Toyota’s AR engine series began its history relatively recently – the first units appeared in 2008. At the moment, these are popular engines that are respected by drivers of Japanese cars to a greater extent in the United States and Canada. Although, some members of the family are spreading all over the world.
The 2AR-FE/FSE/FXE engines received a number of significant differences from the 2AZ series, which they replaced. Among them are lightweight pistons and pins, a cylinder block made of aluminum with thin cast iron liners. In addition, the gas distribution mechanism is Dual-VVTi and the volume increased to 2.5 liters.

A fairly good family of motors – both in terms of design and operational parameters. The units are quite durable and practically do not show any problems. The exceptions are the characteristic knocks from the VVTi clutch in a cold state, the pump leaks, which are solved by replacing these components.
In addition, it should be borne in mind that the cylinder block is disposable and cannot be repaired and, in the event of a skew, requires a complete replacement – that is, reinstallation of the motor. In general, the Toyota 2AR engine is reliable and durable and can go more than 300 thousand km without problems. Naturally, in order to extend the resource, it is necessary to comply with the manufacturer’s requirements – regularly carry out maintenance, pour only high-quality oil and gasoline.
