2.4L (AJA) - Naturally aspirated diesel
Diesel
Listen carefully for heavy clunking or clicking during full-lock turns, as the CV joints on these T4s may show signs of wear given their age and typical loading history.
Observe the exhaust smoke upon a cold start; while a little diesel haze is common, persistent blue or heavy grey smoke might suggest the valve stem seals or rings are getting tired.
Test the gear linkage by moving through all gears while stationary and then on the move; a vague or 'sloppy' gear lever is a common trait in high-mileage T4s due to wear in the plastic bushings.
Check the cooling system performance by monitoring the temperature gauge during a longer hill climb; these naturally aspirated diesels work hard, and a cooling system that isn't tip-top can lead to issues under load.
Usually marks the period where original suspension components and rubber bushings begin to exhibit signs of fatigue.
A common point to verify the health of the alternator and starter motor, as well as the condition of the radiator hoses.
Entering the 'legacy' phase where consistent documentation of cooling system and fuel injection pump maintenance becomes the most vital indicator of future reliability.
Check the cambelt service history; this is the most critical item on the 2.4L AJA engine to ensure it has been changed within the manufacturer's recommended intervals.
Inspect the coolant reservoir for any signs of oil contamination or discoloration, which can indicate internal seal concerns.
Look underneath for signs of oil weeping from the engine or gearbox, keeping in mind that minor dampness is fairly common in vehicles of this vintage.
Test all electrical accessories, including the cabin fan speeds and rear wiper, as these switches can occasionally develop contact resistance over time.
Check the condition of the sliding door track and rollers to ensure smooth operation and proper seal closure against the weather.
Estimated repair costs if issues arise
Since the 2.4L AJA is an interference engine, if there isn't clear proof of a recent change, it is wise to budget for this immediately to avoid major engine repair costs. This job includes the belt, tensioners, and water pump.
Depending on the vehicle's past usage, specifically if it has been used for towing or city driving, you might eventually need to budget for a clutch replacement. It's often best practice to address the flywheel at the same time.
If the van feels a bit wallowy or hits bumps harshly, you might eventually need to budget for new shocks and ball joints to restore that classic T4 driving feel.
