Answer 1

These thermostats are located under the housing where the lower radiator hose attaches to engine.Do not skimp here get thermostat from Subaru dealer this will avoid throttling of the thermostat which often happens with some aftermarket thermostats.---i.e. engine going up in temp then cool down every 2 minutes while cool out This cases excessive wear of the head gaskets among other things.Be sure that the spring end is towards engine.Also be sure one of the little cutouts in the O ring for gasket is lined up with the checkball weight in thermostat.Remove the plastic screw in top of radiator,this will aid in bleeding when refilling radiator.Fill radiator slowly be patient coolant has to flow around the checkball in thermostat.rapid filling will cause ball to shut.After topped start engine and run for 10 seconds,turn off,refill again.Bring recovery tank to full mark.Reinstall plastic screw in radiator,radiator cap.Start engine bring to normal temp upper radiator hose will be hot when this temp is achieved.Stop engine allow to cool top radiator once more
