2.5L (YD25DDTi) - Turbo Diesel economical trim
Diesel
While idling in 'Drive' with your foot on the brake, observe the steering wheel and dashboard for excessive vibration. | Note: The YD25DDTi engine uses hydraulic mounts which, at this age, often lose their dampening properties, leading to noticeable cabin vibration.
Check this by accelerating firmly from 40km/h to 80km/h on a slight incline. | Note: Pay attention to any hesitation or 'stuttering' in the turbo spool, as the vacuum-operated wastegate actuators can become sticky over time.
While parked, operate all power sliding doors and windows multiple times. | Note: The U30 generation features complex door electronics and cable assemblies that may show signs of fatigue after years of service.
Turn the climate control to 'Max Heat' and then 'Max Cold' while listening for clicking noises behind the glovebox. | Note: The blend door actuators are prone to becoming brittle, which may prevent the system from switching temperatures smoothly.
Consider a full cooling system refresh including a new thermostat and coolant flush.
The turbocharger bearings should be inspected for shaft play and the intercooler piping checked for oil leaks.
Monitor the timing chain tensioner and general engine noise patterns for signs of wear.
Prioritize oil changes every 7,500km to keep the YD25 engine's turbocharger lubricated correctly.
Regularly clear the sunroof and door drainage channels to prevent interior moisture buildup.
Inspect the CV joint boots for cracking during every warrant of fitness check.
Keep an eye on the transmission fluid color; a bright cherry red is what we want to see.
Verify the operation of the glow plug system before the cooler winter months arrive.
Estimated repair costs if issues arise
If the turbo begins to whistle excessively or lose boost, you might eventually need to budget for a professional overhaul or replacement.
As these are heavy MPVs, the front lower control arm bushings often take a beating. If this component needs attention in the future, it helps improve handling and tyre longevity.
Depending on the car's history, you might eventually need to budget for a professional clean or calibration of the fuel injectors to maintain fuel efficiency.
