replace radiator cap it acts a 2 way valve to let in or expel coolant from and into the recovery tank as it heats up and cools down.

Welcome to Fixya

You need to add few ounces of coolant to the reservoir. The reservoir is located under the hood. It is a white plastic that has liquid in it. Please see picture below of the coolant reservoir.

Thank you for using Fixya!

This indicates a low level of coolant in the coolant bottle/resevoir..... this symbol represents the radiator or coolant system liquid level.

Warning comes on to warn of coolant level too low.

When the engine is cold...remove the cap and check level. Add 50/50 antifreeze/water to level indicated on the side of the coolant bottle or tank.

Reservoir Bottles/tanks are usually transparent and you can see the coolant level through the plastic.

When coolant topped off to correct level, lamp will go out automaticly...no need for scanner or shop to turn it off. It will come on as a 'self check' when you turn on the ignition and if level is okay will go out when engine starts.

Yes you can do it yourself

Degas Bottle Removal

1. Drain radiator (8005) until engine coolant is out of degas bottle. Disconnect radiator overflow hose (8075) and engine coolant vent hose at degas bottle.
   

1. Remove power steering oil reservoir retaining screws and position power steering oil reservoir (3A697) out of the way.
   

1. Remove degas bottle return hose and clamp. Remove degas bottle retainers and remove degas bottle.
   

Installation

1. Position degas bottle in vehicle and install retaining screw and nut. Tighten retaining bolt and nut to 9-12 Nm (80-106 lb-in).
   

1. Connect degas bottle hose and clamp to degas bottle.
   

1. Position power steering oil reservoir onto degas bottle and install retaining screws securely.
   

1. Connect radiator overflow hose and engine coolant vent hose to degas bottle.
   

1. Fill and bleed engine cooling system as described. Check for coolant leaks and proper engine coolant level after engine reaches normal operating temperature.

I would add coolant to the overflow reservoir. There is not radiator cap on the radiator itself.

Check to see if the fan on the radiator is working at idle.

Here's information on how to change the fan if needed:

Engine Cooling Fan Removal & Installation 2.4L Engine To Remove:

1. Remove the coolant bottle and set aside.
2. Remove the power steering reservoir and set aside.
3. Disconnect the cooling fan connector.
4. Remove the cooling fan mounting screws and the cooling fan.

To Install:

1. Install the cooling fan and the mounting screws. Tighten to 50 in-lb (5.5 Nm).
2. Connect the cooling fan connector.
3. Install the power steering reservoir.
4. Install the coolant bottle.

3.7L Engine To Remove:
NOTE: If the fan blade is bent, warped, cracked or damaged in any way, it must be replaced ONLY with a replacement fan blade. DO NOT attempt to repair a damaged fan blade.
NOTE: For 3.7L Heavy Duty/Max Cool/Trailer Tow cooling package, the viscous fan cannot be removed separate from the shroud. Both fan and shroud must be removed together.

1. Disconnect battery negative cable.
2. Using special tool #6958 spanner wrench and #8346 adapters, remove the viscous fan from the water pump.
3. Gently lay fan into shroud.
4. Disconnect the electrical connector for the electric fan, then disconnect connector from shroud.
5. Remove the two fan shroud mounting bolts connecting the fan shroud to the radiator.
6. Remove the shroud and fan from the vehicle.

To Install:

1. Install fan shroud assembly into the vehicle. Tighten fan shroud to radiator bolts to 50 in-lb (5.5 Nm).
2. Install shroud mounting bolts tighten bolts to 89 in-lb (10 Nm).
3. Connect fan motor wire connector to harness connector, and attach connector to shroud.
4. Connect negative battery cable.
5. Start engine and check fan operation.

Add coolant 50 / 50 mixture water to coolant in the overflow resovoir...

you drain it from the radiator petcock on the bottom and you fill it from the overflow tank however I seem to remember those cars as having a radiator cap if i'm not mistaken it is on the passenger side if not in is the overflow tank
