2.8L 4M40 Turbo Diesel - 4WD
Diesel
Listen closely to the cooling system during a long drive; ensure the temperature gauge stays steady, as these 4M40 engines can be sensitive to cooling system fatigue over time.
Shift through all 4WD modes on a gravel surface; check that the Super Select system engages and disengages smoothly, as lack of use can sometimes make the linkages feel a bit stiff.
Inspect the underside for signs of corrosion or persistent oil dampness, particularly around the rear axle and chassis rails, which is common in older 4WD vehicles used in coastal environments.
Observe the exhaust smoke upon cold start and under heavy acceleration; a small amount of haze is normal, but excessive blue or thick black smoke suggests it's worth a more detailed look at the turbo or fuel system.
Usually the time to ensure the auxiliary drive belts and thermostat have been refreshed.
A common point to review the suspension bushings and shocks to maintain that classic Delica ride quality.
Consider having the diesel pump and injectors professionally inspected if they haven't been touched in a long while.
Prioritise regular engine oil and filter changes every 5,000km to keep the 4M40 turbo happy.
Flush the coolant system periodically, as clean coolant is the best insurance for the cylinder head.
Regularly lubricate the chassis and driveshaft grease nipples to keep the 4WD components operating quietly.
Keep an eye on the air filter, especially if you enjoy exploring dusty New Zealand tracks.
Check the transmission fluid condition regularly; fresh fluid ensures smooth gear shifts.
Estimated repair costs if issues arise
Because these engines are robust but work hard, it's wise to plan for potential cooling system updates to keep temperatures in check. If this component needs attention in the future, the estimated cost in NZ is reflective of a high-quality head replacement and cooling overhaul.
After many years of Kiwi road use, the rubber components in the suspension may begin to show their age. Depending on the car's history, you might eventually need to budget for a complete bushing refresh to restore the handling.
The 4M40 turbo is generally reliable, but it is a wearable part. If performance feels a bit sluggish over time, budgeting for a service or replacement of the turbo unit will ensure you have plenty of power for those steep hill climbs.
