Disadvantages of the 2AR-FSE engine
- This motor is considered one of the most reliable in its class;
- When starting the engine, a characteristic crackle from the VVT-i can be heard;
- The water pump sometimes gives up on a run of 50 – 80 thousand kilometers;
- After 200 thousand km, there is a high risk of stretching a single-row timing chain.
