I have a gurgle in my engine and suspect there are air bubbles after my thermostat and coolant tank replace. I'm a noob with car repairs but I have a lot of repair bills so I'd rather do it myself. Are Cobalts fairly easy to burp or should I recruit a more auto-minded assistant?

Easy to do. Fill the expansion tank to cold mark. Put heater in max heat. Idle the engine at 2000-2500 rpm for 3 minutes. Let engine idle for 30 seconds. Turn off engine and let cool. Squeeze the top radiator hose to expel any air and check coolant level.
