Thermostat Condition: A functioning thermostat is important to keep engine temps optimal
• Wheel Alignment: Using a camber bolt kit on the front of the car can help keep wheel alignment spot on if you are noticing inner tyre wear.
LPG System Considerations
LPG systems require specialized maintenance. Ensure you adhere to the manufacturer's recommended service schedule and address any performance issues promptly.
Suspension System Checks
Inspect your suspension components for serviceability. Suspension bushes, especially in the rear control arm (lower), are a common wear item on these vehicles and greatly affect road handling and safety.
