Brand New D4HA 2.0L CRDi Turbo Diesel Engine for Hyundai ix35 2010-2015

About this engine

If your Hyundai ix35 runs the D4HA 2.0L CRDi turbo diesel, this listing is for a brand-new replacement engine built to OEM fitment specification, with internals upgraded where the engine works its parts hardest. It suits ix35 models sold between 2010 and 2015 and is supplied as a complete long engine, hot and cold tested before dispatch.

The ix35 gets used hard. Owners lean on the diesel for the daily commute, gravel-road running and hauling a box trailer or small camper on weekends, and the engine cops the load every time. When compression drops, a bearing lets go or the bottom end is worn past sensible repair, a new engine is often more economical than rebuilding the old one.

Before anything ships, we check your VIN against the engine at no charge, so you know it suits your exact build. Freight is free anywhere in Australia, and every engine carries a 12-month or 50,000 km parts warranty.

The R-series D4HA and its low-down pull

The D4HA is the 2.0-litre member of Hyundai's R-series of common-rail turbo diesels, the same engine family that appears as the larger 2.2-litre D4HB in bigger Hyundai and Kia models. It uses piezo injectors, which meter fuel more precisely than older solenoid types, and drives its camshafts by timing chain, so there is no belt-change interval sitting in the service schedule.

What made the R-series work so well in the ix35 is the shape of its torque delivery. Peak pulling force arrives low in the rev range and stays flat through the speeds you actually use, which is why a diesel ix35 feels unstressed with a loaded trailer where a petrol equivalent has to work harder for the same result.

The engine offered here is brand new, not reconditioned, and it is built to OEM fitment specification - every mount, sensor position and mating face sits where the factory put it, so it drops into the ix35 without modification. Internally, though, it is better than a straight copy. Where the original design loads its internals hardest, higher-grade components take their place: stronger connecting rods, an improved crankshaft and upgraded bearings among them. It fits like the factory engine and is built to outlast it.

After assembly, each engine goes through hot and cold testing. Cold testing turns the engine over without firing it to confirm mechanical integrity and oil circulation; hot testing then runs it under its own power to verify normal operating behaviour before it is cleared for sale. A heat tab is fitted before dispatch, which permanently records any future overheating event.

Where high-kilometre D4HAs show their age

Few of these engines fail without warning. By the time an ix35 has covered serious kilometres, the D4HA tends to wear the way most hard-worked common-rail diesels do, and recognising the patterns helps you choose between repair and replacement.

The bottom end is the big one. Bearings and connecting rods carry the highest loads in the engine, and once a bearing starts to go, a knock from the lower engine usually announces it. Bottom-end damage rarely stays contained - by the time it is diagnosed, the crankshaft is often marked as well, which is why partial repairs on a worn engine so often disappoint.

The fuel system ages alongside. Piezo injectors depend on clean fuel and fine tolerances, and worn injectors show up as harder starting, uneven idle, extra smoke and creeping fuel use. The DPF, particularly on an ix35 used mainly for short suburban trips, gradually loads with soot because its regeneration cycle needs sustained running to complete.

Add a turbocharger that wears its bearings and seals over time, and a cooling system that quietly degrades until a hot day and a loaded car find the weakness, and you have the usual suspects: knocking, blue or black smoke, oil consumption, power loss and overheating.

These patterns are exactly why the replacement engine's upgraded internals matter. The components most likely to have ended your original engine's life - rods, crank and bearings - are the very ones fitted in higher-grade form in the new unit.

Fitment, inclusions and how the swap runs

Fitment comes first. This listing covers the ix35 built from 2010 to 2015 with the D4HA, but production runs include quiet revisions to sensors, brackets and wiring, so we verify every order against the VIN before dispatch. Read the 17 characters from the windscreen base, build plate or rego papers and call 1300 200 320 - the check is free and usually done on the spot. If you drive another Hyundai or Kia with an R-series CRDi diesel, this listing is not matched to it; ask us and we will point you to the right one.

The engine is supplied as a long engine: the assembled block and cylinder head complete with crankshaft, pistons, connecting rods, camshafts and valvetrain. The turbocharger, injectors, manifolds, DPF and accessories are not included - they transfer from your old engine, and their condition deserves real attention. Ask your mechanic to check the turbo for shaft play and oil weep, have the injectors tested, and get the DPF inspected and cleaned before it goes back on. Bolting tired parts to a new engine is the fastest way to shorten its life.

Installation must be carried out by a qualified mechanic; it is a condition of the warranty as well as plain good sense on a common-rail diesel. The parts warranty runs for 12 months or 50,000 km, whichever comes first. Because a heat tab is fitted to every engine, overheating damage is identifiable and is not covered - so make sure the cooling system is flushed, pressure-tested and refilled properly at install time.

Freight is free Australia-wide, with the engine securely crated. From first phone call to a running vehicle, the steps are short: VIN check, payment, dispatch, installation.
