Do you have the text or the general idea of the TSB? Sorry for the off topic.
I replaced the thermostat once in my 88 Royale and could NEVER get decent heat from it unless I put cardboard over the radiator in the wintertime.
I recently changed the t-stat in MrsCrzydmnd'* to a 180 and she complains of not enough heat lately too, bad enough that she drives mine instead. I also used only one gasket. I have the Fel-Pro O ring new in the package in the shop, can post it tomorrow and maybe see if its different from yours?
