3.0L VQ30DD - 300GT
Petrol
Listen carefully for any rattle or hesitation during cold starts, as the VQ30DD direct injection system can sometimes show signs of wear in the high-pressure fuel pump assembly.
Observe the dashboard for any flickering or dimming warning lights, as older V35 electrical systems may occasionally encounter minor grounding or sensor communication quirks.
While driving at low speeds, gently turn the steering wheel to check for any 'clunking' noises, as front suspension bushings and control arms are common items that may eventually reach the end of their service life.
Check the transmission shifting by accelerating steadily; look for smooth transitions rather than 'hunting' for gears, as the 5-speed automatic requires clean, healthy fluid to perform at its best over time.
Consider a full cooling system flush and inspection of all rubber hoses.
A good time to inspect the alternator and starter motor for signs of aging.
Consider assessing the health of the suspension dampers and engine mounts for optimal ride comfort.
Keep an eye on the brake fluid condition to ensure responsive and consistent stopping power.
Periodically check the tire pressures and alignment, as the V35 setup can be sensitive to uneven wear.
Ensure the engine oil is clear and regularly changed every 5,000-8,000km to keep the VQ engine internals happy.
Check that the coolant is clean and bright green, as maintaining thermal efficiency is key for these V6 units.
Inspect the cabin air filter regularly to keep the air quality fresh for you and your passengers.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ reflects the specialized nature of the direct injection system used on the 300GT.
Depending on the car's history and road conditions, you might eventually need to budget for a refresh of the front-end bushings to restore that crisp handling feel.
While reliable, a professional transmission fluid flush is a great way to protect your investment. If you decide to do this, budget for high-quality synthetic fluid.
