i got a new one from Napa for $140. Advance was the next lowest in Central AR.

 

Looks like it was the radiator cap. I removed the old one to find the seals cracked and the spring to be perminatly compressed. So i replaced it an just went on a 700mile trip with some good uphill driving and i never went over 210.

thanks for the help

 

that is a good deal.
