Engine Hyundai-Kia D4EA

The 2.0-liter diesel engine Hyundai D4EA or Santa Fe Classic 2.0 CRDi was produced from 2001 to 2012 and was installed on almost all mid-size models of the manufacturer of that time. This motor was developed by VM Motori and is known as the Z20S on GM Korea models.

In 2000, VM Motori introduced the RA 420 SOHC 2.0 liter common rail diesel engine, which was developed for the Hyundai Group and GM Korea and is also known as the D4EA and Z20DMH. Structurally, this is a typical unit for its time with a cast-iron block, a timing belt, an aluminum cylinder head with one camshaft for 16 valves and equipped with hydraulic compensators. To dampen excessive vibrations of the engine, a block of balancing shafts is provided in the pallet. The first generation of these engines existed in two different power modifications: with a conventional turbocharger MHI TD025M developing 112 hp and from 235 to 255 Nm of torque and D4EA-V with a variable geometry turbine Garrett GT1749V developing 125 hp and 285 Nm.

In 2005, the second generation of these diesel engines appeared, developing 140 – 150 hp and 305 Nm. They got a modern fuel system from Bosch with a pressure of 1600 instead of 1350 bar, as well as a slightly more powerful Garrett GTB1549V variable geometry turbocharger.

The D family also includes diesels: D3EA and D4EB.

The engine was installed on:

  • Hyundai Elantra 3 (XD) in 2001 – 2006;
  • Hyundai i30 1 (FD) in 2007 – 2010;
  • Hyundai Santa Fe 1 (SM) in 2001 – 2012;
  • Hyundai Sonata 5 (NF) in 2006 – 2010;
  • Hyundai Trajet 1 (FO) in 2001 – 2006;
  • Hyundai Tucson 1 (JM) in 2004 – 2010;
  • Kia Carens 2 (FJ) in 2002 – 2006; Carens 3 (UN) in 2006 – 2010;
  • Kia Ceed 1 (ED) in 2007 – 2010;
  • Kia Cerato 1 (LD) in 2003 – 2006;
  • Kia Magentis 2 (MG) in 2005 – 2010;
  • Kia Sportage 2 (KM) in 2004 – 2010.

Disadvantages of the Hyundai D4EA engine

  • This diesel engine is demanding on the maintenance schedule and the quality of the oil used, therefore, particularly economical owners often experience wear on the camshaft cams. Also, along with the camshaft, it is usually necessary to change the valve rockers.
  • According to the regulations, the timing belt changes every 90 thousand km, but often it breaks even earlier. Replacing it is difficult and expensive, so owners often drive to the last. It can also break as a result of the wedge of the water pump and the valves here usually bend.
  • This diesel engine is equipped with a completely reliable Common Rail Bosch CP1 fuel system, however, the nozzles quickly fail and begin to pour from low-quality diesel fuel. And even one faulty nozzle here can lead to serious engine damage.
  • Simple modifications to 112 hp do not have an oil separator and often consume lubricant, glow plugs last quite a bit, and the turbine usually runs less than 150,000 km. Also, the oil receiver mesh is often clogged and then simply lifts the crankshaft.
