TheGr8Doughboy Posted October 3, 2006 Share Posted October 3, 2006 Lurker on here... got some great help a while back with my 02 sensor not throwing a code. Car: 2000 Outback Lagacy with EJ25 Here's the trouble: I've got coolant dripping from the motor across the tierods and onto the exhaust manifold. I cannot see anything leaking from the top and I'm having trouble seeing where this is... or could be coming from. Driviablity has not changed. Only leaks when it's running... We just had a little trouble with the thermostat sticking so it's fresh coolant, t-stat and temp sender to the guage. Where do I look? Could this be HG?

ferret Posted October 3, 2006 Share Posted October 3, 2006 When you replaced the coolant, did you add the Subaru Coolant Additive? It's for the 1999-2003 SOHC engines to prevent and seal small external leaks. Usually from the lower rear of the head just about where you describe. Pretty cheap to try, just stop by a Subaru Parts counter and ask for it. They all know what it is. Quote Link to comment Share on other sites More sharing options...
TheGr8Doughboy Posted October 3, 2006 Author Share Posted October 3, 2006 I'll give that a try... however, it's leaking a lot. I drove about 1.5 hours round trip to school this morning and she sucked down the entire overflow resivior Quote Link to comment Share on other sites More sharing options...
TheGr8Doughboy Posted October 6, 2006 Author Share Posted October 6, 2006 Here's a picture of where it's leaking.... this is the firewall side of the motor between the head and the block on the EJ25... please help! Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 7, 2006 Share Posted October 7, 2006 Well that sounds and looks like the external HG leak issue; try a bottle of that Subaru stop leak, whoops I mean coolant additive. There's a TSB about it. You can get it at any dealer. It's a relatively small bottle, only maybe 4-6 oz i'd guess. I think I paid $3 for a bottle which is even a little steep. Guessing you burped all the air out of the system after changing the coolant. Quote Link to comment Share on other sites More sharing options...
the_bard Posted October 7, 2006 Share Posted October 7, 2006 How many miles are on it? Subaru extended the warranty on the '00 OBW external headgasket to 100,000 miles (or eight years). Simply put, if it's below 100,000 miles, a Subaru dealership should be able to dump the coolant additive, run it through for a bit (I think they said like 15-30 minutes), and see if it's still leaking at the deadline. If it is, they swap that headgasket. We ended up doing exactly that with my wife's 2000 OBW. Quote Link to comment Share on other sites More sharing options...
Suzam Posted October 7, 2006 Share Posted October 7, 2006 Hope you had the dealer put the additive in when the TSB was issued.:-\ If so, it's on record and you should have the dealer check it out. It does sound like the external leak symptoms. Quote Link to comment Share on other sites More sharing options...
