coolant leak, 2k2 suburban
i have a 2002 suburban that keeps flashing me the low coolant light. i've checked the coolant lines, overflow tank, and radiator core repeatedly but there doesnt seem to be any leaking. i havent pressure tested the radiator/pressure cap yet but it sets off the light about once a week, would a hole that small show up?
anyway, today while i was adding coolant i heard some of it dripping onto the ground but i couldnt find where the leak was coming from for my life. what do you think is most likely:
1. a cracked overflow tank
2. cracked coolant line
3. hole in radiator
4. faulty pressure cap
5. i'm open to anything else you guys might think it is too
any help is appreciated, thanx in advance.

The factory 5.3 waterpumps are pretty bad about leaking & the gaskets too... GM has revised both with new #'s... Get a small extendable mirror & look under the center of the waterpump & see if it's leaking from the weep hole... Also check around & under the mounting gaskets.
