Hello everyone. As some know I need to replace the the oil pump on my 07 escalade 6.2L I have gotten the oil pan removed. Now I'm looking to get the harmonic balancer removed and then take the Front engine cover off. My questions are is there anyone with knowledge on how to do the Harmonic balancer correctly, I heard I might need a flywheel lock tool, that is almost impossible to find in store, and if there's an alternative to that if I can't locate one. My second question minimum is needed to come off the front of the block (pulleys, belts, ect) to get the Front engine cover off.
