The Mitsubishi Sigma Base was a common sight on New Zealand roads in the early 1980s, offering reliable and affordable family transport. Regular maintenance and awareness of some common issues can help keep your Sigma running smoothly for years to come. This guide provides insights into Sigma ownership, focusing on what to watch out for and how to properly service your vehicle.
Owners of Mitsubishi Sigma Base models should be aware of a few common trouble spots. Rust, particularly in the rear wheel arches, is a frequent issue, as are problems associated with the automatic transmission at higher mileage, such as slipping between gears. Keeping regular checks of hoses under the hood can also provide alerts to when these items are deteriorating.
When taking your Mitsubishi Sigma Base for a Warrant of Fitness (WOF) inspection, be mindful of the following potential issues: rust around the windscreen and sills, which are common failure points, and brake hoses. Regular checks of your brake lines can help ensure your Sigma comfortably passes its WOF.
As a popular choice for Kiwi families in its prime, the Sigma provided practical and economical transportation. While it may not boast performance or cutting-edge technology, it presents a unique opportunity to engage in DIY maintenance while respecting its quirks and areas prone to wear.
Servicing Your Sigma:
The recommended service interval for the Mitsubishi Sigma Base is every 10,000 kilometers. Regular servicing is crucial for maintaining its reliability. This should include changing the engine oil and oil filter, as well as inspecting and replacing other fluids and filters as needed. Proper maintenance helps prevent costly repairs down the line.
Considering the age of these vehicles, more frequent inspections, especially of rubber components, are advisable. Keeping on top of maintenance needs will reduce the impact of age related wear and tear.
Known Weak Points:
Several areas require particular attention on the Sigma Base:
• Automatic Transmission: Automatic transmission failures can be a concern, especially in vehicles with higher mileage. Watch for any signs of slipping or erratic shifting which is a common indicator of needed attention.
• Rust: Rust is a common enemy of older vehicles, and the Sigma is no exception. Pay close attention to the rear wheel arches and around the windscreen and sills, as these are prone to corrosion. Preventative measures can significantly extend the life of these areas.
