My 2004 chevy trailblazer EXT LT with a v8 just started making a whirring sound when I accelerate and all of a sudden just started over heating I changed the thermostat it seems to overheat faster if I turn the heat on it gets hot fast and the check gauges sign comes on I hear bubbling and liquid leaking wan I turn the car off.

Have coolant system pressure checked for an internal leak like a head gasket. Also when hot turn off engine and check radiator for cold spots if you feel any rad is bad.

It sounds to me like you have a bad cooling fan. It screws in to the water pump shaft. It is a very, very common issue on these trucks and both of your symptoms are indicative of a fan issue.
