I am the owner of a volvo 740 gl 1990 . the upper hose in my radiator is becoming compress after running for about two days and I think that do not allow the water to run fluidly .I open the resevoir tap and the hose return to normal shape.I changed the hose ,the thermostat but that did not fix the problem. The car is running fine but I know that this is not normal.

Sounds like your radiator cap is not allowing air to draw into the overflow tank when the engine cools down. Change your radiator cap.
