Step 2:

Step 3:
After the cam phasers and chains are installed. YOU MUST THEN ACTIVATE THE TENSIONERS by pressing on the chain above the tensioner pad allowing the tensioner plunger to fully compress and release. Make sure the tensioners properly activate and apply spring pressure to the chains. Once the tensioners are activated there is no way to deactivate them.
