Hello I will help you with your question,
When you say you want to set the timing belt or ignition timing?
The belt timing marks
The ignition timing is set by the PCM and is not adjustable
Let me know what you need and I will help you
OK now I understand you question better
This is the odd bank
IMPORTANT: Due to the loss of the reference timing, you will have to rotate this camshaft sprocket until the timing mark on the camshaft sprocket "springs" into the 120 'clock position. This may require up to 9 revolutions. If the camshaft does not spring to the 12 0 'clock position, camshaft timing will be incorrect.
This is the even bank
Time the camshafts on the even numbered bank cylinders (driver side), using the two step process.
NOTE: Install the timing belt following the procedures outlined in following steps. Make sure that timing marks are not disturbed during this operation. After installing the timing belt, make sure that all the timing marks are in their proper position. It is very easy to mis-install the belt and be off a tooth, which could cause driveability problems.
With the timing marks in their proper position, position the timing belt with marks, noting the direction of rotation
