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

    Appears that the cap is faulty or the wrong one. The fluid level in my
    overflow goes up as engine heats and drops during engine off. Does the hose
    return to normal after sitting all night. You say you blew the hose out but,
    is there a clog in the fitting that connects the overflow bottle hose to the

  3. I would think it could only be the radiator cap bad or plugged
    recovery tank hose . When the coolant cools, it contracts and should
    draw coolant that expanded back into the tank. Unless the hose
    material has weakend. Perhaps a service station could pressure test
    the cap.

    It was the cap. Decided to toss $8 at a replacement cap and all is well
    now. Thanks for your comments.

    Yes, the cap is bad or your overflow tube is pinched. Instead of
    collapsing the radiator hose it should have sucked open the little valve
    on the cap and pulled liquid from the overflow reservoir. That should
    have required much less suction than collapsing the radiator hose.
