radiator leak?

[mmartins44]

I've got a 2002 SR5 with 163,000 miles.
I have an issue that not sure what it could be. I'm leaking about 1/4 of a gallon of coolant a day. The radiator was replaced about 4 months ago, it cant be that. Could it be my water pump seal is cracked? I replaced one back at 80,000 and by the math, I might be up for a new one. Is there something I can do to reduce the leaking?
Another question, I plan on having this car for only another 6 months. does it make sense for me to replace the timing belt if the water pump needs replacement?

Any other expensive items I need to be aware of soon?

Can you actually see the coolant leaking from somewhere? If so you must clean the area and watch it carefully to find out exactly where it is originating from. If your level is dropping but you don't see any visible leaks, you may be losing coolant some other way. (bad head-gasket, etc)
