Cooling System - Chevrolet TrailBlazer 2003 Manual

Cooling System

When you decide it's safe to lift the hood, here's what
you'll see:
L6 Engine
5-30
V8 Engine
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down. The vehicle
should be parked on a level surface.
