Cooling System Bleeding
WARNING: This page is about a different car, the 2003 GMC Safari and 2003 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
DO NOT remove radiator cap when radiator is warm. Removing cap immediately lowers boiling point of coolant and could cause a violent overflow, resulting in large coolant loss and personal injury.
Place a large funnel in radiator filler neck. Pour one-half of cooling system capacity of DEX-COOL(R) coolant into radiator. Fill remaining capacity with clean, drinkable water to 0.5" (13 mm) below radiator filler neck. Start engine and let cooling system warm up. If coolant level drops when thermostat opens, add coolant as needed. Install radiator cap and top off reservoir. Check for leaks.
