Upper Radiator Hose Pressure??

Thanks for the input, I'll be picking up the pressure cap as well when in town on Saturday.

It's got the recovery tank setup on it. Overflow tank is what I call it though. Little Plastic Tank next to the Radiator with the hose from the Radiator to the plastic Tank. Tube is Clear but nothing is going into it when the fluid level does rise in the Radiator. Didn't have time to pull the plastic Tank before she left to go back to work. Will do that when she gets home tonight.

Thanks again for all the suggestions and help.

There's your answer right there;either the pressure is normal or the cap's relief valve is stuck, or the overflow hose is plugged.
