Hi! There

The dash is removed to be able to remove the hvac box. The hvac box must be removed to replace the heater core. This is about an 8 hour job. To do the job see below. If you have any other questions on this just ask.

Hi Lee,


Thanks for responding so quickly. Do you have removal & installation instructions (including pictures) from a GM service manual?. Our mechanic already has All Data

info but it is very vague. He has gone home for the day, will be in at 7 a.m.


Thank you.

Sorry! I don't have the chevy manual instructions. I will opt-out of this question and see if another expert has the GM manual instructions.
