Remove the tool and tighten the retaining bolt removed previously to the specified torque in order to fit the tensioning tool.

It is good practice to check timing again by refitting the tools to the camshafts and adjusting the engine until cylinder no. 1 is set to TDC, measured using the dial gauge and probe.If the engine timing is not correctly adjusted or the timing belt is found to be faulty, the engine timing adjustment operation must be repeated.
