1.3L (2NZ-FE) - Standard Commercial Trim
Petrol
Listen for a rhythmic ticking or clicking sound during low-speed steering maneuvers, as worn CV joints are a common consideration for high-mileage commercial vehicles in New Zealand.
Opening the oil filler cap while the engine is running to check for excessive blow-by; while the 2NZ-FE engine is robust, internal wear can occur if previous oil change intervals were extended.
While driving at 80-100km/h on a motorway, feel for vibrations through the steering wheel or floor, which could indicate worn engine mounts or uneven tyre wear common in hard-working commercial trims.
Engaging the transmission from 'P' to 'R' and 'D' while stationary to note the delay or jolt any harsh clunks; this helps determine the health of the gearbox mounts and the torque converter.
Consider a full cooling system flush and check the condition of all rubber coolant hoses.
The alternator brushes and starter motor solenoid may benefit from an inspection or proactive servicing.
It is often wise to check the timing chain tensioner and look for any signs of chain stretch, which is rare but worth monitoring.
Stick to a strict 5,000km or 6-month oil change interval using high-quality 5W-30 or 10W-30 synthetic oil to keep the VVT-i system happy.
Keep an eye on the spark plugs; the 2NZ-FE engine performs best with fresh iridium or platinum plugs every 100,000km.
Ensure the transmission fluid is clean and red; if it looks dark or smells burnt, a drain-and-fill procedure can help preserve the transmission's life.
Inspect the rear leaf springs for any sagging or debris build-up, especially if the vehicle was previously used to carry heavy trade loads.
Regularly clean the Mass Air Flow (MAF) sensor with a specialized spray to maintain fuel efficiency and smooth idling.
Estimated repair costs if issues arise
Given the Probox's utilitarian suspension design, you might eventually need to budget for replacing lower control arm bushings to restore tight steering feel.
If you notice a slight coolant weep or a whining sound from the front of the engine, it is common to consider replacing the water pump before it fails completely.
If the cabin vibrations increase over time, these rubber mounts may have reached the end of their functional life and will require replacement to smooth out the ride.
