Legacygt97

okay. well looks like i got some work cut out for the next few days. thanks for the help.

now it is warmed up, and is slightly boiling out.

have been running car since last post with rad cap off. does not push seem to be getting too hot, does not push out water unless reved up slightly. ????

keltik: yes i do get boil over, and engine is VERY hot. nipper: radiator came from junkyard, did not do actual flow test, but when i too off hose for tstat with cap off water flowed freely. have not tried to see if it overeats with cap off. i will try it now.

engine was swapped because 2.5 blew cam seal twice, ran out of oil.... that was a very bad day.... i changed the radiator the other day, i had a spare kicking around, wanted to eliminate the bad radiator factor. Tstat was changed right bofore radiator. i know tstat is good, placed it in hot water(200 deg) and it opened fine. Yes i do have heat.....way too much. i had someone else suggest air in the system, but i bled it out. may not have done it correctly though?

oil looks good, it is at normal level and normal color. no moisture or smoke from exhaust. no signs of a leak.

230,000 miles, but about 70,000 on the engine. Engine was swapped around december. I believe the timing belt, waterpump, spark plugs, and a few other odds and ends, were replaced. The radiator should not be clogged, it has been changed anyways. but as edrach said , water spraying out of an open radiator cap would indicate a blown head gasket?

according to the manual, if it wera a waterpump failure it would be making a screetching sound, or would be leaking. it is doing neither. also i removed the radiator cap and turned it over, water SPRAYED out.

okay, heres what we got. a 1997 legacy 2.5 GT, with a 96 ej22 in it. Everything was perfect untill a few weeks ago, i was driving down the highway, at normal speeds, notbeating on it.. nothing. i got off the eamp and she overheated and stalled. i let it cool off, and then was able to make it back home , only having to stop to let it cool off twice, i had the heater on, it seemed to help. I asked a local subaru guru, and suggested the thermostat ( wich is what i suspected as well). So i changed the thermostat.. filled the coolant back up and let her idle for about 20 minutes......and AGAIN it overheated. i removed the thermostat and checked it by placing it in hot water.. it opened fine.. as did the old one. my father suspected the radiator... wich i happened to have a spare.. i changed that.. and still nothing. i resorted to the trouble codes.. as the check engine light was on.. this said that the knock sensor was bad.. i changed that as well... it was def bad because it was melted. the chk eng, light went out. but still it overheats. now the light is back on... but i do not want to spend another 75 bucks to get it checked again, and it flashes too fast for me to count the code. i suspected the temperature sensor.... changed it.. still nothing. AND the fans do not come on when it gets hot.. checked both fans.. both work. when i connect the connector to put in it diagnostic mode.. the fans turn on ... then off.. and keep switching on and off. i ooked up the fans to the battery, to force them to stay on... then started it. again it overheated.. what else could be wrong!?! PLEASE HELP!!!
