Find the leak, if external? Radiator--hoses--heater hoses--gasket, somewhere--water pump. You can check the coolant for oil or coolant in the oil. The coolant leak could almost anywhere.
I did see a service bulletin for your vehicle. The fan shroud may rub a hole in radiator? If so, the radiator would have to be replaced. At the bottom of fan shroud you would use cushion tape in a couple of places. Use a small spacer washer at the top bolts. I can give you more info, if you think the fan shroud is the problem?

You must replace it with a new one along with the timing belt. Here are some guides and diagrams (Below) of how the job is done on your car. The guide is a general one but still give you an idea on what to do.

Here are the parts on Amazon water pump and timing belt with tensioner for $107.00 and its AC Delco which is the best brand.

Book gives it 2.7 hours but it might take a little longer. Set some time aside and have fun.

Please let us know what happens and upload pictures of the problem.
