Coolant System Leak on my Subaru Forester

I have a 2009 forester non turbo. I haven’t been able to dive into it, but there is a coolant leak. It is coming from just under the front cover of the engine. I have checked the radiator cap, coolant tank for bubbles, oil for coolant in the oil, and the exhaust smells normal, not sweet smelling; all the normal signs for the usual head gasket issue these cars have. I was just curious what your thoughts were; because when I drive the car, it is a very slow drip, and same as the car is sitting and idling. Once I turn the car off, however, a bunch of coolant drips out for about 30 seconds. I do not let the car overheat, as I am always monitoring the fluid levels daily since I noticed the leak. Do you have any suggestions? It is a 2009 Subaru Forester X L.L. Bean edition

Perform a pressure test on the engine cooling system and find the leak. The vehicle is doing it for you when you see it leaking for 30 seconds when you turn it off. If you are unable to locate the leak in the 30 seconds you have I would hook up a pressure tester. This will allow you to apply pressure to the cooling system when the engine is cold and provide a longer amount of time to locate the leak. And if needed you can apply pressure over and over as it leaks down. Once you have located and repaired the leak it is a good idea to drain, flush and refill the coolant system.

COOLANT DRAIN, FLUSH & REFILL

1. Lift up vehicle.
2. Remove righthand undercover.
3. Remove drain plug to drain engine coolant into container.
4. Remove radiator cap so that engine coolant will drain faster.
5. Flush cooling system with clean, drinkable water.
6. Install drain plug.
7. Install righthand undercover.
8. Pour cooling system conditioner through filler neck.
9. Pour engine coolant into radiator up to filler neck position.
10. Fill engine coolant into reservoir tank up to “FULL” level.
11. Close radiator cap and start engine.
12. Race 5 to 6 times at 3,000 RPM or less, then stop engine. (Complete this operation within 40 seconds.)
13. Wait for one minute after engine stops, and open radiator cap. If engine coolant level drops, add engine coolant into radiator up to filler neck position.
14. Perform procedures 11 and 12 again.
15. Attach radiator cap and reservoir tank cap properly.
16. Start engine and operate heater at maximum hot position and blower speed setting to “LO”.
17. Run engine at 2,000 RPM or less until radiator fan starts and stops.
18. Stop engine and wait until engine coolant temperature lowers to 86°F or less.
19. Open radiator cap. If engine coolant level drops, add engine coolant into radiator up to filler neck position and reservoir tank to “FULL” level.
20. Attach radiator cap correctly.
21. Set heater setting to maximum hot position and blower speed setting to “LO” and start engine. Perform racing at 3,000 RPM or less. If flowing sound is heard from heater core at this time, perform procedures from 17 again.
