As long as the timing belt has not been removed yet and the tensioner pulley is still tight, you can rotate the crank pulley to wherever you need it to be.
You can use the bolt, or you can turn it with the big hex, or grab it with your hands if you have enough strength.

Dumb question, but clockwise?

On a 7th gen 1.7L D17 type engine you should always rotate the crank CCW due to the floating tensioner.
On other engines I have no issue with rotating the crank either direction as long as the tensioner is not loose

wytas is an unknown quantity at this point

Re: DIY: Timing belt 96-00

alright i am at step 15, i put the sensor, lower cover and pulley on. When i set the crankshaft to TDC on the lower cover the camshaft is at TDC, but when i rotate the crankshaft one revolution (back to TDC) the camshaft is not at TDC, the “UP” is at 6 oclock, so every other revolution on the crankshaft to TDC sets the camshaft to TDC, hope this makes sense, is this correct?

My two cents worth...
consider the diameter of the camshaft pulley versus the diameter of the crankshaft pulley.

No, it says to rotate the crank 5-6 times to check if its all good, but what im saying is, are they suppose to spin at the same rate, 1 full crank rev to 1 full cam rev? or is it 1 full crank rev to 1/2 cam rev? because they aren’t the same diameter as mentioned in the post above, it would make sense they don’t spin at the same rate

The cam gear is twice the size of the crank gear. They cannot spin at the same rate.

Crank-cam ratio is always 2:1
