Engine Overview and Common Failures
The weight of the 2GR-FE engine according to the catalog is 163 kg. The engine number 2GR-FE is located at the junction of the block with the gearbox. Oil pipe rupture: Until 2010, the main oil supply line to the phase regulators had a rubber part that could burst, causing the unit to lose lubrication and even lead to bearing failure. Dealers only replaced the rubber hose, but it is better to buy the entire aluminum pipe. Cracking of the phase regulators: Owners often encounter cracking of the phase regulators when starting the car, but many continue to drive despite the broken coupling and unstable operation of the unit. A common problem with GR series engines is the cracking of the phase regulators when starting. For many, the only solution is to replace the sprockets, but often new couplings have to be purchased as well. In engines before 2011, the VVTi control valves were often replaced under warranty. Fluctuating idle RPM: In this engine, the throttle valve quickly becomes dirty, causing fluctuations in idle RPM, and until 2011, dealers even replaced the entire throttle assembly. Clogged injectors and fuel tank filter can also cause unstable operation. Other problems: Weak ignition coils, short-lived generator clutch, and water pump leakage before 50,000 km are also known weaknesses of this power unit. Engines manufactured before 2007 often had problems with leaks at the cylinder head gasket joints.
