im attempting to do a heater core flush on my 2004 and want to take the hoses off and on little as possible so was wondering if anyone could tell what size hoses in er diameter wise I'd need to get for a heater core flush for the inlet and outlet. The heat has been weak and when j floor it can hear a gurgling song be in the dash and heat will work for day or so then get weak again assuming core is pretty clogged. Coolant level is good and operating temp right 190. Plus one of the hoses is only lukewarm assuming it's the outlet hose. Thanks in advance and appreciate all the help
