Can a 5.3L Vortec leak hot coolant?
You may never see a small leak when the engine and coolant is hot because it evaporates immediately after it leaks. The 5.3L Vortec has a dry intake manifold therefore the leak cannot be there.

Can a low coolant reservoir cause a leak?
The only symptom most folks notice is a low coolant reservoir. This can be very misleading and simply adding coolant will only allow the condition to progress. A much worse practice is adding water to the system. Water dilutes the corrosion protection of the coolant. City water may also contain chlorine, fluorides and several minerals.
How can I tell if my radiator has an oil leak?
Coolant is forced past the piston rings and enters the oil crankcase. The coolant mixes with the oil into a brown or cream-colored frothy consistency. The radiator coolant level will drop perceptibly, while the oil level in the crankcase will rise. At this point, signs of exterior water leakage will show.
