See if the local auto parts near you rents a pressure tester. Fill the coolant system up then pressurize it to see if you can detect where the leak is.

You know I replied to this yesterday or day before and asked for VIN number whether it was 1 or K because it's a different procedure and never received a reply.

Okay, it is a VIN number K. See picture for instructions. What is not said is power steering pulley may need to be moved out of way and harmonic balancer and engine mount may have to be removed as well to get all the bolts out. System may need bleeding after install.
