While poking around under the hood of my 2003 Forester X, I noticed that\nthe upper radiator hose was deformed, or crushed inwards. I released the\nradiator cap, there was a sucking sound as if under pressure and the hose\npopped back to normal. The fluid level was up to the bottom of the\ncap/filler neck in the radiator, and at the "full cold" mark in the\nreservoir. I cleaned the cap, and blew out the overflow tube to make sure\nit wasn't clogged. I ran the car for 25 minutes and noticed that the upper\nhose gets hot and hard, while the level in the reservoir doesn't move at\nall. After the engine cools for ~45 minutes the upper hose again deforms\nsome, while the level in the reservoir still doesn't move. The temperature\nguage moves to a smidge over the 1/3 mark and sticks there - it didn't move\nup or down at all. Is this normal? Cap faulty? Air in the cooling system?
