The TOYOTA HIACE and REGIUS ACE are ubiquitous sights on New Zealand roads, prized for their reliability and versatility. Whether you're a tradesperson relying on it for your livelihood, a family needing space, or running a shuttle service, understanding the key maintenance points is crucial for keeping your HIACE/REGIUS ACE TD on the road.
Common issues in HIACE/REGIUS ACE TD models often include wear and tear on suspension components due to load-carrying, brake wear, oil leaks from seals and gaskets, rust in vulnerable areas, and timing belt issues around the recommended interval. Earlier models have also been known to experience injector pump failure. Auxiliary battery failure is also known to occur. Keeping an eye on sensor warning lights is also key.
When preparing your TOYOTA HIACE/REGIUS ACE TD for a WOF, pay close attention to the following:
• Brakes: Front brake pad thickness (must exceed 3mm) and overall brake performance are critical. Ensure there are no leaks in the brake system.
• Tyres: Check tire condition and tread depth.
• Lights: Ensure all lights are functioning correctly.
• Suspension: Inspect suspension components for excessive play and leaks. Pay particular attention to the condition of shock absorbers, leaf springs, and suspension bushes.
• Structural Integrity: Be aware of potential corrosion around the windscreen and chassis rails.
• Other: Sliding door operation and alignment will be checked. DPF system functionality (if applicable) will be assessed to ensure no warning lights are present. Excessive play in steering components will also be a WOF failure point.
Due to its popularity as a work and family vehicle the HIACE and REGIUS ACE have become an integral part of New Zealand's automotive landscape. Keeping your van well-maintained will ensure its longevity and reliability.
Engine & Drivetrain Considerations:
• Maintaining the timing belt is critical. Failure to replace it at the recommended interval (typically around 100,000 km) can lead to severe engine damage. Keep a record of your timing belt replacement and adhere to recommended intervals.
• Pay attention to air and fuel filters. Neglecting these can reduce engine performance and fuel economy. Regular replacement is advised.
• Injector pump failure, particularly on earlier models, is a known issue. Be alert for any signs of rough running or reduced power.
• Keep an eye on the alternator belt tensioner which tends to seize around 150,000km's
Suspension & Braking:
• The HIACE/REGIUS ACE, often used for heavy loads, experiences wear on suspension components. Regularly inspect suspension bushes, especially the front lower control arm bushes on the front and the rear leaf spring bushings, for wear and tear. Symptoms include clunking noises and poor handling. Addressing these issues promptly will maintain safe handling.
• Brake pad wear, particularly at the front, is common due to frequent use and heavy loads. Regularly check brake pad thickness and replace them as needed.
• Keep an eye on the shock absorbers as they also tend to experience wear and sagging leaf springs are also known to occur.
Other Areas to Watch:
• Rust in the rear wheel arches and sills is a common problem. Regular cleaning and rust prevention measures can help mitigate this.
• Sliding door rollers and cable wear affect smooth operation. Lubricate regularly and replace worn components.
• Front suspension lower ball joints are susceptible to wear, especially if neglected. Check regularly and replace as needed.
• Oil leaks often stem from worn axle and drive shaft oil seals. Address leaks promptly to prevent further damage. Also check the engine oil pan gasket.
• It is also worth considering monitoring the life and health of the auxiliary battery.
Proper maintenance and timely repairs will keep your TOYOTA HIACE/REGIUS ACE TD running smoothly and reliably for years to come.
