O.K. the new temp control valve(126-830-07-84) was installed today and the washer fluid temp is now staying at 85 to 90 degrees. the other number (140-997-06-45) are for o-rings needed to install the new valve, not seals for where the heat exchanger penetrates the washer fluid reservoir lid, the number for the seals/grommets to do that job is 010-997-13-81.

Thanks again
Tim
