Isnt the top radiator hose the outlet from engine to radiator..filling that wouldnt matter, unless your waterpump or whatnot was going bad..
Mine the heater stops heating in winder at idle, but once I get the rpms up it works just fine

P.S. I dont have a shrowd either, and mine gets hot at idle in traffic...does the fan clutch also turn the waterpump?
