How to replace the camshaft timing chain, sprocket, and tensioner on 2008 Chevrolet Silverado 1500?

A person needs to remove the engine front cover as the first step to change the camshaft Timing Chain and sprocket along with the tensioner. Take out the Crankshaft position (CKP) sensor reluctor ring as a next step. When you install the ckp sensor reluctor ring correct its alignment to protect essential components and ensure optimal obd ii system performance. The device shaped like a dish which we call the reluctor ring needs to be oriented towards the engine front cover during installation. Push the ckp sensor reluctor ring onto the Crankshaft using the rear pinion bearing race installer (J 5590) but make sure the keyway on the reluctor ring and key on the Crankshaft match. Set this ring completely against the Crankshaft sprocket. Other steps in the installation process require replacing the engine front cover.
