Drain and fill with 100% DI water. Run it for a day or two, drain and repeat one or two more times. Then you can be pretty sure that you won't be mixing enough coolant to possible cause issues, and running for a few days on 100% water won't hurt either. Besides, a gallon of pure H20 is a buck at the grocery store and you'll only need 6 or 8 to be sure you're flushed.

That might have been bad move. If its the one with stuff floating around in it then it seals all the leaks including ones you don't want it to seal like the radiator cap. It doesn't work with the headgasket leaks because the combustion gasses will reopen the hole once the goop gets in it.

The Subaru coolant conditioner has no solids like the Bars stuff. You are right that Subaru didn't make it themselves. It's Holts RadWeld See the similarities? lol

The bottles both having "Holt" on them and the same shape doesn't prove they're the same substances, but it's pretty strong circumstantial evidence.

I just had mine replaced at 105K, over the 8 year/100k warranty. Wrote to Subaru, they decided to split the cost.

I just returned from the dealer while having an unrelated recall rervice performed. They informed me that the head gaskets are leaking and should be replaced.

The oil looks fine, I don't add any coolant, and I don't see any obvious drips. Where or what else should I be looking for that would indicate the head gaskets are leaking?

Ask the dealer to show you what they found. Then you get the bonus of laughing in their faces if it's something stupid.

Yes, I should have asked dealer while I was there. I have looked fror signs of an external leak but haven't seen anything (unless I'm looking in the wrong place).

Any other suggestions on what I could check?

mine is not that bad of an external leak, when i had it on the lift you could see the oil leaking from the head gasket. easier to see with header off. i had to take my heat shields off the other day loud rattle, very annoying. thats when i got a good look. just keep an eye on your oil level and coolant. like every six months or so my coolant resivour will be about empty.

A bunch of us over at Subaruforester.org are exhibiting HG failures, leaks, or weeping. I, for one, am exhibiting HG weeping oil, coolant loss, bubbles in overflow after driving, high sodium content in uoa results. 05 ej253 with 65,996 miles. hg weep started about 3-4k miles ago, coolant conditioner always used with coolant changes at 30 and 60k maints. we are starting a group effort to write to soa ceo. come join us (problems and maintenance sub forum).

just back from the dealer here, 2003 Outback leaking oil and coolant. Quoted $2100 for head gaskets! 20 hrs. labor seems crazy to me...also contacted SOA to see if they'll step up and help, can't hurt to try.

I read they changed hg material for the 04 models, and if you go on edmunds it shows hg problems under the reliability section from 97-03, and then 04+ are good, but it could have just not shown up yet, but since others say its been fixed...

i thought that subaru blue bottle was a conditioner to prefent acidity or somthin and because somthin about the aluminium block, not a stop leak

but yeah stop leak can plug up stuff like your thermostat, heater core or at least the line too it ect

I forgot to update this thread since no one answered my question, many posts back, but about 4-5 months ago when putting on the uel headers, bam, drivers side head gasket leak, how do I know for sure, a suby shop mechanic on my local board helped me put the headers on and he pointed it out to me, the kicker, have about 27K on the car and not abused, well maintained, etc.

Just waiting for the weather to get nicer and will get it fixed under warranty as I still, now, at this point, have 6K left, but I am now worried about them placing the blame on the uel headers, which I know the leak was there at the time of install.

I guess I know why my car has stunk of anti-freeze for a very long time, why I fill the anti-freeze over flow tank on a regular basis, unless there is an additional problem as well? I am not sure to be honest what's leaking down there as I am not Mr. Head Gasket Expert, anti-freeze, oil or both?

My car also seems to like to drink oil, not crazy amount but def, at least 1 quart between oil changes.

Depending on the miles, you might be covered. My pop-in-law has a '03 Legacy w/66K miles and SOA owned up 100%.

They are changing his timing belt for free as well. He is as happy as a little girl. Thanks SOA.

Default 2.5 HG Leaks

Something I've been wondering about.

The 96-97-98 2.5s are prone to internal HG leaks. The 2000-01-02 2.5s are prone to external HG leaks.

So how about the 1999s . Do these have a mix or internal/external HG leaks ? This gets confusing.......since the 99s apparently could have either Phase I or Phase II blocks and either SOHC or DOHC heads.
( related question...the 1999 Legacys.......did these come from the factory with four different N/A engine configurations....ie.. the mix of Phase I/Phase II and SOHC/DOHC ? )

I just fixed an 05RS with 90k miles. Had external coolant leak on the bottom side of both heads and also an internal cylinder leak into the water jacket.

I have an external coolant leak on my 02 legacy. I had the HG replaced at 50,000 miles and it was under warranty. Now it is at 76,000 and it happened again. I called up SOA and they were good about helping me out. They told me to take it to the dealership for an inspection (~$50) and they would see if they could cover it. My Engine is not one of those effected by the warranty extension, but the guy at SOA said that since I have had it serviced and kept things up to date, that they wouLd "see what they can do." I take it in this afternoon.

my 07 impreza's head gaskets are in good shape with 85k on the odometer, however while changing my spark plug wires and plugs i came to find out my valve cover gaskets are shot. But those are 99% easier to fix!
