Engine Toyota 2AD-FHV

The 2.2-liter diesel engine Toyota 2AD-FHV or 2.2 D-CAT was assembled from 2005 to 2015 and was installed on European versions of such well-known models of the company as Avensis, Auris, RAV4. The unit was distinguished by the presence of a sophisticated exhaust cleaning system Diesel Clean Advanced Technology.

Along with the 2AD-FTV diesel engine, a more powerful version made its debut in 2005. Unlike the conventional modification, this power unit was immediately equipped with piezo injectors, and also had a more efficient VGT liquid-cooled IHI turbocharger. And in all other respects it was the same diesel engine with an aluminum block and cast-iron liners, a 16-valve aluminum block head with hydraulic lifters and a timing chain drive. Denso’s common rail fuel system with HP3 injection pump generated pressures of up to 2,000 bar. The designers did not do without a block of balancing shafts characteristic of such motors.

A feature of the unit was the Diesel Clean Advanced Technology exhaust cleaning system, which neutralized not only carbon monoxide and soot particles, but also nitrogen oxides.

The AD family includes diesel engines: 1AD‑FTV, 2AD‑FTV, 2AD‑FHV.

The engine was installed on:

  • Toyota Avensis 2 (T250) in 2005 – 2009; Avensis 3 (T270) in 2009 – 2015;
  • Toyota Auris 1 (E150) in 2006 – 2012;
  • Toyota RAV4 3 (XA30) in 2008 – 2012; RAV4 4 (XA40) in 2012 – 2015;
  • Lexus IS XE20 in 2005 – 2010.

Disadvantages of the 2AD-FHV engine

  • First of all, engines from this line are known for regular breakdown of the cylinder head gasket and frequent erosion of the mating surface of the aluminum cylinder block with a head.
  • In second place there is a high consumption of lubricant, and from the first kilometers of run. The manufacturer at first even changed the pistons under warranty, but this did not help at all.
  • Servicemen recommend changing the washers under the nozzles approximately every 60,000 km or they will burn out. After that, it becomes difficult to dismantle the nozzles without damaging them.
  • All these problems are typical for a modern diesel engine: rapid contamination of the EGR valve, jamming of the turbine geometry due to soot, low resource of the piezo injectors and the SCV valve, regular failures in the regeneration of the particulate filter, as well as failure of its nozzle.
