Problems:
Oil sludge buildup
This engine model is known for oil sludge buildup, especially if oil changes are not done regularly. This can lead to poor engine performance and potential engine damage.
Timing belt failure
The 2UZ-FE engine uses a timing belt, which can wear out and break if not replaced at recommended intervals. A broken timing belt can cause significant engine damage.
Fuel injector issues
Fuel injectors can become clogged or fail, leading to poor fuel economy, rough idling, and reduced engine performance.
Ignition coil problems
Ignition coils may fail over time, causing misfires, poor acceleration, and reduced fuel efficiency.
Cooling system problems
The cooling system components, such as the radiator and water pump, can fail or leak, leading to engine overheating and potential damage.
Exhaust manifold cracks
The exhaust manifold on the 2UZ-FE engine can develop cracks over time, leading to exhaust leaks and increased engine noise.
Vacuum leaks
Vacuum hoses and connections can deteriorate, causing vacuum leaks that result in rough idling, stalling, and poor engine performance.
Sensor failures
Various sensors (such as oxygen sensors, mass airflow sensors) can fail, leading to check engine light illumination and potential drivability issues.
