2.8L (RD28E) - Diesel Efficiency version
Diesel
During your test drive, listen closely for any unusual clunking from the rear end; in cars of this age, it is common to consider that rear subframe bushes may be showing their miles.
Check the engine temperature gauge under varied driving conditions; it is worth noting that cooling systems on the RD28 platform appreciate a clean radiator and fresh coolant to stay happy.
Before turning the key, observe the glow plug indicator; if it seems to linger or behave inconsistently, it is helpful to keep in mind that the glow plug relay or plugs might eventually require a little professional attention.
Perform a cold start check; watch the exhaust for excessive smoke, as older diesel systems can sometimes indicate that injectors or fuel pump seals are reaching a stage where they might benefit from a service.
Usually marks the point where suspension bushings and engine mounts are worth a friendly inspection.
Often the time when cooling system components like the water pump and thermostat are due for a preventative refresh.
A common interval to check the integrity of the fuel lines and vacuum hoses to maintain optimal efficiency.
Treat your engine to high-quality diesel engine oil every 5,000 to 7,500km to keep those internal components clean.
Keep a close eye on the coolant condition; flushing it every two years helps prevent corrosion in the cooling system.
Regularly clean out the air filter to ensure your RD28 breathes easily and maintains its fuel efficiency.
Check the fuel filter during your standard service intervals to prevent any debris from impacting your fuel delivery.
Inspect your belts for any signs of cracking or fraying to ensure your alternator and power steering stay reliable.
Estimated repair costs if issues arise
If the vehicle begins to struggle with idling or cold starts in the future, it might be that the seals in the injection pump have hardened over time. Depending on the car's history, you might eventually need to budget for a specialized pump reseal or overhaul.
If the ride quality starts to feel a bit loose or 'floaty' on the open road, it is common to consider that shock absorbers and linkages may have reached the end of their service life. If this component needs attention in the future, the estimated cost in NZ is usually for a full set of quality shocks and bushings.
To keep the engine running at its best, it is wise to keep a small fund aside for cooling components. Depending on the car's history, you might eventually need to budget for a new radiator, water pump, and hoses to ensure long-term reliability.
