Here is one good video on changing the timing belt of Honda Pilot.

Here are some note I write on this:

In order to complete the timing belt job, we need to keep track of the following major checkpoints, a.k.a. critical points:

1. Loosen the crankshaft bolt -- deal or no deal situation
2. Timing marks and manually crank the shaft -- extremely critical
3. Pulley tensioner -- when to pull the hydraulic pin 

To facilitate the job, there are steps (some are not shown) to keep in mind

1. Drain the coolant from the radiator -- don't want to make a mess
2. Drain the power steering fluid and then remove the power steering pump -- reverse these later 

Additionally

1. We earnestly need that power tool to loosen the bolts
2. We need a 3/8 or 1/4 torque wrench for water pump -- to ensure all the gasket is properly sealed but not too tight
