Toyota 3ZR-FE/FAE 2.0L Engine Specs, Problems, Reliability

Toyota 3ZR-FE/FAE 2.0L Engine Specs, Problems, Reliability. In 2007, Toyota introduced a 2.0-liter four-cylinder gasoline engine, which came out of the ZR series. The 3ZR variation ended up being successor for the 1AZ engines. The 3ZR-FE engine is used mostly in front-wheel drive vehicles such as Toyota Corolla, Avensis, and 2WD RAV4. The 3ZR-FAE is offered as a power unit for both FWD and AWD/4WD models (Toyota C-HR or RAV4).

Like the 1.8 L 2ZR-FE engine, the 2.0-liter variation has a die-cast aluminum cylinder block with spiny-type cast iron liners. The distance between its cylinder tires is just 7 mm. The engine block is really light and compact. Enlarged displacement was attained by installing a new crankshaft with increased stroke by 9.3 mm. Likewise, the crankshaft is positioned inside with 8 mm balanced out to the consumption side of the bore centers.

The cylinder bore size was unchanged. The engine got steel connecting rods and aluminum pistons with complete floating-type piston pins, resin-coated piston skirts, and low stress piston rings. The 3ZR engine block is equipped with piston oil jets also.

The 3ZR engine has an aluminum 16-valve cylinder head with chain-driven dual overhead camshafts. Valvetrain includes 2 intake valves and 2 exhaust valves per each cylinder, hydraulic lash adjusters, and low-friction roller rocker arms. The engine uses a roller chain with an 8 mm pitch. The 3ZR-FE engine has a dual VVT-i (Variable Valve Timing – intelligent). The 3ZR-FAE engine has a dual VVT-I and Valvematic variable lift system for the intake valves. The Valvematic system uses constant adjustment to intake valve lift and timing.

3ZR-FE/FAE engines have a sequential fuel injection system with 12-hole injectors and the latest Toyota’s ignition system DIS with Electronic Spark Advance (ESA). Each cylinder was geared up with thin-electrode type iridium-tipped spark plug and private ignition coil. The intake manifold made from plastic for weight reduction. It is fitted with a linkless-type throttle body and Toyota’s Electronic Throttle Control System – smart (ETCS-i). Two three-way catalytic converters are integrated into a stainless steel exhaust manifold.

Toyota 3ZR-FE/FAE 2.0L Engine Problems and Reliability

The ZR engine family united the most innovative technologies for the naturally aspirated engines that Toyota developed. All this affected negatively on reliability. The engine has a lot of little problems that spoil the total impression of it.

Most often, owners report high oil intake. Progressive oil usage is typical for engines of the first years of production. Oil leakages are not uncommon, generally from an oil filter or from under the timing chain cover. Also, the water pump has brief longevity (40,000 miles). Before its death, the pump normally begins to leak or produce noise. On the whole, the engine is noisy. Increased sound can be related to the timing chain or chain tensioner. The timing chain becomes stretched out after a 100,000 miles mileage.

The intake manifold quickly covers with dirt, which leads to floating rpm. It is significant to tidy inside the intake manifold and throttle body (valve) if you purchased a vehicle with high mileage. In spite of its undoubted contribution to sustain economy and efficiency, Toyota’s Valvematic system in 3ZR-FAE engines is another nuisance. Any issue with it leads to a total replacement of a quite costly Valvematic system.

These problems are normal for the 2ZR also. The typical engine life for 3ZR-FE/FAE has to do with 150,000 miles (250,000 km).
