Quick Disconnects
 

Quick question in regard to quick disconnects. I have 1994 GM Z-71, 5.7/350 and am getting ready to chqange all of the hoses, to include the heater hoses. Does the quick disconnect end, at the intake manifold, of the heater hose require any special tools to disconnect or do you simply squeeze the plastic ears together and pull it loose form the manifold connector. Also, does the new hose come set up with all of the new parts to re-attach it to the manifold or do I need any special parts/tools to re-attach.
