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![Icon Confused](https://ls1tech.com/forums/images/smilies2/icon_confused.gif)
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.
