Is the 203 Thermostat a Ford parts item I'd have to order, or is it usually in stock? Anybody have a part number? And what year 7.3 was it available for?

Thanks in advance.

It is not a factory item. Contact Dieselsite to purchase.
I run one of these in both of my trucks. They are great in the winter for high heater output.
