The thermostat is a non servicable item. It is a common part that can be found in any autoparts store and is fairy inexpensive (I don't remember the part number for it). Since you need to order other stuff for your D from one of the Vendors, I would (assuming that you need a new one) order it through them...you'll be sure to get the right one.
