Having problems with your 1994 GMC Sierra ?

Just flushed cooling system. Now I have sloshing water sounds. 1994 GMC C1500 5.7L V. Is there a way to flush the air out of the system? It does not have the bleeder valve on the thermostat housing.

Hi this dan....temp is hovering around 220 on 97 gmc 5.7. Thermostat, water pump temp sensor, and flush has been done already. dont see any leaks anywhere. when first started the temp goes to 240 then back to a steady 210-220 and runs good. It still bothers me. why running so hot?? any suggestions. How do I find a blockage within the engin? Head gasket soes not appear to be leaking either.....thanks....
