Should I Connect A Small Hose Connected To The Reservoir Tank Lid For Coolant In The Engine

Posted in Engine & DriveTrain | Asked on Sep 9, 2009

There are 2 hoses – one connects from the cap to the radiator and the other is about 3 inces coming out from the other side of the cap but just hangs there. I have a 2001 dodge stratus. I noticed it when I was adding antifreeze.

    It is for overflow, that is the way it should be.

    This is supposed to save the water so that it can be sucked back into radiator when it cools off, — water expands when it is hot and contracts when it is cold, — so when engine heats up some of water runs out through pressure cap (pressure blows it off off seat so water can flow out)-down the hose into the reserve tank, — when it cools –and sucks it back in the radiator is filled again this assures that it will always have enough water to cool poperlry, — (as long as water remains in reserve bottle)!….
    No hose connected, water shoots out on ground, — low water in radiator,– if any loss at all, the water keeps getting lower and lower,-till engine overheats, then a lot squirts out on ground, and car is ready for major repair, (of not stopped immeditartely)!
