overheating!!!! HELP!!!!

[130fe]

Like the others have said, it sounds like an air pocket. Are your fans coming on at the programmed temperature? Do they run all of the time or when they are "supposed" to come on. I never had any luck using the bleeder screws so I just removed them totally. The best way I have found to avoid air pockets in my LT1 is to fill the engine block (with coolant) through the upper hose (the one right below the throttle body on top of the water pump). Just disconnect it from the upper radiator hose barb and then reconnect it to the radiator when the block is full. I fill it through the radiator hose and take my time allowing all of the air to "burp" out as I fill it and then fill the radiator to the top. See if that works for you and post up your results.
