recently i started to get a leaky radiator hose on the top of the radiator that feeds into the top of the block. it was leaking out of the hose connecting to the block. i replaced the hose thinking it had a crack or something. learking stopped but when i went to drive back up to my school i started to overheat. i couldn't figure it out. while i was driving i cranked up the heat on full blast and that brought my temp back down to midrange which is what it usually runs at. stopped into a little subaru garage and asked the mechanic. he said thermostat or headgasket. so i replaced the thermostat. no luck on the bringing the temp down and lost heat inside my car as well. then i read something about trapped air within the system and followed a procedure on how to remove the trapped air. no luck. i have a feeling that the antifreeze is not being circulated, which, i think means the waterpump is gone. the waterpump would take the hot water/antifreeze to the heating mechanism for hot air in the car as well as cool the engine. also, i have noticed that the top radiator hose gets so hot i can't even bare my hand on it. does anyone have any advice or gone through this situation with their subaru? i could really use some help on this one.
