While driving, check the transmission's willingness to shift gears smoothly; the 4-speed automatics can sometimes show hesitation, so ensure there are no harsh 'clunks' when selecting Drive or Reverse.
Check this by turning the steering wheel to full lock in both directions while stationary; the steering boxes on these models can occasionally develop play or minor leaks as they age.
While driving, listen closely for any vibrations or 'whine' under acceleration; the prop-shaft center bearings are known to wear over time and may require inspection.
Check this by activating the 4WD system on a loose surface (like gravel); ensure the transfer case engages and disengages promptly without grinding noises.
Consider a full cooling system refresh including a new thermostat and radiator hoses.
Check the condition of the engine mounts, as the M104 engine produces significant torque which can lead to mount fatigue.
Inspect the alternator and starter motor brushes, as these are common service items at this stage.
Keep a close eye on the engine oil level between services, as these M104 engines appreciate regular fresh oil.
Check the condition of the vacuum lines under the bonnet, as aging rubber can lead to idling quirks.
Regularly inspect the underside of the vehicle for signs of surface rust, especially if the vehicle has seen beach use.
Ensure the cooling system is topped up with the correct specification coolant to protect the alloy head.
Keep the wheel alignment checked regularly to prevent uneven tyre wear, which can be accelerated by the weight of the vehicle.
Estimated repair costs if issues arise
Given the M104's design, it's worth monitoring for any external oil weeping. If this component needs attention in the future, the job involves removing the cylinder head and replacing seals to ensure long-term reliability.
Depending on the car's history, you might eventually need to budget for a transmission fluid and filter change to keep those gear shifts smooth and extend the life of the unit.
If this component needs attention in the future, you are essentially refreshing the ride quality. Replacing worn bushings ensures the steering feels planted and secure on our winding NZ roads.
