Quote: All you posted sounds pretty good. What about the cap, was it new w the rad?. Tho spitting after only 10 minutes seems not right (to me) & it might have just been an air pocket letting a hot spot develop causing steam making the big jump in psi. Stay in touch
The radiator cap is the original cap that I re-used on the new radiator. I will drive it again in the morning and see what I find. The car show is only 2 miles away and then it will be sitting all day as I roll through the swap meet aisles!!!!
