Fitting
- A tensioner is a belt job. Fit a new timing belt at the same time.
- Set the engine on its timing marks before the old belt comes off.
- Torque the pulley bolt to the factory figure and set the belt tension by the book.
- Turn the engine over twice by hand and check the marks again before it starts.
- Best fitted by a qualified mechanic.
