Coolant leak from the reservoir?
I’ve been having this coolant from the passenger side. The weird thing is that it drips from the wheel well/fender trims.
I put dye and no leaks were found under the hood not even any of the hoses. Could it be that my reservoirs got a crack in it?
How common do these things crack anyways?

Age, as well as hot / cold cycles eventually causes plastic to become brittle and crack. Rubber components (belts and hoses) also deteriorate for the same reasons. This is not unusual for a 20+ year old vehicle.

Common issue. Replace with a new reservoir and cap and consider it a good run for a 20+ year old piece of GM plastic.

When you are just starting out, there is no such thing as a stupid question. That is especially true working at a dealer, where you won't see too many old cars.
