I've seen a few posts in the past on mystery leaks. I found mine. Just like the bulletin said.

Bulletin No.: 00-06-02-001

File In Section: 06 Engine/Propulsion System

Date: January, 2000

Subject:
Engine Running Hot, Overheating and/or Loss of Coolant (Polish Radiator Filler Neck and Replace Radiator Cap)

Models:
1999-2000 Passenger Cars and Trucks with Composite Radiator End Tank

Condition

Some customers may comment on one or more of the following conditions:

^ Engine running hot

^ Engine overheating, and/or

^ Loss of coolant/low coolant message


Cause

The radiator filler neck may have an imperfection in the sealing surface.

Correction

Important: DO NOT REPLACE THE RADIATOR.

Using a piece of 400 grit wet/dry sandpaper backed with a flat piece of wood, polish the filler neck sealing surface using a circular motion.

Replace the radiator pressure cap with a cap of the same part number as shown in the GM Service Parts Catalog.

:bash: GM quality control at it's finest.
