2.0L V6 (AJ20) - Entry Level Executive
Petrol
While idling in Park, listen closely for a rhythmic ticking or rattling from the engine bay, as the AJ20 V6 timing chain tensioners can sometimes show their age on high-mileage examples.
Check the gear changes by accelerating firmly onto a motorway; if the automatic transmission exhibits any flare or hesitation, it may indicate that the fluid is due for a change or that the valve body is feeling the effects of time.
During low-speed maneuvering, listen for any clunking or knocking noises from the front suspension, as the X-Type's bushings and control arms are common wear items on New Zealand's varied road surfaces.
Before turning the engine off, operate the air conditioning and heater controls through all vents; the blend door actuators occasionally develop a 'clicking' sound or fail to switch temperatures correctly.
Usually marks the window where suspension bushings and cooling system hoses have likely reached the end of their design life.
A common point where secondary ignition components, such as coil packs, may require testing or replacement to maintain smooth V6 performance.
Check the coolant reservoir for any signs of discolouration, as keeping the cooling system in top shape is key to longevity for the AJ20 engine.
Inspect the underside for any surface corrosion, paying particular attention to the rear subframe which can accumulate grit and moisture.
Confirm the history of the transmission fluid service; while often marketed as 'sealed for life', a refresh can significantly improve shift quality.
Verify that the battery is healthy and the terminals are clean, as these cars are quite sensitive to voltage fluctuations which can cause phantom electrical gremlins.
Check the condition of the brake lines and hoses, as the rubber can perish over time, affecting pedal feel.
Estimated repair costs if issues arise
If the car has its original radiator or water pump, it is worth keeping an eye on these. Future Budget Planning: You might eventually need to budget for a preventative replacement of the water pump and thermostat housing to ensure the engine stays cool.
The X-Type handles beautifully, but the control arms and sway bar links take a fair bit of abuse. Future Budget Planning: Depending on how the car feels over bumps, you might eventually need to budget for a suspension refresh to restore that 'Jaguar ride' quality.
The V6 engine uses individual coil packs which can fail as they age. Future Budget Planning: If you notice an occasional misfire or rough idle, it is common to replace these as a set to ensure smooth operation.
