3.5L VQ35DE V6 - Petrol FWD (350JM)
Petrol
While driving at low speeds, pay close attention to the CVT transmission for any shuddering or hesitation; in cars of this age, it is common to check if the belt-driven system is still providing smooth power delivery.
During your inspection, check the rear of the engine bay for any faint smells of burning oil; on the VQ35DE V6, the rear valve cover gasket is a component you might eventually need to budget for if leaks develop.
Listen carefully for clunking or knocking sounds when driving over speed bumps; given the weight of the 3.5L engine over the front axle, suspension bushes and struts are items that often require attention to maintain ride quality.
Cycle through all the climate control settings and check the central display functionality; it is worth ensuring the internal electronics and air-mixing actuators are operating correctly as these can be age-sensitive in early 2000s models.
This is a key time to verify if the long-life iridium spark plugs have been replaced, as the rear bank requires removing the intake manifold.
At this stage, it is wise to inspect the health of the cooling system, including the radiator and hoses, to ensure the V6 remains at an optimal temperature.
For high-mileage examples, focus on the condition of the engine mounts and the CVT fluid history to ensure continued refinement.
Verify the CVT fluid has been changed at regular intervals using the correct Nissan NS-2 specification.
Inspect the power steering high-pressure hose for any signs of seepage or dampness.
Ensure the cabin air filter is clean to maintain the effectiveness of the Teana's air purification system.
Check the condition of the serpentine belt for any cracking or signs of perishing.
Test the battery health, as the V6 starter motor and onboard electronics appreciate a strong, consistent voltage.
Estimated repair costs if issues arise
If the transmission begins to show signs of age, you might eventually need to budget for a professional flush or a refurbished unit to ensure smooth operation.
Depending on the car's history, you might eventually need to budget for this labour-intensive job, as the rear three cylinders are tucked away behind the manifold.
In cars of this age, it's common to consider replacing front control arms and struts to restore that signature Teana 'silk-carpet' ride quality.
If you notice vibrations while idling in 'Drive', you might eventually need to budget for new hydraulic engine mounts to keep the cabin quiet.
