Is it normal? It has been like this for 5 years and 80,000 km. Heats inside. Co2 test than does not show.

Privet, radek

Are these the heater hoses or the radiator hoses ?

Radiator hoses

Based on what I've seen on my '97 855, using OEM Volvo hoses, I would say it's not normal for good radiator hoses to be hard. New OEM hoses are definitely soft and pliable. With age, the hoses sometimes become harder. Sometimes the hoses have a date code stamped or printed on them. You could check to see if your hoses have a code on them. If they are really old, that could explain why they are hard.

They are hard after heating. Nothing else happens. The fluid does not disappear. Does not throw through the cap. Maybe the cap does not release excess pressure?

Once the car is hot they will be hard from pressure , that is normal!

Yes but V70 II B5244T3 has softer hoses. I can clamp the hose halfway. In my engine, just push a little.

With a normal functioning rad cap, those hoses will be under 21psi of pressure. 2/3 the pressure that your tires have. I'd be more looking into the other car on why it's not building pressure in the cooling system.
