Toyota Repair: Timing Belt Checks, crank pulley, auto repair books

Question
Hi Ted,

I have a 1995 Camry 4 cyl AC with 156K miles. The Toyota garage put on a new belt in 2000 when the car had 63K miles. Because of your ability to empower me to accurately fix other things on my Camry, I plan to tackle changing the timing belt. After reading over the directions in two auto repair books, I have some questions that I would like to ask you.

Once the bolt is out of the crankshaft, will the crankshaft pulley come off easily by hand or is a puller required?

If the timing notch on the crank pulley moves clockwise a little bit when retorqueing the 19 mm bolt, is it OK to turn the crank counterclockwise to set it to 0 again?

When the timing belt is installed on all the pulleys and the crank pulley is on but not tightened, should I rotate the engine by hand two times to make sure the crank pulley mark lines up with 0 and the camshaft timing mark lines up with the bearing cap at the same time before tightening the crank pulley bolt?

If I keep the crank pulley set to 0 and the hole in the camshaft pulley lined up with the timing mark on the bearing cup, will the car need timed with a timing light when it is all put back together?

How do I know if the tensioner spring needs replaced?

Many Thanks Ted for your help!

Sincerely,

Mike

Answer
In most cases the pulley can be puuled off by hand,if not a couple of prybars will do the job,in extreme cases a puller may be needed.
Yes you can move the pulley back to zero.
Yes, rotate the engine and recheck the timing marks.
If the timing belt is installed correctly a timing light is not needed.
Tensioner springs never wear out.
