3.8L (6G75) MIVEC V6 - Exceed/VR-X
Petrol
Monitor the transmission shift quality; check for any flare or hesitation between 2nd and 3rd gear, as the Aisin 5-speed units in these models benefit from clean, fresh fluid.
Engage the Super Select II 4WD system while moving at slow speeds; ensure all dash indicators illuminate correctly without flashing, as vacuum solenoid issues can sometimes cause system confusion.
Listen closely during cold starts for a brief ticking noise, as the 6G75 engine's hydraulic lash adjusters can occasionally become noisy if the vehicle has experienced irregular oil change intervals.
Evaluate the steering rack for any play or weeping fluid, as the steering rack bushings and seals are components that often require attention as these vehicles accumulate higher mileage.
Usually marks the first major inspection of the intake plenum gasket and potential renewal of the spark plugs, which are buried deep under the intake manifold.
A common point where the cooling system components, such as the radiator and hoses, should be assessed for brittleness to prevent overheating.
Typically the time to verify the condition of the suspension bushings and CV boots, which may show signs of perishing due to age and NZ road conditions.
Prioritise regular engine oil changes using a high-quality synthetic 5W-30 or 10W-30 to keep those MIVEC components operating smoothly.
Keep a close eye on the transmission fluid colour and smell; it should ideally be a bright, translucent red.
Ensure the cooling system is flushed on schedule, as a healthy radiator is essential for the longevity of the 3.8L V6 engine.
Periodically inspect the underside for surface rust, particularly if the vehicle has spent time near the coast or in high-salt environments.
Verify that the timing belt (if applicable to your specific production batch) has been replaced according to the manufacturer's age-based recommendations, regardless of mileage.
Estimated repair costs if issues arise
Because the spark plugs are difficult to access on the 6G75 engine, labour costs can stack up. It is a good practice to budget for this during a major service interval.
If the transmission begins to show shifting irregularities, it is common to consider a professional diagnostic. Depending on the car's history, you might eventually need to budget for a valve body service.
After years of handling NZ's diverse road surfaces, the rubber bushings often lose their compliance. If this component needs attention in the future, the estimated cost in NZ covers a full kit and installation.
