Car was at the dealer last on 12/2019 for a new water pump (coolant leaking) and oil cooler O-ring (it was leaking). The dealer changed the oil and the coolant and everything was working fine.

11 months later, I do my own oil change. I drain all of the old oil and then slowly remove the filter, I put the drain plug back with a new crush washer and install a new filter and make sure it's tight. I notice some green fluid (very tiny amount). I also notice a small amount of engine oil. I check the drain plug, it's dry. I tighten the oil filter a bit more and let the car sit overnight. Today in the morning, there was a drop or 2 of oil on the floor.

I took the car for a drive to run my errands and noticed the car is really struggling to make power. It revs fine. Coolant temp seem to be normal.

I got home and noticed some steam out of the front of the engine. I checked the coolant reservoir, it's completely empty. I am suspecting the radiator is leaking or on its way out.

I am thinking of using my Toyota Camry and going to pick up some coolant from the Subaru Dealer and check the radiator when the car is cold tomorrow morning. At least I may be able to drive it to the dealer that way.

Any other suggestions, please let me know what you think.

Common for the end tanks on either side of the radiator to split open. I had to replace the radiator on mine. It's a slow leak. Obvious because of white crust on edges.

Oil drip on floor - That will take some cleaning and careful monitoring to find.

The oil dripping may be due to some of the stuff that came out and landed on the plastic cover.

I took some of the new oil out and inspected it, I don't see any coolant.

I just bought 2 gallons of coolant (Damn, this stuff is EXPENSIVE) so I can refill the system and drive to the dealership on Wednesday.

Refilled the coolant today and drove 28 miles to the dealership I trust.

As suspected, they discovered the lower radiator hose is leaking, the radiator itself is leaking and the cap isn't venting correctly...(not sure how that works)

They will be replacing all 4 radiator hoses, the radiator and the cap.
