I haven't changed the coolant in a 2004 Stratus before and am curious if there are any tricks I should know first.

    No Tricks!
    Position a clean collecting container under draincock location. Open radiator draincock located at the lower right side of radiator. Turn draincock counterclockwise until it stops. Remove coolant pressure cap and open cooling system bleed valve. Raise vehicle on hoist. 2.7L: Remove heater hose at heater tube located at the right front inner frame rail and direct coolant flow into container.
    FILLING - 2.7L
    Close radiator draincock by turning clockwise.
    NOTE: IT IS IMPERATIVE THAT THE COOLING SYSTEM AIR BLEED VALVE BE OPENED BEFORE ANY COOLANT IS ADDED TO THE COOLING SYSTEM. FAILURE TO OPEN THE BLEED VALVE FIRST WILL RESULT IN AN INCOMPLETE FILL OF THE SYSTEM.
    Open cooling system bleed valve . Attach a 1/4" inside diameter clear hose that (48 in.) long to the bleed valve. Route the hose away from accessory drive belts and radiator fan. Position the other end of hose into a collecting container. The hose will prevent coolant from contacting accessory drive belts and other components. Remove cooling system pressure cap. Attach a Funnel to coolant pressure container filler neck. Install a clip to pinch overflow hose that connects between the two chambers of the pressure container Slowly Pour coolant into Funnel allowing air to escape.
    Slowly continue filling until a steady stream of coolant flows from attached hose on bleed valve. Close bleed valve and continue filling system to top of DO NOT overtighten. TIghten to 12.4 N·m (110 lbs. in.). Remove clip from overflow hose. Allow coolant in Funnel to drain into overflow chamber of pressure container. Remove Funnel and install pressure cap on pressure container. Remove hose from bleed valve. Start engine and allow to run until thermostat opens and radiator fans cycle.
