I put back the old thermostat it read 87C.Behr I think it's stil the original one I've owened the car for 12yrs. tempeture is back were it was running before just a bit past 80C mark it always stayed there from day one. I don't get this the new one read the same thing it ran 90C-95C what will run at in summer with a/c on 110C.
I forgot the user name here on this forum. He always writes (if it works don't replace it).
Thanks for all the replys
