Took it back to the place I bought it (independent dealer who only sells Subarus), they saw no evidence of leakage, tightened all hose fittings, ran a pressure test (also fine), ran it up on the lift, and were unable to duplicate anything. They perform 30K service on all the cars they sell, and confirmed that the Coolant Conditioner was used.
Gave it back to me without the under cover, said to look for leakage. Didn't notice any at first, until I was filling up my tires today at the gas station, and could see a small drip coming from the driver's side onto the left exhaust pipe and then down to the ground. I can see coolant clinging to the bottom of the jacking point behind the oil pan, and around the driver's side steering rack boot.
1. Do external HG leaks in phase 2 EJ25's typically leak right after the car is started and running in the cold (I warmed it up for about 2 minutes and drove 1 mile to the gas station, it's about 14 degrees outside today)? Does the leak "go away" temporarily once it's heated up?
2. If by chance it's not the HG, what else could possibly leaking from that area?
I tried to crawl under and take some pictures if that helps at all. Not sure how to link them up but PM me and I can e-mail them to you.
I'm going to call the place first thing Monday and take it over to show them with me there what's going on, but wanted some thoughts from people who know a lot more than me!
