Heating/Cooling System Problems Brewing? 120-130

posted by  someone claiming to be Volvolious-J on  Mon Nov 19 16:34 CST 2007 [RELATED]



OK Guys,

It seems hard to believe that all of these problems could be related to simple leaks and subsequent air into the system. Would that halt the flow such that fluid is not circulating into the heater core? Why would the hoses to the core be hot to the touch after a run?

Also.... why would I need a new radiator cap...? I though the thermostat unit was located inside that cast metal unit that flows into the top hose going to the radiator. Isn't that thermostat rather important to the whole operation of things?

Also... how could I diagnose if my water-pump/impeller is failing? I'm also hearing a disturbing clunking noise sometimes, which I've never heard before, and does NOT sound healthy...
