The 2UZ engine was intended for heavy, off-road cars, pickups, and with this there are some changes and improvements that distinguish this engine from the 1UZ-FE. First of all, the engine has increased in volume due to the increase in the cylinder bore and piston stroke. Peak torque occurs at medium revs.The cylinder block is made of cast iron, not aluminum. The Compression ratio has been reduced to 9.6 units.
O
therwise, the engine has the same cylinder head design. The timing drive remained belt-driven, the intake camshafts rotate, and the outlet camshafts rotate through the gear. The engine was produced until 2010 and then it was replaced by 1UR-FE.

Frequent problems
The Toyota 2UZ engine is one of the representatives of a fairly well-designed family of internal combustion engines, and so much so that there is simply no need to talk about shortcomings and operational problems among caring owners.
The motor simply does not have technological errors and quickly failing elements. When filling with high-quality oil and using clean gasoline of the appropriate brand, as well as regular maintenance, the engine resource often exceeds half a million kilometers. This despite the fact that not only about any accidents and overhauls, but also minor shortcomings are out of the question.
