For me that is quite typical. In-fact no dealership I have ever dealt with has ever sold the tools. Parts yes, tools no. This includes GM and Ford. You probably were looking at tool number J-45695 no? Most tools are given a Kent-Moore number. All of Nissan's specialty tools can be bought from them via their Nissan/Infiniti outfit via http://www.nissantechmate.com
When it comes time and what I typically do is use a Prestone "kit" they have out there that hooks into your radiator hose and allows you to attach a garden hose for an extended flush time. There are also radiator flush solutions that you would drain your system, add this in, top off with water, bring to operating temp, then flush the system several times with fresh water, then add your correct coolant mix back into the system. I will probably also give a go at doing something with compressed air and try to "blow" the block out to get as much of the pockets of coolant from in there also.
I'll be sticking with Nissan brand coolant though in hopes that it is chemically engineered to work better with our engines metallurgy. Pricing difference is negligible to me.
