2.5L (RB25DE) - NEO Straight-Six
Petrol
While driving at low speeds, gently turn the steering wheel lock-to-lock to listen for any clicking or whining, as the C35 power steering pump can show its age on higher-mileage examples.
Check this by shifting into reverse and then drive while parked; a significant clunk or hesitation could indicate that the drivetrain mounts or the automatic transmission's health may require a professional inspection.
Before starting the engine, look under the chassis for any signs of wet patches, as the RB25 series engines can occasionally develop minor oil leaks from the cam covers or front main seal.
During the test drive, monitor the temperature gauge closely; the cooling systems in these vehicles are now quite aged, so ensure the needle remains steady and doesn't creep upward during idle.
Usually marks the point where suspension bushings and ball joints may start to show signs of perishing due to age and NZ road conditions.
Often the stage where ancillary engine components, such as the alternator and starter motor, might reach the end of their design life.
A period where thorough inspection of the cooling system components, like the radiator and water pump, is highly recommended to maintain reliability.
Prioritize a fresh engine oil and filter change using a high-quality synthetic oil to keep the NEO straight-six internals happy.
Inspect the timing belt history, as this is a crucial item to ensure remains within its service interval for peace of mind.
Flush the transmission fluid if the service history is unclear, as this can help maintain smooth gear shifts.
Check the condition of the spark plugs and coil packs, as the RB25 NEO can be sensitive to ignition system health.
Keep an eye on the coolant condition and consider a full system flush if the fluid appears discolored.
Estimated repair costs if issues arise
If the car develops a misfire under load, the factory coil packs may eventually need replacing. It is common to upgrade these to modern, more reliable aftermarket units.
Given the age of these vehicles, you might eventually need to budget for new shocks and control arm bushings to restore that classic smooth Laurel ride quality.
To protect your engine long-term, it's wise to consider that you might need to budget for a new radiator and hoses if the current ones appear brittle or original.
