Radiator Hose Pressure
I noticed my radiator hoses has quite a bit of pressure after about an hour of driving when adding power steering fluid. How much is it supposed to pressurize, I could hardly squeeze the hose. I know the system is supposed to pressurize but not sure if its supposed to be like that. After about 2hours of cooling there is still pressure in the hoses but still cannot pinch the upper hose completely.
Radiator cap was replaced a couple months ago I bought off pelican. Waterpump/timing belt and radiator were replace a year ago.

I hope you used Dexron ATF not PS fluid. My car seems to be the same way as yours in terms of the pressure and I did notice it but I didn't think anything of it.

I'd guess somewhere in the 11-12 PSI range - maybe as high as 15PSI. I have a pressure bleeder that I use and never go more than around 11PSI to test for leaks and bleed based on what I have read on forums in the past.

Try bleeding your cooling system; do it every week if you have to. If you get air every time, your head gasket is leaking and you're pressurizing your cooling system via the leak.
The good news is that your car can actually go on like this for months, even years (ask me how I know...) before you decided enough is enough and replace the HG.
