    I have a 2011 legacy with around 80k miles. It overheated due to rotted lower hose and bad radiator connection. Radiator and hoses were replaced by reputable shop( not so sure anymore) it started leaking again and coolant was blown around driver side on fans and top of battery more like sprayed all over than straight leak even into fins of radiator. Shop replaced rad again saying defective( no charge). same thing happened again looks more sprayed even into the fin area of the radiator. No more shop no I'm digging in. Pulled rad and checked all not leaking or overheating after 10 min run at 2k rpm top hose is hot but lower hose is still cool. Heater in car is working after warm up. Next step to pull thermostat and verify operation after that thinking maybe head gasket. Has anyone used the combustion leak detector? My coolant and oil have no indication of issues, oil color is fine and coolant nice green, no indication of head gasket leak( brown residue) on oil cap either and no blue or white cloud at exhaust. Engine also idles smoothly.

    I also did use the funnel system with car on ramps to burp air.
    I did notice that both rad hoses firm up after run ( pressure) and this should be relatively normal to a point. I didn't notice any bulge points on either hose after the 10 min run. Thinking if too much pressure could be leaking past lower rad clamp and spray around since that was the area that seemed to be the source.

    Any ideas on how to test water pump flow or any other ideas would be greatly appreciated.
