bluerunner Posted June 3, 2010 Share Posted June 3, 2010 Bought this car, 97 legacy outback 2.5, a few weeks ago and had it overheat on the way home because the radiator cap was loose. A few days later I was driving and i noticed that my car was overheating so I went the mile home, got there to find the reservoir full. Let it cool down and the radiator resucked all of the fluid out of the radiator. I stopped today for maybe fifteen minutes, got back in and started driving, not even five minutes later I noticed my temp guage showed me over heating. Pulled into a gas station popped my hood and there was antifreeze coming out of the reservoir all over the ground. Fueled up, after my tank was full the radiator had sucked all of the fluid back into the radiator and filled it back up. Added somemore coolant to the reservoir and turn my car on to find the temp was fine. Drove around making several stops all afternoon. After I got to my final stop started my car and started driving and noticed I was starting to overheat. I let it get to 90% on the guage before I turned on the heater which was pumping HOT air and regulated out the temp guage. After I turnned off the hot air my temp was fine and stayed fine for the fourty minute drive home. I did notice there is some sludge in the reservoir and the guys records show he replaced the radiator three months ago. Any ideas? Besides replace the headgasket. Anything I can test to see if it's the thermostat? Thanks, Willy Link to comment Share on other sites More sharing options...

98LGTLover Posted June 3, 2010 Share Posted June 3, 2010 Yeah.. If you have oil in your coolant then you probably have the headgaskets going out on you.. Link to comment Share on other sites More sharing options...

bluerunner Posted June 4, 2010 Author Share Posted June 4, 2010 To replace the headgaskets, how hard is it and do you really have to pull the engine? Link to comment Share on other sites More sharing options...
subikid90 Posted June 4, 2010 Share Posted June 4, 2010 If you are mechanically inclined it is a 1 day project. I pulled the motor to do mine because it was easier. Many people have done them without pulling the motor. -Subikid90 1997 Legacy GT 5spd & EJ251 w/EJ25D heads ~10.5CR 1998 Legacy GT Limited waiting for EJ22T hybrid swap Link to comment Share on other sites More sharing options...
something different Posted June 4, 2010 Share Posted June 4, 2010 classic description of head gaskets leaking combustion into water. if you can, pull the motor. lots easier. foreign car mechanic, first time for ej25, pulled engine, total time for job 6 hrs. tom Link to comment Share on other sites More sharing options...
timbaru Posted June 5, 2010 Share Posted June 5, 2010 this was happening to my 96 and i replaced the water pump, removed thermostat (i live in hawaii) and bypassed my heater core and it fixed the problem. Link to comment Share on other sites More sharing options...
something different Posted June 6, 2010 Share Posted June 6, 2010 no matter where you live removing the thermostat is not a good idea. it may result in increased coolant flow (not good) and engine may never reach operating temp (poor fuel economy. you may have had a bad water pump, but also may have head gaskets just starting to fail. overheating in the beginning can be very intermitant. tom Link to comment Share on other sites More sharing options...
