There is no trick easy way.
I will warn you about a few things.
1. the idlers for belt fail and destroy the front timing cover. Replace them with belt. This includes the roller on tensioner arm.
2. the tensioner has a 19mm hex and is made of aluminum. The tensioner has a damper. You must apply force and wait for the damper to yield. Too much force and you break the hex off.
3. make a careful belt routing diagram. The belt will go on readily in a wrong routing and it slips when done the wrong way.
4. There is no hole for inserting a pin to lock tensioner in released position. There is a special tool that slides over spring and captures it. This means release, remove and fit belt, release tension again to finish install of belt.

This isn't the hardest belt I have ever installed but it is near the top of the list.

Once the tension is released, pull the belt off of the small smooth pulley that is towards the front of the vehicle( idler pulley/water pump). When installing slip the belt on the small smooth pulley as the last pulley to go around. Pulling the belt off and installing on the smooth pulley. Makes it easier to install the belt.

Does anybody know the torque specifications for the idler pulleys and the bolt on the tensioner? I've read to get the damper to yield I should not apply more than 177 lb/ft but just want to check for the other components. Thanks for any help!
