My 07 2.5L 4cyl Auto Subaru Outback with 220000 kms (136000 Miles) needs attention. I’m in Australia if that’s useful.
It already leaks oil, and the mechanic says it’s a faulty head gasket; he suggests I monitor the oil level every 2000 km. It’s a minor leak, and the repair cost isn’t worth it.
Here is my issue: today I parked my car and when I returned 2 hours later, I saw a puddle. I thought it was strange as I, up until then, only knew of a minor oil leak. I put a tissue in the puddle; it’s green. Great.
I drove home to inspect the engine. Coolant is below the low level, and there is a greenish residue on the right side of the engine covering the radiator, battery and all areas in between. I couldn’t find where the source was. Radiator has coolant on the surface, as seen in the picture.
I haven’t noticed any overheating or white smoke from the exhaust pipe.
I appreciate any thoughts on what it may be. I love this car. Thank you in advance.
