How Reliable Is A Daihatsu Hijet?
When it comes to compact utility vehicles, the Daihatsu Hijet stands out as a reliable kei truck that has built a strong reputation for durability, efficiency, and practicality. Whether you're considering a Daihatsu Hijet for work, off-road adventures, or daily use, understanding its reliability is key before making a purchase. In this guide, we’ll explore the Daihatsu Hijet’s reliability, common issues, maintenance needs, and why it remains a top choice for mini truck enthusiasts.
What Makes the Daihatsu Hijet a Reliable Vehicle?
The Daihatsu Hijet has been a staple in Japan’s kei truck segment for decades, offering a fuel-efficient, compact, and low-maintenance solution for businesses and personal use. Here are some factors that contribute to its reputation for reliability:
1. Proven Engine Performance
The Daihatsu Hijet is powered by a small but efficient three-cylinder engine, typically ranging between 550cc and 660cc depending on the model year. Despite its small size, the engine is designed for longevity, with many owners reporting hundreds of thousands of kilometres without major mechanical failures when properly maintained.
Key Features of the Daihatsu Hijet Engine:
- Fuel-efficient with average consumption of 5-6 litres per 100 km
- Chain-driven timing system (in newer models) reduces the need for frequent belt replacements
- Reliable fuel injection system for smoother performance
2. Simple and Robust Mechanical Design
Unlike modern vehicles that rely on complex electronic components, the Daihatsu Hijet maintains a straightforward mechanical layout, making it easy to repair and maintain. Its simple design reduces the likelihood of electrical failures, making it an excellent choice for buyers looking for a dependable mini truck.
3. Strong Build Quality and Durability
The Hijet’s chassis and body are built with a focus on durability. Designed for commercial use, many business owners and farmers rely on the Hijet for heavy-duty hauling and off-road conditions. The frame is reinforced to handle tough terrains, and the suspension system is tuned to absorb impact, ensuring a smooth and stable drive.
4. Availability of Spare Parts and Aftermarket Support
One of the biggest concerns when buying an imported or specialty vehicle is the availability of spare parts and accessories. Fortunately, Daihatsu Hijet parts are widely available through aftermarket suppliers, making repairs and maintenance cost-effective. At Davey Motor Group’s spare parts store, you’ll find genuine and high-quality aftermarket parts to keep your Hijet running smoothly.
Common Issues with the Daihatsu Hijet and How to Prevent Them
While the Daihatsu Hijet is known for its reliability, no vehicle is completely immune to wear and tear. Here are some common issues and how to prevent them:
1. Cooling System Problems
The Hijet’s radiator and cooling system can become clogged over time, leading to overheating issues.
Prevention:
- Regularly flush and refill the coolant every 20,000 km
- Check for radiator leaks or blockages
- Ensure the thermostat and water pump are functioning properly
2. Transmission Wear
Many Daihatsu Hijet models come with manual and automatic transmission options. In older models, gear grinding or transmission hesitation may develop over time.
Prevention:
- Use high-quality transmission fluid and replace it at recommended intervals
- If driving a manual, avoid excessive clutch riding or aggressive shifting
- Regularly inspect the clutch and gear synchronizers
3. Rust and Corrosion
Because the Hijet is often used in rural and coastal environments, exposure to mud, moisture, and road salt can lead to rust formation on the chassis and undercarriage.
Prevention:
- Apply rust-proofing treatment to vulnerable areas
- Regularly wash the undercarriage to remove debris and salt buildup
- Store the vehicle in a dry, covered area when not in use
4. Electrical Issues
Like many older vehicles, the Daihatsu Hijet may experience minor electrical faults, particularly in older wiring harnesses and connectors.
Prevention:
- Check and clean battery terminals and wiring
- Replace old fuses and relays as needed
- Upgrade to LED lighting for better efficiency and reduced strain on the electrical system
How to Maintain a Daihatsu Hijet for Long-Term Reliability
Proper maintenance is the key to keeping your Hijet running smoothly for years. Here’s a routine maintenance checklist:
Regular Maintenance Schedule
✅ Oil Changes: Every 5,000–7,500 km using high-quality synthetic oil ✅ Air Filter Replacement: Every 15,000 km to maintain optimal fuel efficiency ✅ Brake Inspections: Every 10,000 km to ensure safe stopping power ✅ Suspension and Steering Checks: Annually, especially if used on rough terrain ✅ Timing Chain/Belt Inspection: As per manufacturer guidelines ✅ Tyre Rotations & Pressure Checks: Every 5,000 km for even wear and fuel economy
By following these steps, your Daihatsu Hijet can easily last for decades with minimal major repairs.
