Toyota 2ZR-FE/FAE/FXE 1.8L Engine Specs, Problems & Reliability

Toyota 2ZR-FE/FAE/FXE 1.8L Engine Specs, Problems & Reliability. The 2ZR-FE engine took a middle location in the power series of the ZR family, in between the 1ZR and 3ZR engines. This 1.8-liter four-cylinder gasoline engine was presented in 2007 and quickly became an alternative for the 1ZZ-FE power unit. Toyota produces some different variations of the 2ZR depending on vehicle models (for example, routine Toyota Corolla or hybrid Toyota Prius) and markets (Europe, Japan, The United States and Canada and etc).

Toyota 2ZR FE FAE FXE 1.8L Engine Specs

The base 2ZR-FE has an aluminum cylinder block with spiny-type cast iron liners, steel connecting rods and light-weight pistons with resin-coated skirts. Pistons are cooled by engine oil sprayed on the bottom of pistons by oil jets mounted inside the engine block. An aluminum 16-valve cylinder head is mounted on top of the block with a triple-layer metal type cylinder head gasket in-between. The engine is geared up with a timing chain and two overhead camshafts. Valves are activated by roller rocker arms. The valvetrain consists of hydraulic lash adjusters for a consistent zero valve clearance. Consumption valve size is 31.9 mm; exhaust valve size is 27.4 mm. The 2ZR engine has variable consumption and exhaust timing – Double VVT-I system. Camshaft specs (intake/exhaust): duration is 246/234 degrees; valve lift is 9.9/ 9.7 mm.

The engine got a plastic consumption manifold, digitally managed throttle body, and Toyota’s ETCS-I (Electronic Throttle Control System – intelligent). The 2ZR-FE engine has a sequential fuel injection system, which equipped with 12-hole injectors. Likewise, this engine received a contemporary electronic ignition (DIS) with coil-on-plugs. Spark plugs are iridium-tipped thin-electrode type. The exhaust manifold is made from stainless steel.

The 2ZR-FAE version (2009 – present) changed the 1ZZ-FED totally and likewise the base 2ZR-FE engine in some lorries. The 2zr-fae functions the Valvematic system and increased compression ratio. The Valvematic system continuously adjusts an intake valve lift and improves fuel effectiveness. With Dual VVT-I and Valvamatic system, this 2ZR version takes in 5-10% less fuel than the 2ZR-FE and produce slightly more power.

The 2ZR-FXE (2010 – present) is another adjustment of the 2ZR-FE engine, utilized primarily in Toyota’s hybrid models such as Toyota Prius, C-HR hybrid, Lexus CT200h. This engine features Atkinson cycle operation, VVT-i for the intake camshaft only, 13.0:1 compression ratio, and cooled exhaust gas recirculation (EGR) system. The 2ZR-FXE changed the 1.5-liter 1NZ-FXE engine, formerly used in the Toyota XW30 Prius.

2ZR-FE/FAE/FXE Engine Problems and Reliability

2ZR engine problems are the same when it comes to the 3ZR engine series. Among them are progressive oil usage, unreliable cooling pump, Valvematic concerns, and noisy operation.

The ZR engine family united the most sophisticated innovations for the naturally aspirated engines that Toyota established. All this impacted adversely on reliability. The engine has a great deal of small problems that ruin the overall impression of it.

Frequently, owners report high oil consumption. Progressive oil consumption is common for engines of the very first years of production. Oil leakages are not unusual, generally from an oil filter or from under the timing chain cover. Also, the water pump has brief durability (40,000 miles). Before its death, the pump generally begins to leakage or produce sound. On the whole, the engine is loud. Increased noise can be related to the timing chain or chain tensioner. The timing chain becomes extended after a 100,000 miles mileage.

The consumption manifold rapidly covers with dirt, which results in floating rpm. If you bought an automobile with high mileage, it is meaningful to clean inside the consumption manifold and throttle body (valve). Regardless of its undoubted contribution to sustain economy and effectiveness, Toyota’s Valvematic system in 3ZR-FAE engines is another nuisance. Any issue with it causes a complete replacement of a pretty expensive Valvematic unit.

These problems are typical for the 3ZR as well. The typical engine life for 2ZR-FE/FAE is about 150,000 miles (250,000 km).
