2.8L CRD Diesel
Diesel
Check this by looking at the cooling system: Observe the temperature gauge during a long test drive to ensure it doesn't fluctuate, as these diesel units rely on a healthy cooling system to prevent head gasket stress.
While driving in low-speed manoeuvres: Listen for any clunking or knocking noises from the front end, as the control arm bushings and ball joints are known to wear out on these heavier diesel models.
Inspect this by engaging the 4WD system: Find a loose surface and shift into low range to ensure the transfer case engages smoothly without binding or unusual metallic grinding.
Test this by accelerating firmly on an open road: Watch for any hesitations or excessive black smoke, which may suggest the injectors or the mass air flow sensor are becoming fatigued due to age.
Common interval for timing belt replacement; verify if this service has been performed recently to avoid potential engine damage.
Suspension components like shocks and steering rack bushings often require inspection or replacement to maintain steering precision.
The turbocharger internals may show signs of wear, making it a good time to check for oil leaks and shaft play.
Keep a close eye on the transmission fluid level and color; these gearboxes perform best with fresh fluid at regular intervals.
Ensure the oil filter is replaced every 10,000km using high-quality synthetic oil to keep the turbocharger lubricated.
Regularly clean the EGR valve to prevent carbon buildup, which helps maintain fuel efficiency and engine responsiveness.
Check all rubber cooling hoses for signs of brittleness or swelling, as these are reaching an age where replacement is good practice.
Keep the battery terminals clean and tight, as modern electronics in the KJ are quite sensitive to fluctuating voltages.
Estimated repair costs if issues arise
Since this is a critical maintenance item for the 2.8L engine, you should consider if it has been done recently. If not, planning for this service will help protect your engine's longevity.
Diesel injectors can eventually lose their spray pattern, leading to poor fuel economy. It is wise to eventually budget for professional testing or refurbishment.
Given the weight of the diesel engine, the front suspension components work hard. Depending on the car's history, you might eventually need to budget for new control arms or shocks.
