Ok, this engine has a timing belt and the recommendation is replace the timing belt and timing belt tensioner every 120,000 miles for normal service. Severe service which is defined as either mostly mountainous roads, gravel or dirt roads and climate of 0 degrees or 110 degrees, recommendation is every 105,000 miles
This a reliable engine with few issues, the main ones being failures of the crank sensor, vvt actuator solenoid, and coils, but their failures are no worse or more often than other vehicles
