yes, as far as I have heard, the "kit" is something that Courtesy put together themselves. first off, if you are going to order it, they forgot to add a gasket for the thermostat, I got one from Advance Auto for a buck. Secondly use the search feature, there is lots of good info on doing it, as well as a pix that shows a small hose that would be a good idea to change while your in there doing the rest. I second the notion about them maybe giving you a hard time about using your own parts, and might end up charging you at least three hours labor if not more.

I wasnt sure if I was up to the task of doing it myself either, but a friend of mine talked me into it, said it would be fun, so we did it, put about six hours into it, wasnt that bad to do, just take your time and notes, or pix as you go for future reference. I dont know what year/model you have, mine is the SC version, so a few extra bolts to turn than the non SC, but I still didnt think it was that bad to do.
