Water boils at 100 deg and with the collant system under pressure, water will have a higher boiling point eg 110 deg.
I'm no expert but i'd say around the 98 mark should do it.

Does your old one close or is it always open?

it is a new one it closes 92deg

Iwent to ford people this morning .they said that ford dont make any other thermostats only 92deg well, back to the drawing board

Just because its new doesn't mean it works correctly. It took my mechanic 3 new genuine thermostats to get one that worked. He says it common. My temp guage sits just right now.
