10.4.14. You can drain 99% of the coolant by also unscrewing the knock
sensors out of both sides of the block. The rear bank is extremely tough to
access! The transaxle is in the way! I made a special tool out of a cheap
7/8 inch combination wrench,bent 90 degrees at the box end,With a map gas
torch. It’s a shame that GM used the block drain plug location to mount the
knock sensors!

Awesome video, so much detail then other videos out there, my only question
is what lower intake did you end purchasing since the doorman didn’t work?
Thanks

I can’t figure out why there is a coolant passage through the tensioner. Do
