I am currently deployed and my wife wants to do a coolant flush on our suburban herself, I can talk her through everything except how to get to the petcock. I looked at it before I left and know that it won't be very easy but not sure exactly what will need done to access it. My question, is there an easy way to get to the petcock and if not what all needs to be done to access it?
