Was this a chemical flush? Did you put the "Subaru Conditioner" in?

It's probably just displacing air with coolant. Did you burp it?

Are the hoses original? I had one leak after I changed the fluid. Be sure an add the Subaru Conditioner regardless; it is cheap insurance.

You need to add the coolant conditioner every time you change the coolant with the earlier SOHC EJ25's. It's $1.50 a bottle at the dealer.

3 days will not make a difference, just leave 4 oz. of coolant out.

i think the stuff is made by ''holts'' so you might look for that.

great info from the outback forum, even if it isn't for your year, the basics apply.


Colin,
I am the tech manager at Prestone Antifreeze. Check out these service bulletins on your car regarding coolant loss

NUMBER: 08-52-08
DATE: 08/18/08
APPLICABILITY:
1999MY and later Impreza & Forester
2000MY and later Legacy & Outback
2006MY and later Tribeca
SUBJECT: Coolant Overflow
Introduction
If you encounter a vehicle which experiences coolant coming out of the coolant reservoir tank, it may be caused by the radiator cap pressure valve being stuck open by debris sucked up through the reservoir tank hose. As the cooling system cools down, it sucks coolant back into the radiator. If there is debris that settles to the bottom of the reservoir tank, the hose is low enough to also suck them back into radiator. This causes the radiator cap not to seal, allowing excessive amount of coolant to escape overflowing the reservoir tank. If this condition continues over time, there will not be enough coolant in the system to maintain proper engine temperature.
In order to correct the condition you need to clean (and test) or replace the radiator cap, clean out the reservoir tank, and shorten the hose slightly, following the repair procedure.
Production Line Change
http://www.alldatapr...17606/139876308
The shorter coolant reservoir tank hose was used in production as shown above.
Repair Procedure/Information
1.Radiator Cap Cleaning
Many caps can be successfully cleaned. The important part is the thorough cleaning of the negative pressure valve. If this is not done completely, remaining debris may result in a repeat issue. If there is an excessive amount of debris or the sealing rubber on the cap appears to be pitted or damaged, replace the cap.
Note: If replacing the cap, skip to Step 2.
http://www.alldatapr...17606/139876310
Using clean water and a brush, thoroughly clean the cap seal surface.
Note: A used toothbrush which has been cleaned works great.
http://www.alldatapr...17606/139876313
Manually open the negative pressure valve. Using clean water and a brush, thoroughly clean the valve (inner and outer surface) and the valve seal surface.
Check the radiator cap valve opening pressure using a radiator cap tester to insure the cap is within specification (refer to the applicable Subaru Service Manual).
Note: If the cap is out of specification replace it.
2.Coolant Reservoir Tank Cleaning
http://www.alldatapr...17606/139876561
Remove the reservoir tank (refer to the applicable Subaru Service Manual).
Using clean water, thoroughly clean the inside of the reservoir tank.
Reinstall reservoir tank. Fill with coolant to the Full mark.
Note: Be sure to use genuine Subaru Super Coolant or Subaru Long Life Coolant, depending upon what type of coolant is currently in the system.
3.Coolant Reservoir Tank Hose Modification
http://www.alldatapr...17606/139876563
Remove the hose from the reservoir tank. Cut 20 mm from the bottom of the hose at a 45°angle. Reinstall hose in reservoir tank.
Start engine and permit to fully warm up.
Turn off engine and allow to fully cool down.
Recheck coolant level in reservoir and add coolant if needed.
Note: Be sure to use genuine Subaru Super Coolant or Subaru Long Life Coolant, depending upon what type of coolant is currently in the system.

too long for one post, here's the rest of it.

NUMBER: 09-42-05
DATE: 04/15/05
APPLICABILITY:
All Models
SUBJECT:
Cautions Concerning Engine Coolant
INTRODUCTION
The purpose of this bulletin is to inform of cautions concerning engine coolant.
REPAIR PROCEDURES/INFORMATION
When adding, replacing or servicing the cooling system always use Genuine Subaru Long Life Coolant. Genuine Subaru Long Life Coolant is a phosphate (non-amine) type and is specially formated for all Subaru vehicles equipped with aluminum engines and radiators. Coolant of other types may not provide the proper protection to aid against corrosion of aluminum parts. If an equivalent must be used, make sure it is a phosphate (non-amine) type. As a reminder, use of Genuine Subaru Long Life Coolant is mandatory on all repairs paid for by Subaru of America, Inc, that require the replenishment of coolant. This holds true for any claim type.
Do not use flushing machines.

Posted Image

If a flushing machine has been used to service other brand vehicles with copper radiators, a chemical reaction between copper ions and Subaru coolant may occur. This could also cause clogging of the radiator.
If regular flushing is required, only use fresh tap water. Do not use hard water. Hard water will create calcium build-up which will clog the radiator.
Whenever the coolant is changed, you must add Genuine Subaru Cooling System Conditioner. Genuine Subaru Cooling System Conditioner has been tested and approved for aluminum engines and radiators.
Do not use after-market coolant reinforcement agents, sealers and/or flushing agents as those chemicals could corrode aluminum parts.

And last, the cylinder head issue-
NUMBER: WWP-99
DATE: 02/2004
APPLICABILITY:
2000-2002MY Subaru Legacy and Outback;
1999-2002MY Impreza; 1999-2002MY Forester
SUBJECT:
Engine Cooling System Conditioner
INTRODUCTION
Subaru of America, Inc. (SOA) has determined that over time, affected vehicles may develop small external coolant leaks at engine cylinder head gaskets. This is the result of normal expansion and contraction of engine components caused by the heating and cooling of these parts. To prevent cylinder head gasket leaks from developing or to correct existing leaks, a special Subaru Cooling System Conditioner should be added to affected vehicle cooling systems.
This Service Program will involve adding one bottle of Genuine Subaru Cooling System Conditioner to the engine cooling system.
AFFECTED VEHICLES
2000-2002 MY Subaru Legacy and Outback with 2.5L engine.
1999-2002 MY Impreza with 2.5L engine.
1999-2002 MY Forester with 2.5L engine.
Affected vehicles are identified in the VIN range chart below. Only vehicles with a 2.5L engine are affected.
NOTE :Prior to performing repairs, confirm coverage for potentially affected vehicles by using the Vehicle Coverage Inquiry in the Dealer Communication System (DCS).
http://www.alldatapr...69294/105869295
Vehicles identified in the preceding chart may include VINs that were not distributed in the U.S. market. Dealers will be provided a list of VINs that include the owner name and address. This information will enable dealers follow-up with owners of potentially affected vehicles. These listings contain owners names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is unlawful. Accordingly dealers are urged to limit the use of this listing only for the purpose of completion of this service program.
OWNER NOTIFICATION

A copy of the owner notification letter is included at the end of this bulletin.
OWNER REIMBURSEMENT FOR PREVIOUS REPAIRS
Owners are being advised in the owner notification letter, found at the end of this bulletin, that if they have previously paid an authorized Subaru dealer for repairs related to this Service Program, they may be entitled to reimbursement. The owners are further advised, to qualify for any reimbursement they must submit the original repair invoice to Subaru of America, Inc. Please review the owner notification letter, which explains this procedure so that you are familiar with it, and can assist owners with any questions.
FUTURE MAINTENANCE
In the future, it will be necessary to add Genuine Subaru Coding System Conditioner to the coding system of affected vehicles whenever the engine coolant is replaced.

CYLINDER HEAD GASKET WARRANTY EXTENSION
For owners of affected vehicles that have this Service Program performed promptly, SOA is extending coverage under the Subaru Limited Warranty for cylinder head gasket external coolant leaks to a period of 8 years or 100,000 miles, whichever occurs first Warranty coverage begins on the date the vehicle was delivered to the first retail purchaser. If the vehicle was used as a demonstrator or company vehicle before being sold at retail, warranty coverage begins on the date the vehicle was first placed in such service.
As a further condition for this extended warranty coverage to apply, the owner must properly maintain the vehicle's cooling system in accordance with the recommended maintenance schedule and Genuine Subaru Cooling System Conditioner must be added each time the engine coolant is replaced. Resulting damage caused by a lack of maintenance or low coolant level will not be covered. Replacement of the Cooling System Conditioner during inspection and maintenance services is not covered under warranty.
DEALER PROGRAM RESPONSIBILITY
Dealers are to promptly service vehicles subject to this Service Program at no charge to the vehicle owner regardless of mileage, age of the vehicle, or ownership.
For affected vehicles sold after the date on the dealer's computer list, dealers are to contact those owners and provide them with a copy of the owner notification letter. They should also arrange to make the required correction according to the instructions in the service procedure section of this bulletin.
http://www.alldatapr...69294/105869296
Vehicles in Dealer Inventory
Dealers are also to promptly perform the applicable service procedures defined in this bulletin to correct affected vehicles in their inventory (new, used, demo). Additionally, whenever a vehicle subject to this Service Program is taken into dealer new or used inventory, or is in the dealership for service, necessary steps should be taken to ensure the Service Program correction has been made before selling or releasing the vehicle.

http://www.alldatapr...69294/105869297
1.Install rags around the radiator filler neck to prevent coolant from contaminating the engine area.
http://www.alldatapr...69294/105869298
2.Take off the radiator cap and set aside.
http://www.alldatapr...69294/105869299
3.Extract 125ml (4.23 oz.) of coolant from the radiator using a suitable device such as a piston syringe, meat or poultry baster, antifreeze hydrometer, etc.
http://www.alldatapr...69294/105869300
4.Place the syringe into the overflow reservoir and push the coolant out of the syringe.
5.Shake the bottle of cooling system conditioner until all contents are thoroughly mixed.
6.Pour the entire bottle of cooling system conditioner into the radiator.
NOTE Posted Imageo NOT pour the cooling system conditioner into the overflow reservoir. The conditioner Will settle at the bottom of the reservoir and not mix in the cooling system.
7.Reinstall the original radiator cap.
8.Remove rags from around the radiator filler neck.
9.Start the vehicle and let it run until the engine is warm. This ensures the conditioner circulates and there are no air pockets in the cooling system.
Service Procedure on a HOT Engine
1.Turn the ignition key to the "ON" position (engine off).
2.Turn the air conditioning "ON" to cycle the cooling fans. Leave the air conditioning "ON" for approximately two (2) minutes. This will lower the pressure in the cooling system.

check for coolant on top of the block. There is a crossover pipe under the intake that has o-rings. maybe they could be leaking. just an idea of somewhere to look. I have only worked on a DOHC one time.

It's running down to the area you are seeing it from somewhere. You need a cooling system pressure tester and a UV leak detection dye.

started to leak between motor and tranny quarter size


which side of the engine?

are you sure it is antifreeze?

the only coolant that far back are the heater hoses or thew driver side head gasket, rear corner.

lots of things leak in the area of the rear of the engine, but not all are coolant.
