Lexus Timing Belt
Lexus Timing Belt
This belt is responsible for keeping the bottom end of the engine (the crank) in time with the upper end of the engine (cam or cams).
Typical Service Interval: 60k-90k
Timing belts may look brand new up until the day the break or cause problems. Mileage is the only real way to tell service interval.
Why do we replace/service:
A timing belt deteriorates over time – it stretches, can crack, and become brittle.
What happens if we don’t service:
If a timing belt breaks or the teeth wear off / strip off, on many modern engines, it means that the valves in the head interfere with the pistons in the block. If this happens while the engine is running, it typically means at minimum, the engine needs torn down, head removed and valves replaced. Some engines are not interference engines, but most are anymore.
General Recommendations:
Timing belts can be a somewhat expensive replacement, but timing belt maintenance is always much cheaper than the Lexus repairs that may be required should a belt break while the vehicle is being driven. On many vehicles, the water pump is behind the timing belt, or is driven by the timing belt. Many choose to replace the water pump when the timing belt is being replaced, as there is virtually no additional labor, and, should a water pump fail, the timing belt will have to be replaced, again.
