Toyota 1AD-FTV, 2AD-FTV engines
Content
The Toyota automobile company has AD series diesel engines in its product line. These engines are mainly produced for the European market with a volume of 2.0 liters: 1AD-FTV and 2.2 2AD-FTV.
These units were developed by Toyota specifically for their small and medium-sized cars, as well as SUVs. The engine was first installed in second-generation Avensis cars after restyled models (since 2006) and on the third-generation RAV-4.

The engine number of these models is stamped on the side of the exhaust manifold on the engine block, namely: on the protruding part at the place where the engine is docked with the gearbox.
Motor reliability
An aluminum block and cast iron liners were used to create this engine. Earlier generations used Denso common rail fuel injectors and a catalytic converter. Then they began to use non-repairable piezoelectric injectors and particulate filters. These engines have been modified 2AD-FHV. A turbine is installed on all modifications.
In the early years of operation of these engines, serious problems arose, such as oxidation of the cylinder block and soot ingress into the engine intake system, which led to a large number of recalled cars under warranty. In engines manufactured after 2009, these shortcomings were corrected. But still, it is customary to consider these engines unreliable. These engines were installed on cars mainly with a manual transmission, only a six-speed automatic was installed on the 150-horsepower version. The timing chain changes at the interval of 200 -000 km. The resource of these models was laid by the manufacturer up to 250 km, in fact it turned out to be much less.
Maintainability
Despite the fact that the engine is sleeved, it is not repairable. Due to the use of an aluminum block and an open jacket of the cooling system. The dual-mass flywheel does not withstand the load and often needs to be replaced. As mentioned above, until 2009, there was a “disease” in the form of cylinder block oxide on a run from 150 to 000 km. This problem was “treated” by grinding the block and replacing the head gasket. This procedure could be done only once, then - the replacement of the entire block or engine.
Also on the first modifications were Denso fuel injectors with a resource of 250 km and maintainability. A mechanical emergency pressure relief valve is installed on the fuel rail of the FTV modification engines, which, in the event of a breakdown, is replaced as an assembly with the fuel rail. Antifreeze is drained through the water pump of the cooling system.
One of the major “sores” of these engines is soot formation in the USR system, in the intake tract and on the piston group - this all happens due to the increased “oil burner” and leads to burnout of the pistons and gaskets between the block and the head.
This problem is considered by Toyota under warranty and damaged parts can be replaced under warranty. Even if your engine does not consume oil, it is better to carry out soot cleaning procedures every 20 - 000 km. Among owners of diesel engines, error 30 often occurs during their operation, but it occurs only on 000AD-FHV engines and means that there is some kind of problem with the differential pressure sensor.
Tips for choosing oil
1AD and 2AD differ from each other in the following: in the volume and in the engine of the 2AD-FTV model, a system of balancers is used. The drive of the gas distribution mechanism is chain. Oil in 1AD models is best filled with diesel approval for diesel engines according to the API - CF system according to ACEA -B3 / B4. For the 2AD model - with approval for diesel engines with a particulate filter C3 / C4 according to the ACEA system, according to API - CH / CI / CJ. The use of engine oil with particulate filter additives will extend the life of this part.

Reviews of motorists
Reviews of the owners of these motors characterize them as very fastidious and capricious engines that must be very carefully monitored and looked after. Otherwise, all the money saved on fuel will be spent on the repair of these units.
Knowing all the problems of the internal combustion engine, Toyota, subject to the timely completion of routine maintenance for Europeans, extended the engine warranty from 5 years to 7 years and from 150 km to 000 km, depending on which event comes sooner.
